Finally had enough time to work on the tank on the newly acquired 1978 GS550. Got all the liner out, soaked the inside with metal rescue for a few days, welded up the pinhole underneath and then removed the "bubble" in the paint on the top. When I say bubble, I mean a 2-1/2" diameter bubble! It seems that the previous painter did not take the tank all the way to bare metal, and the bubble was caused by the primer not sticking to the original paint that was left on the tank. It really doesn't look like he sanded the low spots, just tried to fill them in with extra thick (1/8") coat of primer. Anyway...took the old 5" random orbital with some 60 grit to it tonight and this is what I have to work with as I begin the painting process. I've got some Caswell's liner on the way, so I'll probably wait until it is installed before starting the painting. I have to get "all" the old paint off and then some putty before primer, paint and 2K clear. At least I have experience with this as I just finished the second repaint of my GS750 earlier this week. Just waiting to buff the clear on it!
