I have no major holes but tank leaks and has pin holes it is from 1985. Can i paint with gulvit and get about 5 years. I have looked at aftermarket tanks and there are none that fit exactly. I can downsize to an 18 gal from my 24 but the 1 1/2 filler are straight out of the top of the tank(I need the filler to have a 90 elbow. http://marine-fueltank.com/tank178.htm has an 18 but the filler needs to be rotated 90 degrees and is welded and I am loosing 6 gal of gas on a 90hp Merc inline six which drinks alot of gas in the salt water. Does anyone agree with gulvit, jb weld, epoxy resin and cloth. I need to cover my deck soon and dont want an above deck tank (no room).

NO>

Quote from the Gluvit FAQ page on the Marine Tex web site

"Can I use Gluvit to coat the inside of my gas tank?

No, Gluvit is not resistant to gasoline.

Gluvit can be used to protect the outside of an aluminum gas tank. Gluvit is an excellent barrier coat system that encapsulates the metal to protect against corrosion and pitting."

I have sent many a leaky gas tank to my local radiator shop to be boiled out, seams/pinholes re-brazed and epoxy coated inside. Usually runs about $100 bucks. I've never had a problem with one after.
