Brief Description: Remove Proseal from L-Wing Skin
No Step: Scraped Proseal from rib joints using the back end of a bamboo cooking spoon flattened and sharpened like the end of a wood chisel. The bamboo spoon was old and delaminating but the handle was solid and very hard. Worked like a charm. Sharpened it often to maintain the edge and did no visible damage to the aluminium skin.The used MEK and a cloth to rub the rest of the selant from the skin. This presented an original surface as if I had erased time and was ready to seal and rivet ribs. The ribs, by the way, are soaking in a bath of MEK, two at a time, in a chafing dish I borrowed from the wife. She did not mind since they are stainless steel but I'll have to clean them up when done (she doesn't much like the smell of MEK in the garage which was so strong I wore my painting respirator).
The handle of this spoon made a great scraper (Bamboo)
