When I worked in a margarine plant we used a frozen carbon dioxide system;
a high pressure pump blasted the equipment to be cleaned. All the 35 years
of paint came off without affecting the metal parts of the machines. It
would, however, destroy any plastic parts or other materials such as
insulation.

Hello,
When I bought my Tiger in 1976, I didn't realize how rusty it was under
that brand new coat of paint.
in 1979, the rocker bubbled and I tapped the area with my finger. Right
through...
So, all around the car fresh metal. Cost nearly as much as the car.
Another
complete paint job and rust removal after being hit in the rear in 2000
The trunk floor had been painted (when I bought the car) with a tarry
substance to cover the surface rust there. Over the years, I've thought
about
haw to tackle the trunk and bring it up to the standard of the rest of the
car. Recently, I committed to an attack. In the last month I tried
chemicals
(paint thinner, lacquer thinner, then acetone) and just made a mess. Then
tried a stiff putty knife in a cold garage and got down to rust and
original paint. But, this approach would take forever and leave the
paint, rust
and traces of the tarry stuff. I thought about media blasting but the
resultant "stuff'" would be there for ages. And get painted in.
This weekend I stumbled on a new (to me) system of blasting: Dry Ice
blasting. This would make the now dried-out tarry stuff very brittle and
take
the trunk area down nicely. And no residual media (Black Beauty, glass
beads,
and the like) to worry about.
Anybody done this? Any comments?
