Just to keep the records straight, who can help me in identifying good/bad metal reactions...probably for the metallurgists out there :) We know that some metals interact overtime, creating more or less a weld, so that its impossible to get out a bolt for instance because of corrosion. Very important to know if you're changing bolts, screws and shims on your DeLorean... Stainless + Stainless = Stainless... Steel + Steel = Steel...or rust over time Stainless + Steel = ? Stainless + Aluminum = ? Steel + Aluminun = ? Stainless + Galvanized steel = ? Steel + Galvanized steel = ? Aluminum + Galvanized steel = ? Best wishes Stian Birkeland Norway VIN # 06759
