I thought I would share somthing I did the a couple weeks ago -that failed.
I wanted to paint the plastic on my dirt bike--- So while at the paint store they had a gallon of duplicolor "especially for plastic" laquer thinned primer.
I put on two coats--over 220 scratches --let it dry in the sun a few days--
then used some PPG DBC (using laquer thinner instead of the correct reducer) and cleared it with some Upol clear.
All of the plastic looks great except the tank--which pealed off---right at the gasoline level--after about 3 days. The top plastic that has not touched fuel was fine.
--Most of you probably knew that would happen----haha---at least I only wasted a couple of hours and some scraps.
I am interested in opinions---can a plastic gas tank be painted if I had used 2k primer--or maybe had hardened base??
Or is all paint over plastic going to fail--when there is gasoline on the other side?/
All the other plastic still looks great --even after some off road crashes-
