Default Which self-etch rattle can primer do you prefer?

For those out there that have used self etching primers in rattle cans, I'd like for you to vote your experience... I'm getting ready to start an empennage kit and thought I'd see what the majority of users are using.

Update... I'm seeing a lot of "Other" votes and mentions of Duplicolor. I'll see if I can add that to the poll.

I voted Napa's primer only because it is what is available to me locally, not because it's best. Best as in durability is likely going to be a two part epoxy.

I have used both NAPA and SEM, I liked SEM much better, it goes on much smoother and dries very quickly. Also very durable, just little more expensive than NAPA

Default Primer

For our empennage we started out using Dupli-Color self-etching primer. The stuff is great but expensive in large quantities (and expensive to ship since it's HAZMAT). It dries very quickly and you're ready to rivet just a short time after you've sprayed it. We found the best deal for it at NAPA Auto Parts.

I used Har-Hyde as that was popular with the guys on the RV-list and local builders way back in the late 90s when I started my plane. I used it on interior peices as I was building. Everything got a coat of epoxy primer and epoxy top coat (PPG Concept) after installed. No signs of wearing, pealing, or cracking after 5 years and 450+ hours of flying.
Exterior all done with PPG self etching primer, epoxy primer, and epoxy top coat. Paint is bullet proof.

Current favorite is Duplicolor Self-Etching from Advanced Auto - $5/can, does a great job, goes on easy.

I used the Napa rattle can very happy with it. The paint I sprayed on 8 years ago looks the same as the day it went on. the cockpit and baggage area I top coated with PPG concept paint, the two stuck together very well. As for any primer and paint, prep is everything. but there is no question a two part primer is much more durable and can Handel the fuels and oils.

Mar-Hyde from a can is inferior to Duplicolor Self Etch you can get at any auto parts place or places like Wal-Mart. I discovered the Duplicolor about 1/2 way thru my build and it is awesome stuff.

For large parts and skins, I used the waterborne primer from Stewart Systems. This stuff is awesome once you learn how to spray it. Best part about using it is the cleanup!

My vote was for SEM.

Whichever you use, get one of these handles. It makes applying it much easier.

The other tricks I learned to put it on smoothly was to heat the paint by placing the can in front of a small space heater and wipe the nozzle every few passes.
