I've been thinking of another use for 5200 though. I have numerous holes in the floor of my 19' FG OB. The plywood floor is getting weak from water ingression in the past. Want to prevent more rotting plywood.
Thought of plugging the holes w 5200. But I think they may come loose over time. Thinking of putting a 1" dia pice of AL or SS over the 5200 or even a Quarter. Could catch a shoe on a quarter though. Another possibility would be to put a bit of FG cloth on top of the 5200. Do you think it would "wet out"?
Also when I install the seats later I want to glue pieces of wood or aluminum channel to the floor and attach the seats to the channel w bolts or screws. I'm thinking of Sika Flex for that.
Eric, I guess it depends on whether you want to patch or fix. If patch, 5200 will stick like heck to solid wood and never come loose, but you'd have to be sure you were anchoring to solid wood. I think I would rather fix by saturating the punky wood with epoxy thinned with MEK, a.k.a. penetrating epoxy, then patched with wood dust thickened epoxy. If a couple extra pounds isn't an issue, then a single layer of epoxy glass over the outside of the hull up to the water line will make the repair permanent.
