Review: great spray pattern, works well with plastic, and hides blemishes. - used this to paint some chrome trim around the front grille of a 06 Acura TSX. It had lots of rock chips and dings so i wanted a high build primer to fill it in. i didn't do much sanding before since it was going to get chipped up again after a month of driving but the SEM primer filled in nearly everything smooth. the best part is they use a great spray nozzle. did 3 coats and every time i used it it was a nice predictable even spray pattern with no splatter. came out perfect, easy to sand, and easy to add a few extra coats in spots that need more build up. i had no intention to make the trim piece perfect before paint but it ended up perfect thanks to this primer.
Review: Excellent - The good stuff!

## Questions & Answers

**Q: What's the difference between this product and sem self-etching primer?**
A: The high build primer is used under the top coat, to fill any scratches or minor imperfections while finish sanding, and self-etching is used only on bare metal, under any body filler, or other primer.

**Q: Does this stick to silicone?**
A: NOTHING sticks to silicone...or...nylon.

**Q: How well will this adhere to existing finishes?  I have some bare metal and some areas of existing paint and other primer.**
A: As long as you sand the paint and medal with at least 220 grit sand paper fine. I have been using it on fiberglass/paint. It will show you the high spots and lows. You could also use a contrast material to make sanding easier to get your smooth finished product. Hope this helps.

**Q: How long does it have to dry before recoating?**
A: It  is mainly depending on environmental temperture. Watch the first  coat, when it flashes, it is ready for the next coat. A  little extra wait wont hurt.

### ⭐⭐⭐⭐⭐ Best primer I have used on my latest projects.
*by J***Y on January 18, 2017*

I was looking for a new primer recently and came across a post a friend made on finishing a helmet project for some prop work. He said he tried out a new primer and loved it. So I asked what it was and ordered a can and "OH MAN!" Fantastic primer. Yeah it is a tad bit on the expensive side but I use it to finish models and 3d prints as it helps fill seams really well and saves me a lot of time sanding and finishing. So that makes it worth it to me. Fantastic hold and the grey color is perfect for building on top of. This will be my base primer coat on everything going forward.
