Sinking paint

[Paint munky]

Ive painted a plastic bike panel where ive used filler (UPOL) on various parts of it, then primer and wet flatted which looked perfect at this point then i put the base coat on and in the areas where ive used filler the paint has sunk, what have i done wrong?

If its celly paint thats about par for the course.Theres so much thinner in the paint it softens the previous applications which causes the shrinkage.Time is a factor,the longer the filler is left the harder it gets.2k primer doesnt soften the filler and is ok even with celly top coats.

Right so its the celly paint thats doing it then, how long roughly should i be leaving the filler to dry? can i speed up the process at all?

could try better prep on the filler , light coat of primer and flat , repeat and so on until its nice

its the primer that needs longer to dry if anything , filler is gone off within 30 mins

Cheap filler I'm afraid, it's known for sinking and pinholing, it's ok for bogging up old transits but if you want a decent job to be proud of you need to use Upol Fantastic, a few quid extra but does what it says on the tin !!!

That'll be the problem then.

Anyone want a whacking great tin of filler

Could buy an old Transit

Must agree about the Upol Fantastic.Its brilliant stuff!Not hard work sanding either like some other expensive fillers.
