## Questions & Answers

**Q: Can this be applied over dupli-color scratch filler/primer?  should i not to mix different primer brands? but, i did plan to use rustolem paint/clear.**
A: I've never had a problem mixing primer brands in rattle cans but when using the more expensive urethane out of a gun I like to use the same brand.

**Q: want type of  a primert has epoxy in it**
A: you cannot beat this  primer it works great for m and I would not be without it.

**Q: Is primer sealer required if you already used sand-able primer?**
A: Hello primer sealer is for if your primer is going to be out in the weather. Regular primer socks up water and will rust if your primer is over bare metal very fast. Primer sealer does just what it says seals from the elements. Hope this helps Bart 😊

**Q: Can this be used over filler and sandable primer?**
A: As far as I can tell this can be used with body filler. Apply 2 or more coats of primer to the area. It must be left over 24 hours, depending on the temperature & humidity, to completely dry before sanding.

This is probably the best spray can primer ive ever used. I don't even sand it, I lay paint right on top and it comes out really well.

### ⭐⭐⭐⭐⭐ Primer
*by D***Y on October 25, 2025*

This is a great primer. And you can't beat the price!

### ⭐⭐⭐⭐⭐ Works well. Be very cautious where you use though!
*by M***N on November 18, 2025*

This works great after the Rust-Oleum Automotive 2-in-1 Primer & Sandable (I used on a wood guitar project getting professional automotive finish) Two things to note though: 1. If you are using this after the Rust-Oleum Automotive 2-in-1 Primer & Sandable, you SHOULD NOT let the it cure first before putting on the Primer Sealer. It bonds better if you do it within a few hours max. 2. This primer sealer is made up of some seriously dangerous stuff so use PROPER PPE including sealed goggles, not just a dust mask and safety glasses. Well ventilated area or outdoors is a MUST!
