well i have been searching all day and i have found a solution to the tank decal problem but it isnt what i originally wanted to do. i cannot find any kind of tank sealer that i trust to not come off and get into the fuel. the only solution i see is that you can buy sheets of tyvek that is similar to vinyl that comes with an adhesive backing. aparently someone got some of this and put it on his tank and after 3 months it is fine. im sure you could buy some of this tyvek sheeting and bring it to any sign or printing company and have them copy the design of your original tank decal onto the tyvek and print it out for just a few bucks. hope this helps Man, there's got to be something. I'm also very interested in sealing in the vapors that get through the plastic...not really because of peeling stickers, but more just for the environmental peace of mind. The stock tank does that just fine, but it's kinda funny looking and small, so I'm looking for a way to have cake and eat it too I guess. I know that the Honda Insight Hybrid car uses a plastic tank for weight savings with a layer of Ethyl Vinyl Alcohol to seal the tank, so it is very possible: http://www.insightcentral.net/encyclopedia/enfueltank.html I need to get my hands on some of that, or something like that that would do the same thing. Any ideas?
