Hello,

I just got my 68 Mustang back from the sand blasting (by a professional company) and it looks like they painted the whole body in a red-brown primer for corrosion resistance.

I would like to paint my complete engine compartment with the Glossy Black RustSeal, and I was wondering if I had to lightly sand the existing primer with 320 grit paper or not prior to spraying the RustSeal?

Of course, everything will be cleaned with degreaser afterwards.

For info, I don't want to sand everything to bare metal!

My other question is: do I have to thin the RustSeal if I spray with an HVLP gun with a 1.4 nozzle?

Thanks for your support, great products so far!

"I was wondering if I had to lightly sand the existing primer with 320 grit paper or not prior to spraying the RustSeal?"

Yes. That would be great.

"do I have to thin the RustSeal if I spray with an HVLP gun with a 1.4 nozzle?"

Yes. Usually 5-10%. But I also have known people who do not thin it at all. But we do recommend 5-10% with KBS #1 Thinner.
