I am building a RV8 quickbuild that sat in a hangar in Pa for about 8 years. The surfaces of the wings and fuse have light white corrosion. I just finished the tail so It will still be awhile before I get to the priming stage of the wings. I wanted to do somthing to clean them up and protect them in the mean time. I have had many suggestions from polish, alodine, prime and just wash with dawn and build on. I talked with a corrosion guy at osh this year that said to alodine them so this weekend I tried and the came out bad. Here is what I did and the pics show what I got.
1 Washed well with a warm water/dawn solution towl dried.
2 Washed with Aluma Prep mixed 1:3 with water let on 3 mins rinsed
3 Found some spots that didnt come off and ended up scotchbriting the whole wing. ReAluma Preped and rinsed. Made sure water didnt bead up.
4 Let dry completely overnight in garage.
5 Wiped down with full streangth Alodine let sit 3 mins rinse.
The thing looks like some tie die shirt from the 60's I Re did the aluma prep wash and alodine and it looks pretty much the same. I'm thinking let it alone till primer. I have the other wing and fuse to do though. Any suggestions?
