My '87 18' SS has caulk/sealant of some type where the splashwell joins to the transom (the vertical side seams). The caulk appears to be a bit older but mostly intact. There is a small crack showing from the splashwell base on one side up about 3 inches after which there is existing caulk of some sort. I need to get that crack filled.
I was wondering which is the best sealant for the job. Would 3M 5200 fast cure be a good choice? If so, should I try to remove all existing caulk up that entire seam or will 5200 work okay over existing? If so should I clean existing with mineral spirits first? I don't know what the "existing" sealant is. It looks like some of the other splashwell joints appears to have a very light bead of caulk as well, but those appear to be perhaps original and in good shape. The sides where the splashwell joins to the transom is where the issue is and it appears to have been done by PO at some point.
Thanks in advance for any guidance.
