Evaporust gel completely ate away the rust on second treatment. Took awhile to scrape and clean everything. Decided to sand the A pillar and dress up the corners. There is one rust through hole about 1/8" diameter in the rain gutter. I will weld that up and grind it down tomorrow evening. I taped off and brush applied epoxy primer in the gutter area because i could get it in there better and thicker this way than with a spray gun. When its dry i will tape it off again for the out of date aircraft seam sealer. I plan on priming over the seam sealer.
