Epoxy vs. 5200

[Boris]

Only thing about 5200. It will harden and let go in a few years. My friend just blew out his scupper tube after 2 years of use.
Since he used no foam in his tray the 5200 was the only thing holding the tube in place so 2 years isn't that bad after all.

I was actually worrying about that when I was considering no foam - what happens to all the unsupported pipes? I can see how a scupper in particular would work its way loose.

He learned his lesson and is glassing it in right now.
5200 may be a great sealer but not much of a bonding agent.

Windshield glue on the other hand holds strong.

the 5200 remains flexible.

the epoxy mixes do not.

I would use the 5200 on things that might vibrate or move around alot.

I agree, the 5200 I have used has stayed flexible.

Boris, I dont think your friend did a good prep job if it let loose.

Has anyone ever used The Right Stuff? It's made by Permatex. It's some super tuff stuff, SeaPoo's put pump shoes on with it. I have used it in the past, but may use it again when I seal my tray area.

Bostic 1100 or 3M5200 fast cure, DO NOT GET THE NORMAL CURE!!!!!

epoxy is not for sealing thru-hull fittings..

I still got all my foam so I think I'll be fine. Plus the hole the pipe is in on the firewall is tight to the pipe and the rear hole is tight to the scupper. 5200 it is, thanks for the feedback.

No. Use epoxy thickened with something like cabosil for filling the bondline.

or microballoons

or microballoons

I wouldn't use micro balloons - they are used to make epoxy sandable, and reduce its strength. For reinforcing use cabosil and glass over the filler while it is still wet - that way you can get the filler to conform to the contour of the fiberglass, and you get a very strong bond when it all cures together.
