Well, Since I got the IMS tank, I was immediately unsatisfied with the less than perfect welds, molding, imperfections, etc. I liked the idea of the extra fuel and the protection it provided for the the radiator but it was UGLY!
All the info was, "Nope, can't paint an IMS tank, paint won't stick, stickers won't even stick." Wasn't sure why so I did some research. Most plastic tanks "breathe" hydrocarbons that don't allow for painting and such. OK, how about sealing the tank. Lots of sealers out there but they all say won't work with Polyethylene, Hmm. What is the IMS tank made of anyway? Yep. Polyethylene. XLPE, to be exact, cross linked polyethylene. Caswell has a nice looking 2 part epoxy sealer, oops. Won't stick to Polyethylene.
I finally came across a sealer that the manufacturer wasn't sue if it would work or not but thought it would. I found some blogs that some guys had used it and it worked great but I didn't know if their tanks were XLPE.
Long story short (too late) I ordered some and after a lengthy prep process I sloshed it around and let it cure. Seems to have dried to a flexible, strong bond, time will tell.
IMS tank is not ugly anymore! I have a bit of wet sanding the clear and some polishing to do but that is going to wait a month or so to see if she holds up...[IMG][IMG]
