Soft wood under FG lip

[Biasdr]

Just prepping to use RotFix a 12"x5" soft spot under the rear window. A consderable section is under the fiberglass lip. Any problem with drilling holes through the fiberglass so I can syringe the epoxy in the hidden wood? Thanks in advance.

I used GetRot on a wooden boat once, I think it's similar to your product. It worked well, but a year later, the rot had spread past the encapsulated area and I had to replace the board.

You have a somewhat different situation since your wood is surrounded by fiberglass, and it sound like it would be a real hassle to replace. But be sure to keep it dry after you treat the wood. If that window is still leaking, the rot will continue to spread.

Can you post a picture or the area you plan to repair. At a minimum the wood needs to be very dry in order for the epoxy to penetrate. Check your instructions but you probably need to get the wood to 20% moisture or lower. I repaired a lot of floor rot on my Scamp. Most of it was accomplished by cutting out the rotted wood and fiberglassing new wood in. I almost used git-rot on one section however using a blower for a week I could not get the wood to even come close to 20% moisture. I wound up just cutting that section out and had a sound repair in a few hours.

GetRot and RotFix are expensive and for a large area I'm thinking you might be better off to cut the bad part out. I have seen information about using epoxy resin thinned to make a similar but less expensive do it your self product.

I should have known initially to be more specific and clear. That's why I love this site. Always great analysis and advice.

1. Too difficult to cut out as it's in the fiberglass lip area. It's on the extreme back edge of the burro.
2. Area is "6 out of 10" for deterioration. Not critical but clearly soft.
3. Wood is dry and window no longer leaks
4. Already have possession of RotFix

My question should have been "if I drill holes through the fiberglass and inject RotFix will the wood bond permanently to the fiberglass, making separation impossible if I ever want to replace the floor."
Thanks guys, for the interest and help.

When the trailer was built, the fiberglass was bonded to the wood with epoxy resin. RotFix is basically very thin resin, so it would bond the wood and fiberglass together maybe not quite as strong as the original. Separation at a later date would not be impossible. Hopefully unnecessary, but no harder than when new.

That's what I needed to know. Thanks folks!

Replace the wood with epoxy coated coosa board
