## Questions & Answers

**Q: Is this compatible with a urethane basecoat and clearcoat?**
A: Self etch primer is for bare metal. You should seal it first with a top coat of sealer primer before basecoat.  I have put basecoat directly on it with no problems though.

**Q: Will this stick to plastic ?**
A: I would probably use SEM Flexible Primer Surfacer on plastic.

**Q: Should this product be used on bumpers before spraying with SEM black trim paint?**
A: I'm not an expert but I use this product on bare "not chrome" metal. If you're talking about a chrome bumper I'm just not sure if this product would actually "etch" it.  That's an interesting question though.  I think you should call SEM or Eastwood products and ask. Eastwood has a lot of products and experience with coating different materials. Check their website out. I'm interested to hear what worked for you so please let me know.

**Q: why is the 2 pack more expensive than 2 single cans combined?**
A: I bought 2 and 4 packs cheaper 
Just have to search
