[R-390] FW: stripping paint

[rbethman]

I've only seen ONE knob that crumbled.  Out of hundreds I've either had 
or still have.

The only thing I have seen that is similar to the issues of Catalin, is 
acetate.  Not only is it extremely fragile, it will burn rapidly, and 
should never be stored in any significant amount together.

It is one of a number of long outdated things that were developed for 
what was intended to be "good" ideas.

The infamous Dynamite developed by Nobel was one of those intended 
"good" ideas.  That was until it was found to sweat when too warm. It 
sweated pure drops of nitroglycerin. Tended to make things very interesting.

This brought about the invention of TNT.  Highly stable, and "almost" 
foolproof.

YMMV.

C4 doesn't blow up while it is burning no matter what you due to it!  It 
is great for heating C-Rations.

It is far safer than the old blue foil wrapped heat tablets.  We saw at 
least one overzealous person during training that "tried" to remove it, 
only to find out that it was indeed burning with a colorless flame.  
Everyone saw the results and never tried that. Just let it burn out on 
its own.
