The Beast Grew a Tumor!

[Crocodile56]

Its really not funny, but it is kinda funny! But there it is, a funny looking tumor that grew on the tank in one day and stopped growing!

Anybody ever have a bubble form under the paint like this?

No gasoline leaking outta the tank.

Anyone know how to fix without stripping the fuggin tank, Blacksheep?

These are the best pictures I can get, damn dull paint job!

Well Croc, as I mentioned the other day, some times either the primer or the bare metal itself gets something on it, and nothing will stick to it. I had a fender on a Road King about 6 years ago that kept getting a spot on it like this. After 3 times of redos , and nothing seemed to work, I strippied it all the way down to metal and re primed using urethane primer , then base coat and clear. BAMM 4 days later it came back. We finally had to get a new fender and start over again. Now, it looks like maybe something got under it and contaminated it right before you started. It 's in kind of a hard place to just repair though. I hate to say it, but you may have to get down the metal and get whatever it is off of it before you go back with more paint. Let me know if I can help.

Oh crap! :(

Maybe a cut and a two part epoxy repair under it, then smoot it out with your finger. Let it eat for a month or so, then come back and shoot a few more coats of clear over it to sMOOOOth it out.

Dammit man.......I sanded that tank down to bare steel and ground all the welds outta her, its really two tanks put together and I removed the gas gauge socket and installed a fuel cap socket. I really took my time on this tank, after everything was ground down I put her in the blast cabinet and blasted her, then 3 coats of K2 primer sanded her back down to glass finish and shot her with one more coat of primer then wet sanded with 1000-2000. Then the base coat paint etc. it make sence what you say, something in the steel, but shouldn't I have seen that in the primer?

Wat ya thimk about super glue infection? Put some super glue in a syringe and put a little at a time under the bubble working the bubble to where the needle is inserted, thimk that might work or just eat the paint from the inside out?

I would have agree with Blacksheep, Croc. I have seen this happen many times painting cars when you take them all the way down to bare metal. Some imperfection is in the metal in that spot and it causes the paint to lift. Unfortunately the only way I know of to fix it is to take it back down to bare metal and start over. Damn shame that is a fine looking paint job.

Croc, your talented way beyond anything I can do but IMO why not try the superglue trick. What do you have to loose? If it doesn't work you're no worse off than you are now. This is your beast, correct (not a project for someone else)? Do what you feel is best for what you want. Hate to see all that work go down the drain but that may be the end results.

That might be worth a shot!!! If it doesn't work you haven't lost anything at this point.

Too bad you can't pop it with a needle...like a pimple! I know you have hours and hours on that tank! That fuggen sucks!!!

[Ironhead]

that sucks Croc. I'd try the superglue trick, worse case scenerio, it doesn't work and you are right where you are now

[Bonsai]

I don't know a damn thing about paint but I'm pretty familiar with glues and adhesives. Seems to me Super Glue will tack up quick and start sticking too soon and not give time to smooth it out. Plys it doesn't flow all that well when it starts to set and may leave lumps. A two part slow set epoxy, maybe marine type since they are used on clear-coat won't eat the paint and give plenty of time to work it out? West Marine makes some kick ass epoxy resins in several set times.

Found the Culprit!!!

Well tried the glue thing and that was a no fuggen go, so out can the razor and well just look at what caused the bubble.
If you look real careful at the last two pictures you can see three tiny little spots in the steel, that was dead center of the bubble! So I guess I better get a tank of oxygen and start welding a new skin on that spot!!!

[Boss]

That fuggen bites too! Right in the middle of both colors too!

Wow! Such small imperfections to cause such a bubble! That is enough to make you pull your hair out.
