Rob, Is the only reason that you would not use the Vinyl ester because of the fumes? I have tanks in 357cj made of both vinyl ester and saf-t-poxy (I think I recall) The wing tanks are the vinyl ester and never been a problem with any and all types of fuel. But the header tank that I got from Rand Robinson was made with saf-t-poxy that is supposed to be for fuel. The first time I had to use auto fuel with ethanol it eroded the epoxy of the interior of the tank to the point that there was a coating through the entire intake system. I only discovered it before an accident because the aerocarb slide was sticking. I had to cut open the header tank and re-coat the entire interior. (you could actually see where the fuel level had been while the ethanol fuel was in the tank) The intake system was dismantled and cleaned. The combustion chambers appeared to be OK as it probably burned the resin up. The fuel was only in the tank for about 5 days before being used up and replenished with av-gas. The fuel that did the damage was 5 gal of Sunoco 93 oct. which was the only thing that i could get at the end of the day on a Sunday on the way home from the Tennessee gathering. ?? ?I do not know if the west system would hold up to fuels although it has not harmed the skins of 357cj in any way that I am aware of. The header tank I am making now is being made from a solid block of foam shaped to the configuration that fits under the foreword deck. That is why I am not using the 1/4" last-o-foam as the shape is not conducive to flat sides. The flat sided type of construction is what I did use on the wing tanks of 357CJ. 14 years ago. Joe Horton

Two layers on the inside, one on the outside. I did not do the deck cloth on the inside, but I did squeegee in a batch of resin into the weeve after the two inside layers were dry. It seemed to work fine. Only issue I had was the bottom not sealing quite right. I did have to pour some epoxy into it later to seal the edges/corners. ? I would not use vinyl ester again. I'm sure the West System would do just fine. You never want to put fuel with ethanol in it, regardless of construction.

Since I bought the one that is in N357CJ I really did not think about how many layers of glass there might be in the construction. Right now I have 2 full layers of the 5 oz glass cut and one layer of the deck cloth on the interior of the layers. I am making it in a top and bottom half so I could always add layers inside or out before I close it up but I would like to be close in the first lay up. What are the opinions of the total layers of glass needed? BTW- now foam core just planning on glass/resin only.
