I'm closing up the rudder and need to adhere the wedge to the skin. I primed (Akzo two-part epoxy) the inside of the skin before I realized there is a specific instruction to leave the skin common to the wedge bare.
I've decided to use Proseal (AC-232-B2) as the adhesive. Should I sand all the primer away or can I get a good bond by just cleaning then roughing the surface with either ScotchBright or sandpaper?
If it's ok to bond over the primer, what cleaner should I use? Acetone? MEK? Soap and water only? IPA? I've heard that if you let whatever solvent evaporate it'll cause a real problem for bonding.
Anybody have any advice?
