Using body filler.

It's called Newtech. Just checked.

Too bloody expensive to just fill dents. Newtech is for filling holes.

[Pussy]

Just figured I should ask someone who would know before wasting all the filler! I'll have to wait untill tomorrow, anyway. Nah I took the bog off, it's bare metal all over, now. Might as well try it out and see if I can do it in one go, then...

Get hold of Frenchy on kb.
He's a gun at this sort of thing

I'm pretty sure it's what panel-beaters use. I got it from Repco.

my experience working with a panelbeater for 3 months over summer is that panelbeaters use good ol' bog and slide hammers (and weld up anything structural), but for tanks you either knock it out with a rod+hammer from the inside then bog the finish, or buy an extra big pot of bog

Newtech is for filling holes.

+1 I've used a pot of the carbon fibre stuff to hold together cracked fairings in lieu of a plastic weld and it worked well, but the finish was no too great due to the fibres - good thing it was inside the fairings.

put pressurised air in the other and heat the dent gently with a blowtorch untill the dent pushes out. That's the only way I could think of doing the dent without proper tools.

NOOOOOOOOOOOOOOOOOOOOOOOOOOOo!

assuming you fill the tank with water or something to prevent fire, and dont blow the tank apart at the seam with the explosion (from steam or fuel), that is just as likely to pop out the factory leg groove dents as anything else.

my experience is lots of bog and lots of patience wins the day. It comes out well and as said earlier be sure to have a good key and don't let greasy fingers in there.

Experiment (ie, cockup) tells me that if you lay it on far too thick it gets quite hot as it sets. the tank expands, bog peels off. do it in thin layers, and yes a cardboard profile helps, even if it's a guess cause there's no other crotch end of the tank to copy

oh, and get one of those soft foam sanding blocks if you haven't already

use metal-tech it like 2 bucka from super cheep i filled some dents in a tank not to long ago and it came out mint just take ya time make sure you go down to bare metal ruf it up give it a good bace to build on then just small layers at a time and build it up, im not a expert this is just what ive always done think thers a pic in my profile of finshed tank


good luck and enjoy

There are some dickheads around here.

Get some Nutech, I think that's what it's called. It's a 2 part filler with aluminium fibres. Been using it the past couple of days and it's the shit. It'll stick to anything, you can put it on as thick as you like, it's changes consistancy as it dries so you start out with a rough shape and as it hardens you fine tune it until it's like working with clay, and it's easy to sand. I'm pretty sure it's what panel-beaters use. I got it from Repco.

We have used that before, it's not too bad at all. Beter than stupid fiber glass filler

I would but I can't bang it out myself and I'd rather use this old tin of body filler that's getting no use, than pay for someone with the tools to do it. I mean, even if I did push it out, wouldn't you still need to use a bit of filler to cover the creases?

Yeah you still want it smooth don't you?
Many bog jobs will get air bubbles in them, just mix a little more and go over it till they are filled and sand her back
I did this job on my cage yesterday, just normal CRC bog

Well of course I wasn't going to try it right now, but I figure there has to be some way of completely purging a steel fuel tank? I've tried pushing it out with a few spanners and anything else I can fit in and get to the dents with but I don't think it's going to work!

Slide hammer......

[Ixion]

How to attach it ?

How to attach it ?

Grow some balls, a Mig and some decent steel pole, make a shape like a U bolt, weld it, get your slide hammer, whacky smacky and you are done. Just keep the tank sealed and full, it's the vapor that burns.

And a lovely weldy lump on my nice tank!

If I wanted that sort of shit I could drill a little hole to attach the slidehammer with.

dude, fill with water (or any other cheap, nonflammable substance) and leave it open. heating a sealed container is never wise.

the water won't be in there long enough to cause rust.

and then have to weld the hole back up.....

either way you're using bog

Then you have to weld the side of the tank up after you do your hole ends up just the same, that's how we do it anyway

I have seen tanks left for weeks full with soapy water welded and explode. But I know of people who keep the tank full of gas [to the top] so there are no vapors and they still have their faces

Precisely the problem. I want a way to boof the dent without having to weld things to the tank (especially if it's a chrome plated tank !)

There must be a better way.
