Brushable primer

[cgroves]

For my Radical build I’ve decided to only prime internally along where surfaces overlap/join. The plane will spend most summers on floats but will see very little, if any, salt water. It looks to me that to assemble the pieces with the primer still wet it would be a lot easier to brush it on. What’s the best two part epoxy primer that can be applied with a brush?

In the past, Murphy has always recommended the Stits EP-420 epoxy primer. That said, many have used other things. SEM makes a good self-etching primer and NAPA Auto has a good one as well. There are other Epoxy primers, with varying levels of difficulty in application.

I used the 420 as Jerry mentioned.
Make sure to dip every rivet and pull the rivet when it's still wet. Wipe off any excess before it dries or it won't come off

Acetone works good to clean it all up
