    Fiberglass repair guide ready for review.

    Ok, all done. Sorry this is so long, but I tried to write it so someone with zero experience could have a good chance. I think I broke the picture uploads though. Cutting and pasting from the one long post, they showed at first but turned into that link text when posted.

    8 Potential Problems Finding More Cracks. ( Last picture doesn't seem to be uploading properly, even after I reduced the quality. ) This happened to me as I was cleaning it off to get it ready to spray. As soon as I wet the area with some wax remover, some more cracks appeared above what I...

    5. Prep Masking. You need to clean the area with acetone, mask it, and get your materials ready. Mask the area, taping just outside of the ground area. Also lay down masking paper or plastic on the floor and anything under where you will be working. Glass. Get your glass ready. Tearing the...

    Fiberglass Repair Walkthrough ( Mods, since this is so large, I'm going to try to post roughly half of this as a reply. I don't know how well it will work, so please wait until I'm done before commenting.) Introduction I've been repairing boats for almost 12 years at this point. I've only...

    82 Starcraft MR 180 floor, slight refit and leaks

    It would prevent the fiberglass from bonding because the wood is already saturated with a repellent material.

    Sorry I'm taking a bit, but I haven't forgotten. As of a few minutes ago, my walkthrough is about 8,000 characters over the limit. That's after I decided to do the body work seperate and did a bunch of editing. I'm thinking the initial post will be half, and post the rest as a reply. Not here of...

    82 Starcraft MR 180 floor, slight refit and leaks

    Makes sense. When we do it, it's always on the trailer. After our attempted fix the boss will sometimes float it to check. Haven't done one in a little while though.

    Boat Battery Questions - Cranking

    I don't know much about batteries or electronics, but I asked my supervisor about the batteries for boats not too long ago out of curiosity. His explanation, the point of a deep cycle marine battery is that they have a higher capacity. They are mostly to run all of the electronic accessories...

    82 Starcraft MR 180 floor, slight refit and leaks

    I don't know about the varnish, but there shouldn't be any need to stand the pieces on edge. The wood should wick the liquid in. You'll probably need to wet the edges a bit more than the flats though. It would also be good to round the corners a bit. A sharper corner has less surface area and...

    I'll take pictures of materials and tools at work tomorrow. I do have a small spot that I need to grind and glass on the current job, but it will probably be Monday before I get to it. I might wait until then so I can get some in progress pictures.

    Looks like the how to has it covered. I'll still write my version if you want, but I have different experience and will have some conflicting advice. It might be best to follow one set of instructions. Up to you.

    Transom replacement.

    I'm not familiar with the product numbers, but from a quick google it seems that 1700 is what we call byply, which is a biaxial weave with a thin layer of csm stitched to the bottom. 1708 I think is just the woven strands, or what we call roving. The roving by itself wont give a good bond to...

    If you want, I can try to write a more thorough walkthrough for your specific job tonight. There is also a more general how to on fiberglass somewhere here, but I couldn't find it quickly.

    Transom replacement.

    It would need thinned quite a bit with acetone, but would be doable. I know acetone isn't ideal, it can interfere with the chemical bond, but practically it's fine. I've never had any issues once I finally got a feel for everything. If you don't want the mess of spraying though, I think I...

    Transom replacement.

    I was taught that the biax doesn't bond well by itself. It's strong because they are long continuous fibers, but the weave doesn't let them get into the surface scratches very well for a mechanical bond. I've actually peeled off bits of roving by hand that didn't bond well. I would suggest...

    Mounting outboard.

    Nope, bolts are plenty. Put a bead of silicone around the washers on both sides.

    Pmt133 is right about epxoy and csm. Sorry, I forgot, but it isn't compatible with the adhesive used to glue the strands together. Gel can cover 36 grit fine, but it has to be sprayed really thick. It can be applied with a brush, but you just can't get the build up of spraying. What kind of...
