I was wondering if anybody has ever tried the gallon of Rustoleum made gray high fill primer sold at Autozone stores for use under acrylic enamel paint?
Follow the directions very carefully as to amount of time between coats. Many of these product should be shot right away or a month later not somewhere in between due to the drying characteristic of the primer
Thanks- that I will do for sure! I appreciate the tip. I don't want to use the 2K epoxy stuff- just the laquer based old-school stuff. Kinda like the old red oxide primer, only in gray high build formula.
I bought some Rustoleum red primer once. Said it was for 'rusty metal'. I put it on clean metal, but wanted gray and red to alternate colors to help me know when I was about to sand through. Well, what I didn't notice was that it didn't say "Sandable" on it. And it was indeed NOT sandable. Wanna talk about plugging up your sandpaper! Lesson learned. I always look for "Sandable" on the label of ANY primer I get nowadays.
Rustoleum plugs sandpaper no matter how long you let it cure. Also, I have not found a topcoat that sticks to it. Black rustoleum is not a stable color. It turns grey after several weeks of exposure to the sun.
Bite the bullet and fork out the extra cash for some good quality primer & paint from your local professional auto paint supplier. DuPont carries a more affordable line of primers and fillers under the Nason name. They are generally 1/2 the price of the equivalent DuPont product but will work ten times better than hardware store paint. They are geared to the hobbyist, and a few auto body shops even use it. Make sure you get a Tech Sheet for each product, or get one from DuPont online. Follow the directions and you won't be disappointed.
The price of paint and primer, even if you buy the real expensive stuff is usually less expensive than your time, even if you are only doing it just for a hobby.
