I have been working on bikes for 40 years, and thought i would save some of you a lot of time.Removing rust with vinegar, coke, muriatic acid, or whatever, will not cure a rusty tank-in time it will only come back stronger.I have used Kreem and por15, but there is something better-Caswell-you dont have to remove rust , just clean it good, the Caswell will stick to the rust. Just My 2 cents---
We use Red Kote for our fuel tanks, works awesome: http://damonq.com/Red-Kote.htm _________________ Honda CB450D

Curious-- do you let it drain out of the petcock hole or hang it upside down so excess drips out the filler hole? I read the directions & the say it should NOT be allowed to puddle.

Thanks.
Here is some other application(Caswell product) versions including draining. Check crossover vent if applicable and keep blowing out from time to time.

After reading quite a few reviews online I decided to try the Caswell epoxy liner product.
The paint on my gas tank was in pretty good condition and I didn't want to ruin it and have to repaint.
Most other products use chemicals that would affect the paint, and I was quite sure that I would spill something on the paint.
Prep was straight forward and easy, I cleaned the tank with drywall screws and rinsed with acetone. (and I did spill some acetone on the paint but it evaporated before doing any damage!) I used a vacuum cleaner outflow to dry the tank between cleaning steps.
I removed the fuel petcock and put grease on the threads of the mounting bolts (to ease removal and eliminate plugging the threads) and reinstalled just the bolts, then I taped over any remaining holes. I wrapped the tank with plastic wrap which was a good move as once you get the epoxy on your hands it ends up in places you dont want it.
After mixing the two part epoxy for two minutes, I dumped it in the filler neck, covered the hole with plastic wrap and installed the gas cap.
I proceeded to rotate the tank in every direction for about 45 minutes (this stuff has a super long cure time) and then took off the cap and drained the tank upside down. After a few hours I removed the tape from the holes and trimed the hardend epoxy (still somewhat pliable) with a craft knife and removed the greased bolts. (this worked perfect)
The finished result looks like the tank is lined with glass and it appears that it bonded well.
Time will tell.

I have used kreem because it was the only thing that we had at the time. Then switched to POR when because it was better then Kreem. Personally, I have checked out the caswell stuff and it is a very excellent product. If done right we shouldn't have any of the problems about it getting destroyed by the chemical additives they put in the gas these days.

my question is: how would this work on a tank with a built in pickup? ive read somewhere that the tank on a VFR has a screen and pickup tube that does NOT like POR or kreem, and it should NOT be done under ANY circumstances. _________________ No, actually I DONT sleep much, I have M.A.D.D (motorcycle attention deficit disorder, means i change bikes about twice a year) drink too much coffee, have too much energy and dont do much besides work and motorcycles.

The caps are vented - it's possible to plug that vent with sealer, it will cause all sorts of craziness when you finally get it running.
Better to use a great big ol' cork or stopper to plug the gas cap hole............ _________________ Bill Lane - CB200-CM200-CB450-C70M
