Very cool! pun intended.

Where were you able to purchase the dry ice and how much was it?

I checked online here locally since is best to use very fast after pick up. I took 30kg which was enough when I put it in bags so I was able to move it around the floor. 1 kg was 3€ here ... quite expensive but it helped me a lot.

Hope you don't mind if I add to your post.  I did this over the weekend to a 69 02 that has been sitting in my garage for way too long.  I have been wanting to use the dry ice method for quite some time.  Since I have read about it over the years but never really had a need.  The 69 had the need.  There was no way that I was going to use heat on the amount of material that needed to be removed.  Do not spare on the dry ice.  I would say buy no less than 50 pounds to do all six pieces on the floor.  That would be the front two footwells, the back seat two footwells and under the rear seat there are two pieces.  I would recommend only using pellets if you can get them.  I used a 32 oz ball peen hammer.  Don't be bashful.  If there are holes in the floor they have been there and you will need to fix them anyways.  The longer the ice sits the better.  Minimum is an hour.  I think that I spent like $1/pound for the ice.  Well worth it.   Here's a before and after of the 69 that I am messing with.
