AP-39 Automotive Paint Primer Grey 2K Urethane Gallon Kit Normal Activator

I used this primer as a surfacer (primer filler) over the top if plastic body filler (bondo). I sprayed 4 wet coats and let it sit over night. Came back the next day and sanded it dry with 400 grit. It sanded nicely! Aside from knowing how much I spent on it I would believe it was a higher end primer. I was able to spray basecoat directly over the prepared primer areas and everything held. The car came out great and I haven't noticed any sinking and it's been over a week now.

Great value

This stuff is great I don't care if it's the first time spraying or 35 years like myself you can't go wrong with this

I've used this primer to custom paint tumblers, the material isn't too thick so mixing it 4:1:1 to use as a sealer with my 1.2 tip has made things so much easier for me. Even though it's not really thick it still covers great.

Good primer at a great price

Works great no issues just do thins coats or it will sag. You get a full gallon and a quart of reducer. Med grey color. Couldn’t be happier with it.

Sprayed way too thick. Had to use a reducer to use it. Wouldn't use again, but it did do its job after some work around.

Easy to spray very easy to sand
