If you think the loaves and fishes was a reasonable miracle, wait 'till you see what FSR does to rust on the hull (or mot other plastics including Dacron). Always use the gell, though, never,NEVER the spray bottle. Apply the gell with an aptly named 'acid brush' which you have trimmed the bristles down to about 1/4". Put it exactly where you want it. The gell doesn't wick into places it shouldn't go...If it does, the rust will come back with a vengeance
