Rust-Oleum 251572 Automotive Adhesion Promoter Spray, 11 oz, Clear

Lot easier to apply than I thought. used it before painting a small scratch on my car, and it seems to help the new paint really stick. the spray is clear and goes on evenly. i like that it’s handy and doesn’t take up much space. overall, it’s been a useful product for touching up my vehicle without any hassle. definitely glad i picked it up.

Works well for prepping plastic for paint.

exactly what you get in any brick and mortar store and does what it is meant for - giving a good surface for primer or paint to bite into on a plastic part. Still need to thoroughly wash and clean any new plastic part before using.

Getting this for my car's touch-ups seemed like a good idea, especially since it states it's an adhesion promoter. i used it before applying some new paint near the door handle, and it seemed to help the paint stick better. however, the spray bottle felt a bit cheap and sometimes clogged, which was annoying. the clear finish was fine and didn't add any color or texture, so that was a plus. overall, it does what it promises if used correctly, but be prepared for some tricky spray jamming and make sure to follow the instructions carefully. used at home for minor repairs and it worked okay, but not something i'd say is perfect.

The Rust-Oleum 251572 Automotive Adhesion Promoter is a specialized, fast-drying clear primer designed to solve one of the most common DIY painting frustrations: paint peeling off plastic. It creates a "mechanical bond" on difficult, non-porous surfaces, ensuring your topcoat sticks permanently.

Works great

Why did you pick this product vs others?: Worked exactly as expected. I used this adhesion promoter before painting the interior plastics of my car, and it made a big difference. I had never used one before, but after seeing it recommended on TikTok, I decided to try it. I applied two light coats about 5–10 minutes apart, then painted over it. The paint stuck incredibly well — way better than when I’ve painted plastics without using a promoter. It’s perfect for interior pieces that usually get nicked or scratched after painting. I’m not sure about the science behind it, but it definitely works. Highly recommend if you want your paint job to last.
