fiberglass gurus, need advice.

Totally green on glass work here. Looked through post and stickies but did not see much stuff like what I have. I have two sections of encapsulated wood where the wood inside has broken down. These are mounting points and need to be pretty strong. The glass on the exterior (underneath) is fine. My thought are to cut out the tops, leave the sides, install new wood then glass it with several layers of resin mat, the wood is about 3/4 thick. I’m probably going to use a glass kit bought at the auto store, because I only have two small areas to do. unless that’s a bad idea. Any thoughts, suggestions welcome thanks in advance

I would not buy a kit from the local auto parts store or big box store as it has most likely sat there after it's expiration date and it won't have 1708

Cut out the entire chunk of wood (just like removing stringers)

Grind the tabbing back 4-6" or more.

Pick up a gallon of resin and MEKP, 2 yards of 1708, 3 yards of CSM and some fumed silica

That will get you all the supplies you need to do the job right

If you are going with wood reinforcement, cut to size. Mix up some PB and bed the wood in, then tab in place with 1 layer of CSM, and 2-3 layers of 1708

If you are using aluminum plates embedded in the layup, drill a bunch of 1/8 holes to lock in places, then glue in with PB

You will use the same resin and a single layer of CSM and a layer of 1708 on your spider cracked panel

Grind down with 40 grit the cracked gel and past first layer of glass.

When cured, fair as needed. Since this is a side car, Bondo brand is acceptable

Thanks Scott for that info, plenty of detail to get this done. Found a local supplier that has what I need.

As an alternative to wood, you might consider some Starboard roughed up with some 50 grit.

Apply some plastic drop cloth pressed down over the area while the resin cures for s smooth finish.

Resin doesn't stick to Starboard (HDPE)

I know, but it may not be an issue for a mounting pad

I have some one inch thick plastic here. The stuff they make modern toilet partitions out of. I believe it’s all recycled plastic. Has a kind of waxy feel to it. I should do a test and see if resin and cloth will stick. Not overly concerned with super smooth finish. The front mount will be under carpet, the rear in a compartment behind the seat.

Got this thing done. Maybe some pinstripes in the future. The glass work turned out pretty good for first time. Should have took pictures. It’s definitely strong enough. Many thanks to Scott Danforth and tepnfield for the help.
