[QUOTE="Weldorthemagnificent, post: 474185, member: 22139"] Don't use 6061 it will corrode. 3003 is ok and I use it because it's readily available. 5000 series is best if you can get it. For a bolted or riveted patch, prime both surfaces first so that the sealant doesn't cause corrosion in between. For a welded patch it doesn't matter because you don't use sealant. Prep surfaces with a 50/50 mix of vinegar and water and a scouring pad. Sent from my CLT-L04 using Tapatalk [/QUOTE]
