PPG DP-40LF two part self etching epoxy primer. Use PPG DX533 aluminum cleaner with red Scotchbrite pads to prep the aluminum. Rinse with a lot of water, let dry then prime.
Very tough, scratch and solvent resistant product. I use the same primer with PPG concept base coat clear coat for the finish paint. PPG concept is very forgiving to the amateur painter working in a makeshift paint booth.

Subject: primer segestions
I am looking to find a very easy to spray and manage primer. I do not want to acid etch and Aldine then prime. So I am looking for a simple primer that I can spray right on to a scuffed part with reasonable protection. I am in northern California so no real wet environment at all. Plus I have a have to park it in.
What would you builders recommend.
Thanks
John

DP40 is NOT self etching. It’s a catalyzed epoxy primer that can be used as a sealer depending how it’s mixed. Great stuff though.

well I am one that says right on! That is what I did and the primer has held well. I did use the 988 and funny that the self etch actually doesn't do well with alclad and comes off pretty easily. Wash primer no problemo as our governor would say!

I have had great results with SEM primer. I studied primer a bunch until I landed on Randy Lervold's site and took his advice: http://www.romeolima.com/RV3works/Airframe/airframe.html#Primer Randy is our EAA Chapter 105 president. I use the spray cans with a clip on spray handle for convenience. Cost is a bit more then quarts but, easy clean-up and pro finish. I do not scuff with scotchbright choosing instead to preserve that layer of added factory protection, I just wipe my parts with lacquer thinner and shoot them. Last thing, I prime each part before assembly adding the layer of protection where is is needed most in the future.
I know there are at least 20 guys that are reading this and thinking wrong, wrong, wrong.
Best Wishes, good priming,
Paul Grimstad
