DO NOT use poly with wood! It will rot in no time and this is too much work and money already to just have it rot out short term on you! You have two choices...I am planning to run 1 3” pvc pipe from the console back. The gas tank is in the stern, do you think I need more than the 3”? I have a 1” running forward for anything I need up there.
That’s the first I heard about not using poly resin, I already bought a 5 gallon bucket......
I’ll hook ya up! The core I refered to is basically unbranded divinycell h80. The blown pvc I use for transoms amd areas that require good screw retention is only around $150 for a 3/4” sheet. Hoping to make a trip and place a bulk order, anyone want in let me know. I’m sure I can get a case the foam core for around $95 sheet!3" pipe is huge and heavy. I went with 2" for controls, and 1.5 thin wall for wiring and transducer.
I agree with BB, either switch to composite or go with epoxy on the wood. Or you can just to it like you planned, but know it might only last a few years.
If BB can get you composite sheets for that cheap I'd jump on it. I might have to knock on his door soon.
