West Systems bonding epoxy
#11
keep in mind when using epoxy that it relies 100% on mechanical bond. in other words any surface that has epoxy applied it needs to be 100% sanded or ground, not just cleaned over lightly by hand but thoroughly sanded/roughed up. the percentage of bond strength is directly proportional to prep.

I totally agree with Dave. You would not be able to "feel" any flex in 5200 although it has some elasticity. A light tabbing of glass with epoxy or whatever is just a bandaid and will not withstand repeated cycles of slamming. On my personal boats that I build, the deck and hull sides are one bonded laminate with four to six layers of lamination on the outside and on the inner side. They are not going to delaminate under most foreseeable conditions. Many manufacturers just do not laminate proper scantlings no matter what the designer specified. Limited tabbing will help, but in my experience 5200 will be superior if you do not have access and do not do stepped tabbing. I will let Dave weigh in on this. Good luck. Bob.

one of the problems with injecting epoxy into a blind void is you have no way of knowing it's condition and also no way of doing any sort of prep. For a standard marine shoe box joint I would have to agree 5200 is probably best if you cannot do a fully tabbed joint.

my scarabIII was done like that except they used a piece of rubrail on the inside. was actually a pretty good idea and seemed to give it some good clamping force

I used the epoxy to fill the gap and bond the previous tab back to the hull. The poly was applied to the top side of the tab to the hull. So aside from some very small spots where the epoxy oozed out, the polyurethane resin / chop mat was bonded to existing polyester surface. I took it out into some pretty nasty stuff over the weekend and the repair looks good. However time will tell. Again, Aside from using the Six10 I don't think my repair was really much like the OP.

This is a good place to buy any Plexus adhesives, less than half the price of jamestown and they actually have stuff in stock. http://www.compositesone.com/
