A story...Many years ago, I got a gas tank for a Norton which had a small dent...I had the bright idea of stoppering all holes, installing a Schrader valve [tire valve] in the gas filler plug, and putting about 3-5 psi compressed air in the tank...And then heating the dent with a torch to pop the dent out...Big mistake...No, no explosion (no gas fumes), but the superheated air billowed the sides of the tank outward like a set of waterwings...Ruined the tank... So that doesn't work...
PDRPaintless dent repair.
That dent cannot be removed with paintless methods...the crease line is the problem. Places that do tank restoration charge between $200-400 to open a tank, remove dents, close tank and resurface for primer coat. When you can find people who know what they are doing.
I've got a very good friend who does this for a living...and got it pretty dang close. After paint, perfect result.
I tried that with my Honda tank. ..Lesson learned. Don't pump air into a gas tank.
I've found references in other cycle forums for Dent Dynamics in Sonoma California. I'm thinking of them as a kind of last resort (or Rick Dale! ) I'm not too worried about the paint itself; I don't like this color anyway (I like the Garnet Brown color offered in 1971 by Honda).
That's a pretty small dent. If you're going to repaint, can't you just do some filler or some lead solder?
Understand the concept of a dent first. Yes, what you see is a low spot. But around that low spot is a ridge (high spot).
Try this trick first!!Take a hair dryer and heat the dent area so hot you can't hold your finger to it then put a piece of DRY ICE on the dent. The HEAT anneals(softens) the metal and the DRY ICE causes a RAPID shrinking . I've used this method to take hail dents out of Aircraft skins.Xnavylfr(CHUCK)
Sheesh...stop worrying about perfection...fill it and paint it. See my B4 and after pics. A lot of damage was under my paint job when I had it blasted. Never knew. Re-bogged it and repainted it. Looked just right ....or I could have gotten an expert to deal to and spent another $600.
