Would this be good to 5200 to the bottom of the tank. I would cut square to fit the proper areas. Are there other better or cheaper options?https://www.mcmaster.com/neoprene-r...inforced-multipurpose-neoprene-rubber-sheets/
Aluminum tank install

Tanks should not be mounted on rubber.

I suppose that you could use neoprene but it has to be 'insulated' from contact with the aluminum. A continuous layer of 5200 should do.

Boats & Yachts: How to Install an Aluminum Fuel Tank
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...

Well, got my tank out today. I only had to trim a tiny bit off the lip stern to bow. It angled right out. Tank is ordered from alloy metal works on long Island. Will take about 2-3 weeks unfortunately. In the mean time ill spruce up the rest of her and go through some engine maintenance. If im feeling energetic I may attempt to recore one of the hold covers. Also need to run new hoses.

Neoprene is a good material to use. No carbon in neoprene. I would make sure their were no voids or crevices between neoprene/5200 and tank. The idea is to make sure tank is off deck to allow air to circulate and assure aluminum is not ever sitting in water.
Suggestions to rebuild floor hatch over gas tank 24 offshore
I am in the process of rebuilding my floor hatch. It is approximately 5 ft by 2 ft. Not sure what the best core material would be. Was thinking 3/8 or 1/2 in ply covered with ounce n a half mat? Biaxal? Woven riven? I know enough about fiberglassing to get myself in trouble. Lol.

We have a tank builder/installer in the area that has been doing it for decades. This is how he makes mounting pads to replace the neoprene crap that kills the tank.
Step 1
-RTV silcone - make large worms cutting the tip really short. These usually go in the 4 corners on the mounting surface, but each vessel will be unique.
-Let dry completely
Step 2
-Cover the silicone with 5200/4200. You can let it dry and rely on a mechanical fasting/wedge system or set on the wet adhesive thats covering the silicone.
This doesn't involve carbon so the tank isn't picking up a stray charge. Most important - "A dry tank is a happy tank"
