Painting plastic

[j.o.y.ride]

My first thing to paint will be plastic bits, headlight bezels, something in the grille (maybe the bezel, maybe the grille itself). Which primer is recommended for plastic, and is it advised to sand first?

And while at it... clear coat suggestions welcome.

Sand, then clean with alcohol. No primer necessary with Krylon. Begin with light layers - better to do 10 light layers of paint rather than 3 heavy ones. Clear coat afterward.

There are rattle cans of etching primer that are specifically for plastics. You can sand but just to etch or slightly dull the surface. A scotch bright pad is adequate.

Are you colour matching? If not then use PDip. No sanding needed and if you don't like it, peel it off.
It's the Franks Red Hot of 'painting'. "I put the $#!% on everything"
You can even get it mixed to paint match.

I am going to be doing various things around the truck over time, and want to use the same spray. Will be doing punk'n, planned on using the Mopar paint.

I've painted lots of plastic pieces, both with and without the self etching primer. Results were the same whether I used it or not. Just go slow.

I took mine to an auto body shop that used automotive paint with a flexible primer. Did the grill insert and foglight bezels

Yeah that's what I was going for. The bezels and probably the insert, not the grille itself. Looks great.

... Is there only 1 Mopar clear coat?

Looks like I need to steer clear of this one as everyone will argue against how I do my show cars' plastic bits. (and other parts - and Krylon will fade with time - even on metal. )

My plan is to use Duplicolor adhesion primer for plastics, then the Punk'n from Mopar, then the clear from Mopar. This is all small odds and ends throughout, I believe it will look totally fine. Brillo and tack pads and cleaning as is tradition, but in terms of the coats that's the plan.

When it comes to metal parts I will change the primer to etching, but the rest the same.
