I would stick to ordering marine supplies. If you are going to do it you might as well do it right.
When you buy a marine product to put on your boat you may not be getting what you expect. Certain marine epoxies do have the strength to deal with the constant pounding of waves. And if you sail off a beach being dragged up the beach but I have most simply do not. I find that there is a large difference between marine and " home depot" resin, and I am strongly on the home depot resins side.
I have found that resin is stronger and stiffer than epoxy which is what is required in this application. When it comes to the brand of resin I have found there to be little difference in the resins except their name. The only thing you really need to look at what the label says about water resistance. If the label states waterRESISTANT Do not buy that resin. You want a resin that says waterproof. I personally use a cheap resin from home depot.

Are you talking about epoxy as in a glue instead of epoxy resin?

I've messed with epoxy resin and polyester resin with repairs and found the epoxy resin to be noticeably stiffer. I also chose an epoxy resin which is supposed to have a better mechanical bond than polyester...which on patches, a mechanical bond is all you are able to rely on. That's just my experience though.

Sometimes that's true, sometimes it's not.

The label "Marine" or "Marine Grade" can be a come-on, it can also denote stronger than household, more UV resistant, more workable for the types of jobs boating requires. Like nearly everything in our lives, it's up to you to do your homework and separate the hype from the reality.

In the case of resins, manufacturers publish and post data showing key properties such as viscosity, tensile strength, and adhesion. The same company can make both a household variety and a marine variety. Their product description may only say each is good for its intended purpose. You can take their word for it or you can look for yourself to see what the real difference is.

Some examples of the information available to base choices on:
oh and another note of something I ran into. Everyone has their way they like to do things and thier opionion of the best way. Myself included and nothing wrong with that at all, best thing is to research and culminate all the different ways mix them up and use them however u think they will work for your situation and how you work.

OOOkayyy...guess newbie soon found out that fiberglass can be a pretty sensitive issue around here...hahaha. No, really people. Your posts are helping a lot. They are leading me to a lot of helpful places I had no idea existed.Please keep them coming.

So, this is where I am in so far: The hull is still driying out resting on it's newly constructed pair of saw horses. An aditional inspection port will be cut either tomorrow or Monday after I come back from camping:cool: all pending on the shape of the camper when I re-open it tomorrow (this for better drying and acces to the bow area for repairs), gather all this info (along with some courage) to root out the bad fiberglass next weekend, then, whenever I finish cleaning the wounds, start patching things out. Will keep you posted, and if there are any objections... I say suggestions to tis plan, please do make yourself be heard.
Happy sailing to y'all this weekend (guess it is canoing for me)
