So, I sandblasted the Herter's parts, then painted the underside with zinc chromate to hopefully prevent any future corrosion issues (use a respirator if you paint with this stuff!)
Now I'm ready to put it back together and I'm wondering about sealing the bolt holes. I don't know what Herter did from the factory, but I'm fairly sure that they didn't use any sort of RTV (which i found underneath when I took it apart.) I was thinking about making gaskets out of some thin rubber to try and keep them from rubbing against the fiberglass, but honestly I don't know if that's needed. I might be able to get away with using just a neoprene washer around the bolt holes
Pretty sure that the transom brace and the transom had a rubber gasket between them for vibration.
I could see stuff getting stuck underneath the rubber, or the rubber sealing the entire interior bracing so that any water that does get held in stays inside that area.
Anyone have any thoughts on the matter?
Transom brace and transom, the notched portion is the part that bolts to the transom.
