    Long time lurker here

    I purchased this boat in 2012 from someone I know. I was told that the stringers and sole had been redone recently, and the engine had low hours and was in decent shape, so I thought I was getting a deal. It mostly seemed in good shape at that time.

    Just before the next season, I found how bad it was. It turns out the guy that did the work did an incredibly poor job. The plywood used was of low quality, and was coming completely apart in places like sheets of wet cardboard, or worse, mulch. The tabbing used was the absolute bare minimum (one layer, no fillet, and not even along the entire length). He also didn't touch a few areas, notably the transom (which was wet and starting to rot). On top of this, no weep hole was left to the rear bilge: water would collect in the bilge and never drain.

    Not that any of that matters now. I've been working on it since, and have really been picking up the pace as of late. Right now, I have the transom glued together, and most of the other wood pieces cut out. Nothing installed yet. Most of the sanding is done. I'm using good quality plywood and epoxy.

    As I've come to the end of all the sanding/grinding, I've noticed the fiberglass itself shows some signs of water damage. The fibers are visible within the resin. Ive sanded these down in a couple spots (almost to the gelcoat), with the intent of replacing the fiberglass in these spots. In one place I've sanded down, you can see this follows where the wet stringer was. What I am wondering is if I should try to continue doing this, or is it "good enough" to leave as is. On one hand, I want to "do it right", but on the other, it IS and old boat and never going to be perfect. These areas do not seem to be coming blatantly apart or anything, and I will be reinforcing them anyway with glass and stringers, plus the added waterproofing of epoxy. What do you think?

    I have sprayed liquid on these areas in the photos to make them stand out better.

    This is just the old chopped strand matt from a chopper gun that was sprayed over the top of the woven that did not have sufficient resin in it to wet out properly Its been there all this time so I wouldn't worry too much !:p

    I would look at using SpaceAge Thermo-Lite Board. It is lighter, tougher and doesnt absorb moisture and will last forever. One time worry free install.

    Really, you've joined today and dropped 6 nearly identical plugs for "Thermo-Lite", but the site has no real data other than it being a 9 pound urethane foam. How about some pricing compaired to similar core products. Additionally some physical properties would be nice, as well.

    Par , it is my understanding that Thermo Lite is Coosa's biggest competitor , and to tell you the truth i have quit using Coosa years ago due to the fact that Thermo lite is much cheaper, offers a higher density if needed , and there is always that chance that you can purchase second's / scratch & dent . Just for the record lol.........i am no way affiliated with Space age or Thermo Lite .
