Cab over repair with picture

About three years ago the bottom of the over cab overhang on the passenger side separated from the sidewall about 1 1/2 inches. Not wanting to tear into for a rebuild but wanting to save it here is what I came up with. Inserted the nozzle from a can of Dap expanding foam adhesive as far inside as I could go all long the separation had to two ratchet cargo straps around the cab over and as soon as I had filled the area with adhesive I tightened the straps down. With disposable rags soaked in acetone removed all of the adhesive as it came out of the gap that was now down to a 1/8 of inch. While still strapped drilled a series of 5 holes up about 2 inches from the bottom following the curve of the cab over. Then ran in screws with fender washers painted to match the cab over. After a full week took the straps off and it held and has held for about three years.
The one problem I have had over the years is sealing that 1/8 inch gap every type of caulk or sealant that I tried would crack. Several months ago I scraped all of the old sealant off cleaned it with acetone and applied clear Gorilla tape. It is has held up better than any sealant or caulk has.
Do not get confused with clear Gorilla tape and Clear Gorilla sealing tape.
