Painting gas tank exterior
« on: July 08, 2020, 20:32:10 »
When my car was restored, the restorer painted the bottom of the tank battleship grey.  Two years later the grey paint is coming off in sheets, revealing matt black paint underneath.  How were tanks coated originally and what type of paint should I use to repaint the exterior?

The tank was black, use RAL 9005 2K. If you do it yourself, this is also available in spray can.

Hans,

You really have to use 2k (2 component paint).
1k paint cannot withstand petrol so well.

Proper prep is everything.
