Topic: Hot glue dent pulling.

[Don R]

 I pulled some dents using toilet mount bolts. I hot glued them to the tank, hold them tight to the dent until the glue sets. Cool with compressed air and walk away for a while so the glue can cool and set up. Then put a roll of tape, wood or whatever you have that looks correct around the dent and a piece of wood, angle or whatever you have that looks like it will work across the top.  Tighten the bolts until the glue gives up or the dent moves. Repeat as needed. It may pull paint so use discretion. Clean with paper towels and a hot air gun.
Pictures to come.  Happy thanksgiving,

I was able to pull a bad knee dent out of a tank using an inexpensive dent pulling kit from Autozone. It uses the same idea: hot glue bolts to the tank, put a plastic bridge across the bolts, tighten the nut, repeat. It worked very well for me, although I do have to repaint the tank. Here's a few shots.

I may just have to give that a try on a couple of bikes. Thanks for the post.
Normally, I use dry ice.

I'm going to get a kit! looks like more surface area than my toilet bolts. I almost tried alcohol, I should have done it.

I want to try it on an aluminum tank , the make the pull pins as small as 8 or 10 mm.
 Really dont want to weld to an alum tank if i can avoid it.

Dry ice works wonders.

please tell about the dry ice. My ally tank has some dents I wouldn't mind fixing.

I used the "pops a dent" like you have, tried pulling a dent on my 750 tank, wouldn't work. These tanks are much thinker than the dents they pop out on the TV commercial. The new cars have much thinner material. I ended up drilling a hole and using the tool as a puller putting a hook rod in the gas tank. It was successful on another dent with a little help from pushing it from inside the tank. I brazed the hole up afterwards.

 I ran out of glue and when I changed it stopped working.

I tried dry ice on my aluminum tank, and it had no effect. I was able to work out one of the dents out with a fabricated "bullseye pick", inserted through the filler opening, but couldn't reach the second, deeper dent. I tried a "Dent King" hot glue puller today with a couple of different "pin" configurations, and had no joy; the glue didn't stick well to the aluminum.

After reading the comments, I thought I'd throw this out.....there are different glue formulations.  The craft store hot glue sticks (clear to milky) are about one half the 'stickiness' of the ones used in industry to close up heavy duty cartons etc.  Those are generally, but not always, amber, have a higher melt point and are found either on line or at a local industrial supply.  All in all, a good hack for those dents.
