How to Custom Paint a Car : How to Mix Primer to Paint a Car

Hi I’m Doug. I work with twenty great guys
in St. Louis at Doug Jenkins Custom Hot Rods, and we’re going to do some work for you today
on Expert Village. Okay now we’re going to get ready and mix some etch primer. Tony’s
putting on the clean suit. And etch primer is maybe the most important thing you can
put on the car for its protection. It’s a two part system and it seals up the steel
and satisfies the steel’s desire on a molecular level to rust. Steel is unstable, it wants
to grab oxygen out of the air and that’s what makes it rust. This stuff here, this yellow
goop he’s mixing up, you spray that on there and that settles the steel down. It satisfied
its desire; it’s electronically, I guess, unstable. And it’s grabbing oxygen out of
the air or water. It grabs this stuff better. And we don’t mix a whole lot of it; you put
it on really thin. Like if you can see it, you’ve put too much on. And if you put too
much on the paint won’t, it’ll bleed right through the paint and ruin the paint. We’ve
got a few places where there’s sand-trough?s on the impala. And he just wants to spot them
with the etch primer, so that we have good rust-proofing on the car.
