Adamm! Great to hear the Eastwood stuff worked as advertised. It SOUNDED perfect for what I was looking for, now tell me whats the best deal I can get buying that stuff? SIRELAND, yes, I want to make sure the rockers are cleaned out- to prevent any gunk from holding moisture and to make sure the rust sealer adheres. Again, this car is garaged year round and will only be out on a limited basis in summer. I was considering cutting a hole on the top of the rocker under the sill plate so I could spray it out before sealing; not sure the openings at the pinch welds on the bottom will be larger enough to spray in or drain any gunk out?
