I mixed up a batch of resin and applied that to the seam, held it in place with a piece of aluminum foil. After forcing the resin back into the crack with a brush I laid the foil over the top and pressed it in with my finger.
We had a bad storm today 60+ mph wind gusts and 3 inches of rain. Nothing came through the belly seam.
I sanded that first coat tonight and now that I have the silica and mat I cut up some fiber from the mat and made a batch of stiffened resin. Applied the same way, with foil. This was to fill in the depression and give the seam some strength.
Front window frame leak has been fixed. I have a tiny leak where the rubber "D" seal along the top of the opening window has come unstuck.
For those not familiar with these old style Scamp windows
they have an aluminum frame riveted to the shell, the part of the window that opens hinges at the top and has prop arms to hold it up in the open position. The D seal goes between the aluminum frame of the panel that opens and the window frame attached to the shell. The seal gets squished between them when the window is pulled in and latched.
My seal just needs to be put back where it belongs with a little adhesive.
I also have silicon caulk glazing on one window that no longer is adhering to the Plexiglas so that window allows water into the window frame. Rains hard enough and the frame can't drain fast enough so it overflows to the inside. Todays hard rain left a spot about 1/2 the size of a dollar bill on a bench seat. Have the silicon to re-caulk that.
Really need to try and locate the actual glazing strip that locked the Plexiglas into the frame and sealed it. But will caulk for now.
