Bought my first boat to cut, gut and rebuild from bow to stern, including engine. Killed my back and suffered the wrath of the fiberglass demons

17x12ft is very large. Who measures the resin in weight. isn't that in gallons?

Yeah it is large.... like I said...I gave him larger numbers than what I probably need su I know what I'm possibly looking at for a ball park price

Cross reference pricing with online US Composites
12' wide is way ridiculous. Just lap it.

Today was a productive day. Didn't get done exactly what I wanted to do but productive nonetheless. Got some more supplies including 25%of what I need for glassing. The guy was great! Answered all my questions and even threw in stir sticks..... chip brushes.... mini paint rollers... roller heads and even a fiberglass roller! He even took about 50.00 off the price and called it an even 300.00! Got an electric scissors from harbor freight as well as another angle grinder. Mine made it through all my grinding but finally sparked.... smoked and took a crap today. Got my csm and 1708 hung up in the tent.... got a pop up tent for extra work space in the rain....I created transom templates. I realized that the transom isn't 1½inch wide like I suspected. It's only an inch wide. I'll probably do something to that to make it wider. There's also a small triangular section at the bottom of the transom that is wider then the rest of it. I had to create a 3rd template for that and I'll just have to grind the plywood down about ⅛ inch. I grabbed my fuel tank and got the old hoses off of it. Found some fiberglass powder inside the inlet..... found this odd because I removed it from the tent long before I started grinding. I stuck the shop vac inside but I don't know if I got it all. Hopefully so. I busted out my wire brush attachment for the grinder and started cleaning up the tank.... boy did she ever get shiny! I'm looking for pin holes. So far so good! I'll probably cover the tank in a layer of resin just to give it an added layer of protection. Next up..... stringer templates.... wood cutting and glassing!

I also see that I'm goimgto have some decent sized gaps at the bottom of the transom will that be an issue?

I would also like to give a big shout out to JASinIL2006!! He had a spare tub of cabosil sitting and ended up shopping it to me!!! Thanks man! Your the best!

Cleaned up the gas tank today.... she looks brand new! Did a 3lb pressure test... all good there! I played with the resin catalyst and cabosil mix and slapped a layer of resin on half of the tank. Will get the other half later. Will check to see if the reason hardened when I get home.

why are you putting resin on the tank?
the cleanup may not have been needed. aluminum like copper form a protective patina.. I will come back anyways

 

[kcassells]

I've read about that before but never understood the reasoning of coating it. My tank went raw and did the patina. Never set in foam and set on the recommended rubber pads to prevent another corrosion.

How to Install an Aluminum Fuel Tank on Boat or Yacht - by David Pascoe

Many people blame aluminum as being a bad material for fuel tanks. Actually, it's not. All materials have their strengths and weaknesses, and the problems with aluminum tanks are problems of proper installation, not the material itself. Properly installed, aluminum tanks will usually outlast the...

It was a recommendation from someone here a while back. I also wanted to give it added protection. I know clean up wasn't necessary, but she's been treated horribly.....Just felt fitting to clean the tank up.

It was a recommendation on here a while back, and the way it was explained made sense, so I did it.....but for the life of me, I can't find the post.

probably not the best idea to coat the tank in resin or for that matter powder coat as some do .
best is to get some epoxy paint and a good splash over.

any chips in the resin that get salt water in start to corrode and can ruin a perfectly good tank over time , just paint it or leave it raw.

I'm in Wisconsin. No salt water for me

leave it raw , fresh water wont even need to be coated .

I cut one piece of plywood today and laid down my first Layer of glass! Took 2 cups of resin. I put down a piece of csm on it..... but I do have a question now..... there's little csm fuzzies on the edges and resin for under and hardened on the other side and it's not nice and flush anymore.... how do I get rid of the fuzzies or keep them from happening again and what can I do about the clumped up resin?

I also got neoprene strips and 5200 and Laid out steps under the fuel tank.

I also took a gamble and purchased that powerhead I found on ebay..... don't judge me. This is how i learn... got the old powerhead off and cleaned up everything with the power washer. I even got lucky and fond a new fake on Amazon that fits perfectly!

Tomorrow ill work more on the transom and getting the powerhead installed.

Oops. Forgot to add pics

Did you use the roller on the csm? If you roll it out when things are wet it won’t clump. you can sand/ grind the clumps flush. Learning curve.
the extra fuzzies happen. Cut them with the multi tool. It happens.

 

[todhunter]

Agree with above - cut the overhang with a multi-tool then sand the remainder back

 

[aspeck]

More sanding!

Rewet the edges and any exposed voids
