## Questions & Answers

**Q: What kind of paint should you use to tint?**
A: I use PPG products so I stay with same brand

**Q: How long is the shelf life?**
A: A year. If place on a cool environment , 80 deg and dry with lid sealed it will last a little bit longer. Requires regular shakes up to keep  chemicals suspended.

**Q: can you paint acrylic urethane paint directly over this ?**
A: Yes. Even this primer can go over epoxy seal and still acrylic urethane can be used over.

**Q: Can you apply it over  properly prepared acrylic lacquer without a problem?**
A: I have successfully applied this over Lacquer. The panels were dry and cured for years, and the paint was sanded with 220 grit before doing so. I believe that if any surface is cured long enough and sanded correctly, this primer will work over just about anything and everything.
