Hey baddbob its actually a 92 camaro
Today I poured some water into the water channel and nothing came through so I think its getting caught up in the back of the wheel well. I am sure the seam sealer has failed.
Hmmm so epoxy primer and then some urethane seam sealer if I am able to open up the seams. I will give opening the seam a try. It looks really challenging since there are 3 walls to try and open up but if thats possible it makes sense.
Also forgot to memtoin that the rust has some permatex rust blocker on it (put it on there temporarily) and that is why its black.
