Hubcap painting

[BaronYoungman]

In order to ensure a good job/ and save some money, I am going to tape off the hubcaps(1971) myself.  Is the best bet to use the 1/4" blue plastic tape sold at the body shop supply stores...or to use masking tape and then razor blade out the areas.  The thin blue tape seems to work, But I don't know what kind of finish to expect. and it isn't the most exacting where as the tape seems to be very exacting but I don't know how the edge will look.  Advice?

Thank you,

I used a bit of a hybrid approach. I used the small blue tape to mask the ridge between the star and the first ring and to get the contour on the outer curve. I masked the star and cut it with a razor knife. We are waiting on the fifth hubcap to come back from the plater before we put the paint to the metal as it were. I will be curious to hear other reports.

Mine are at the painters as we speak. I got the impression they were up to the challenge of masking it off -- although the second person I spoke to started hemming and hawing about the quoted price -- stating how much labor was involved. My fingers are crossed...

Ahhh John, I can only hope mine turn out so nice. Did you use an exacto to get the final edges?

Also, I am guessing these are from the 190? what is that small rectangular piece?

John,

Yes, great pics (seen them before) and love the finish but some explanatory words would paint a thousand hubcaps!

I am in the same boat.

I'd like to help, but I didn't paint them.  They were done by the shop.  I assume they used various widths of masking tape, obviously the thinner tapes can be contoured much more precisely.  I suspect on the outer rim, they used thin tape for the inner cut line and then piled on the wider stuff to cover.  I'm sure a sharp trimming knife fits into the picture, but some of these tapes are 1/8" thick.  You would need to visit a professional paint supplier, preferably with a hub cap in tow to get advice.

The rectangular piece is the radio delete plate without the logo.

I use a metal stencil with a handle on it. It works great, just set it on the hubcap and paint. I don,t know if you can get them anymore. You still need to mask the outer circle but that is easy.

I have no experience with it, but heard it can leave jagged edges.  I'd defer to your experience.  The rubber version is worthless.

I'm in the same situation needing to repaint the hub caps, I was going to go the route of masking tape, if a stencil is still available I might want to give it a try assuming they are still available. Does anyone know where they might be found?

Mark,

I have the silicon rubber stencil that worked great for me.

If you would like I'd loan it to you.

let me know

fwiw,
I know 2 professional restorer's for the MB's( business's of restoring W113's, 300 SE 6.3's, Gullwings, 190SL's, 300SL's, etc,) mask them off with the tape themselves, then give them to the painter.  It IS time consuming. Patience required.

I've asked them if there were a stencil, and if so why not use them... they both said it's not precise enough.  Of course, these guys are selling their perfection in restorations to those who want to afford to pay for it so there's some latitude for the rest of us.  

I don't know if they ever use an exacto knife to trim though... I rather doubt it, but will ask next time I see one of them.  I would think there's always the good possibility of scratching the chrome layer though when using the knife to trim.

You really don't want to use:
ordinary masking tape for the painted egde
a sharp knife that will scratch the chrome
one of the silicone rubber stencils

The plastic tape won't let paint bleed in and make a fuzzy line
sharp knife should be obvious
The silicone rubber do-dad is worse than ordinary masking tape. Makes a mess and is basically useless.

Think of it this way. You want your hub caps to look nice and stand out, right? Take the time and mask them yourself or have a pro do it for you......

I'm going to be starting this project in the next couple of weeks.  I have a question abou the paint.  What paint did you use?  Do you use the dual stage (basecoat & clearcoat) or just single stage. Where did you get it? I have been to the paintscratch.com website and they sell the paint there but is there a better place?

How many coats of paint and or clearcoat do you put on?

Any recommendations would be helpful.

I'd like to know where to get the paint as well, I've taped my wheelcovers but have not tried to paint yet as the weather has been too cold but it is starting to warm and I'd like to do it soon.

Another question and I think it's important...and that is at what point do you carefully pull off/remove the tape after painting? Immediately after all paint is applied when still wet or do you wait a few minutes/hours ? or do you wait till it is totally dry?  I'm guessing before it is dry but any tips would be very helpful.

