SEM Plastic Adhesion Promoter is rated 4.0 out of 5 by 2.
Rated 4 out of 5 by from Awesome product Used as a prep coat for a polyurethane lip spoiler. Followed all the directions per mfg with plastic adhesion promoter and black bumper coat paint purchased from Eastwood. The finish came out looking as good as factory with no flaking, chalking, or other blemishes after 4 years with regular outdoor exposure. This is my second can to use on another lip spoiler as my friend used up my 1st can with similarly great results on his car.

I need to use a filler primer on an abs plastic spoiler to fill in some small scratches. Do I use the adhesion promoter or the primer first? 

Asked by: Jared
Any raw, unpainted plastic areas should have an adhesion promoter applied prior to any paint or primer. This ensures the best paint job to come.

I have a brown vinyl chair and ottoman that I would like to change to blue or possibly white. What products should I use? TIA

Asked by: Sherry
On Vinyl we would recommend using the SEM Vinyl prep part number 52055z to clean and slightly soften the substrate to accept the color. When it comes to color you can simply pick from one of the SEM Interior colors we sell.

I have to paint a restored 1950 Olds steering wheel. It is the factory highly metalic gray/blue, and the interior and dashboard will be high gloss black. Hence, the steering wheel will have to become gloss black. I need an endurable paint coating.

Asked by: Howie
Of the products we offer the SEM Classic coat in black is the best bet for your project.

I want to repaint a scratched plastic engine cover that was factory painted silver. Do I need this product to apply on top of the original paint, or do I need to sand down to bare plastic?

Asked by: mikeyce
You will only need to apply this if you sand down to the bare plastic.
