Stopping a stress crack dead in its tracks

Recommended Posts

jklein

I have one really small stress crack near my tower mount that's gotten a little bit bigger in the last month. It's so small it looks like a hair that's about 1/2 an inch long.

It's not a big deal, and I don't really need to fix it right away, but I want to stop it from spreading if I can.

Any suggestions for stopping it? I was thinking super glue near the termination point, but I don't want to make it look worse. I'll also go re-visit the tower mount to make sure there's plenty of back plating there.

Don't know if it appropriate on the fiberglass of the BU but in past years I have stopped stress cracks from running on the plastic parts of my motorcycle and 4-wheeler by drilling a 1/8" or a 1/4" hole at the end of the crack. Keeps it from running but now you have a hole to worry about / fill in.

BadDog, that would be a good idea if the fiberglass was cracking, but it's probably just the gel coat, and I don't think I'd want to drill all the way through the fiberglass just for that? :)

I agree, I never like to drill into the fiberglass, but if the gelcoat is cracking what will crack next? If there is enough stress to crack the gelcoat will it crack the whole enchilada over time?
