Vinyl and plastic spray paint aid

Hey guys. I just had me a can of SEM spray paint made in red to match my interior. They also sold a spray can of something to aid in the paint adhesion but it was $40 bucks. I will be painting some plastic trim and then maybe a black to red dash pad, both new parts. Do I need to do any special prep or buy any type of primer spray? Is so what and where? Thanks

 

You’ll want to use a wax and oil remover/ prep like SEM PREP SEM solve

...and hope no one used any of those silicone dressings on pad...

 

YES YOU MOST DEFINITELY NEED A CAN OF "BULLDOG" ADHESION PROMOTER

 

Clean with Alcohol,..apply MIST coat of the promoter then go straight to paint,..xont let the promoter sit more than a few min at most b4 topcoat

 

Dash pads don’t need adhesion Promoter if paint is lacquer based. I’ve done several. Dash paint must be O gloss as in flat. You are making a massive mistake if it’s not flat. It will glare like hell. Poly plastics like kick panels DO need the promoter. Consoles and other hard plastics don’t need any promoter with lacquer. Don’t use any enamel paints on plastics

 

I have a GM service bulletin that shows how to paint all types of plastics used in GM cars.

 

Adhesion promoter certainly won't hurt when using lacquer,....I myself don't use spray cans,...being a professional auto body and paint tech with a mixing service I use solvent based base coat,..used as i described above,..you can't scratch it off if you tried,..but if using spray cans yes absolutely use lacquer,..biggest thing is a very clean surface and a light first coat to grab the others

 

Sem may even have a promoter In their formula,....some of thier products do
