Why has the plasticote paint on my bike come off when I applied clear car laquer?
Answers:
because it did not have the plastic primer applyed first
laquer has solvents that remove acrillic latex paint, you need to
use latex paint on the plastic after priming the surface
The paint comes off because you applied clear lacquer. Lacquer thinner acts as a for most other paints. because lacquer is thinned with lacquer thinner, it follows that it will also remove most other types of paint.
I think I understand why you wanted to use lacquer to make your bike look better.
If you have to spray a gloss coat to your bike, make sure that it is of the Polyurethane variety, It will look just like lacquer, but it won't peel your paint.
