Shark Attack

This is really neat.. The only concern I have is what long term effect is this going to have on the paint? can it possibly make it seperate from the surface? Make it crack? The damage may not show up till the cars runs through all 4 seasons

Eharrison

What are four seasons?

I've heard of this before. So, i figured hey ill try it and see for myself. It does remove part of the dent but not to the point where it isnt noticeable. Waste of time.......

Welding supply distributor with a name like Gas Pro that sells gas and has the big tanks. One of the gases besides argon, nitrogen and others is CO2 .
They probably supply to guys who ship groceries and such. Yellow pages might help. A refinery might be able to tell you. Maybe ask who they sell off gasses to thats a welding supply company. Be sure to tell them it's dry ice you are looking for because they might know exactly where to get the bricks. Grocery stores the deal is it comes in some boxes of stuff under styrofoam to keep produce cold. Might be best to ask a produce distributor while you are at it. At your local grocery store try asking the guy in charge of the greens receiving. If you are lucky some of the dry ice has survived and he can store it for you to buy.

Good question Kyle! I was thinking the same thing. Constant heat/cold/heat/cold can't be too good for the paint?

Eharrison

Only poking fun at ya! I was thinking last week when I was putting in the gearbox how you did it in the winter....I hated doing it as it was, let alone with a frozen floor....

Shark Attack

Especially EXSTREEM cold like dry ice and applied FAST.. what if the paint contracts faster than the metal? Its going to pull from the metal or its going to crack.

I know.... Just tossin in back!

RPMulli

I did it and it doesnt hurt the paint....

pissedpuppy

he invented that, I believe

How do you tell if the metal has reached the same temp as the dry ice?

An IR thermometer works well, or just wait till frost forms on the sheet metal.

and BTW, no paint damage whatsoever.

if popping dents out from an area once or twice you should be safe. If continually doing it can result in damage. I have a metal garage door at work that has liquid nitrogen spraying on it when filling. After a few years the paint has peeled off only in the spots where the liquid hits it. But then again liquid nitrogen is -320 f
