I have read that the Akzo primer is primarily used on internal surfaces and must be heavily scuffed or sanded prior to top coating. My question is whether any one besides me thinks it is a good idea to epoxy prime the exterior of thier aircraft?
I work for a large aircraft manufacturer who epoxy primes every square inch of the entire aircraft using a similar Skydrol and solvent resistant epoxy primer that made by PPG Deft. This PPG primer is thicker, heavier and does not lay down as smooth as the Akzo, but it is used to seal and protect the external surfaces prior to the aircraft being outfitted and painted with a customer's specified paint scheme. The painters simply scuff sand the primer than apply a primer coat that is compatible with the top coat.
The are several reasons why I am considering priming both sides, the primary concearns are as follows:
1: S.E. Georgia is HUMID! and even Alclad aluminum will corrode inside the hangar or garage.
2: I have extremely corrosive skin oil and can rust steel tools or corrode bare aluminum in a matter of hours.
3: The exterior of the aircraft will be protected During the time between completion/first flight untill I paint it, or have it painted.
4: Epoxy primer has a tendancy to fill small voids such as areas around rivet heads and countersinks, which makes the final finish look a bit nicer.
So every one has an opinion...so lets hear them!
