Walmart carries it for under $5
The WM stores in my area only carry Rustoleum self etching primer. It's sure cheap but has proven to be just awful stuff. Looks horrible and doesn't stay on parts very well at all.
Duplicolor, Sherwin Williams 988, and Napa 7220 (same as SW988) have all worked well for me.
Wow! I may have drive off the mountain and find a Walmart! Yesterday I felt like I was getting to the point on my empennage that I'm going to have to make a primer decision. I found out last week that I can no longer get my tried and true Variprime here, so I went to our local NAPA store yesterday to pick up a couple cans of 7220 just to get started, and all they carry is the Duplicolor. But... it was $9.49 - over $10/can out the door!, so I just bought one can for a trial run. They can order the 7220, but it's about $0.50 MORE per can. The price difference wouldn't sway me but if the Duplicolor works as well, and it's available off the shelf, that's the way I may go.
Some of the NAPA stores in my area have 7220 on sale for $5.99 right now. Check in your area -- they seem to do this on a regular basis, but not at every store. www.napaonline.com is an easy way to comparison shop between stores.
A year ago it was $5.49, so not quite certain why they raised the price by 50 cents in a no-inflation environment...
Hi Everyone,
I'm new and still in the planning / lurking stage. I must admit I'm very confused by the whole priming question.

Why would ANYBODY go through all the pain of the Alumiprep 33 / Alodine 1201 multiple step cleaning, washing and priming with a spray gun process if simply spraying the parts with Duplicolor, SW 928, NAPA 7220, et al from a rattle can will suffice?
As I'm trying to make up my mind about tackling this project, one of the things I don't think I'll like is having to prime all the parts. Especially when lots of folks say priming isn't necessary at all!
Is the rattle can approach a good middle ground? Not as good as the multi-step processes but better than not priming at all?
Finally, what prep process do you all use for rattle can priming? I think I've gathered you still have to clean up the surface. Is roughing it up and cleaning it with a solvent adequate?
Thanks for all the great info so far!
