Hi Todd, I have used something like you describe below to coat the inside of a metal (steel) motorcycle tank that had rusted years ago. The kit came with an acid for cleaning and etching the inside of the tank for adhesion. The stuff I had was a two part I think, white in color and looked like white liquid ceramic. As directed, once the tank was as clean as I could get it and etched with the acid, I poured the liquid in and and rotated the tank around and around to make sure all of the inside was coated. Once set up the inside was kind of shiny like glass. I could stick my finger in the fill opening and feel of it and it felt smooth as glass. It worked very well. I am not sure I would have faith in using that product in a resin based fuel tank. I will admit that I have no idea whether it would stick properly but I would guess it wouldn't work that well but I was wrong once! LOL
AS for PRC, I think that is the same stuff I coated the inside seams of my Mooneys fuel tank with. Jeff can probably speak to this, but that was one night mare job cleaning all of the old stuff out of the whole tank through the too small openings and then cleaning and cleaning and cleaning and, well you get the picture. Bottom line is all oil residue has to be gone or the new sealer may not stick properly. I see that as one of the main objectives of coating a used tank that has had oil in it. Larry Howell ________________________________ Hi Folks, I have noticed the recurring discusion about tank sealers, and their susceptability to problems when using MOGAS with Ethanol. I have had some experiences in the past with metal Motorcycle fuel tanks which rusted through due to poor maintenance, namely allowing water from condensation to sit on the botttom of the tank (for years appearantly.) While large leaks required welding to fix the problem, if caught early they are often fixed by coating the inside of the tank with an aftermarket product called KREEM TANK SEALER. It's available at many Motorcycle Parts Suppliers, and even JC Whitney, in various sizes for between $20 for a 16 oz kit and less then $60 for a gallon kit. I have a number of classic and antique motorcycles, and after treatment with this product have not had any of them develope new leaks after years of use. I usually use the cheapest gas I can find, and often it is part Ethanol, and seems to have no effect on the sealer. As a product that is specifically designed as a fuel tank sealer, it might be worth it to you guys looking for something that will stand up to Ethanol to research it.