I just had mine done by a professional auto paint shop. Two times before, I went the route of stripping, taping, and painting them myself with the closest thing I could get to dark blue paint. Problem was all I know how to use is Krylon. So a lot of prep for a so-so look.

This time, I just let the shop do the whole shabang. 30 dollars a wheel which struck me as reasonable. They masked with tape -- just not sure exactly how they did it. Then they used a basecoat and clearcoat finish. I am very happy with the results. I would not grade it A+ but a solid A-. Of course, my rims are the originals so the chrome is not perfect either. Wheels are a big part of the 230SL look.

As for color -- I took the Glasurit code (332) to the local paint place. In a matter of seconds he converted it to the formula for the paint they sell. Matched my hard-top exactly.

I just finished painting five hubcaps. I used an old cap as a trial, and that was well worth the time for me. I used tape (the blue 3M tape for the inside ring was just right). I painted them with several very light coats of new metal primer and let that set for about an hour. Then I went with two very light coats of the finished color, came back in an hour, did two more light coats. Then I let them set for an hour or so and then, very carefully peeled off the tape. The critical item was making sure you completely pulled the tape and were very careful about not letting it touch the finished surface, since it was still a bit tacky. The results were great.
The blue, flexible 3M tape works very neatly. It is very important to use the flexible tape as it does not give any ridges, or spaces where the paint could seep onto the chrome (that you want as a clear and sharp line).

It is also important to make sure you can cover/protect the paint just after you spray them to ensure that there is minimal to no particulates falling to rest on the shiny finish.

Actually the $30 sounds pretty reasonable. It took me about 20 minutes per cap just to do the taping.

o.k. jonny B, I'm game to ask.... what are you using to apply the paint to the nicely masked off hub-caps?  Seem's like a lot of overkill to use a professional spray gun for the small amount of paint used on 4 masked off hubcaps.... so is there some other cheaper (DIY type) simple spray gun that will give even spray pattern? or am I stuck going to the pro's at auto-body paint shops?

I purchased the orginal hubcap painting mask kit for the small and full hub caps. I haven't had a chance to use  it but comes summer I will be doing some testing. I understand a good hint is you place magnets under the hubcap to keep the branding tool in place a large cover is used to fill in the slotted holes and prevent paint from getting on the chrome.
I also am new to a small HVLP gravity fed paint gun. Low pressure high volumn. I have some test hub caps I purchased long ago , my first victims!!!
The  orginal hubs-caps 040 black I had painted are ok from 10 feet away but  if you look at the detail the tap lines are poor quality. I should as a detailer for 38 years be able to do better even with my eyes closed.

I ordered my hubcap paint from a online company last week.  It comes in a spray can.  I'll post my results when finished.

I've never tried one of these disposable type sprayers and I own  HVLP equipment so I should use that on mine when the weather gets good enough to paint outside but I've heard people say if you are careful you can get good results with them on very small jobs like hubcap painting.  see link below...

I must sheepishly admit I used a rattle can for the painting, and the color match for the car we are doing is so close that it is dang near impossible to tell. This just so happened to work for the car we are working on, (and we did test it first). Sort of like using the almond rustoleum for the interior of the bumpers.

I used a rattle can also. My car is 040 black, so easy match. I clear coated it after several very very light coats. It has held up perfectly. I have the metal stencil and it did a very good job. I wax the hubcaps and clean them regularly, even with Westleys bleche white and the paint has held up.

[RBYCC]

I'm going to try something different.

I'll prepare the hubcaps for painting by sanding.
I intend to use a 2mil spray mask typically used to protect metal parts in shipment.

I'll spray the whole cap area, then use an Xacto knife to cut the outline of the painted area, then peel off the mask.

Prime with a metal etching primer then top coat and clear.

Result will be in peeling the mask off and see if there was any bleeding.

Painted the first hubcap today after several hours of taping with 3M green.

Used self-etching primer and spraycan enamel. Color came out pretty good but the surface has the typical spray paint matte finish.

If I want to get some luster and shine like the finish on the car, do I spray the hubcap with Clearcoat?

If yes, then I'll leave the tape on for a week or so until the clearcoat arrives. Hope I can remove the green tape after a week with no ill-effects.

Clearcoat: yes or no?
