Removal</DIV>
<DIV><BR></DIV><BR><FONT face=sans-serif size=2>On cured epoxy solvent will
not work....before it damages your covering. Most likely you are using an
epoxy that you bought at a hobby store or similar. At about 130F it will be
above its glass transistion temperature, which means it will become rubbery
and lose much of its adhesive characteristics. Take a covering iron, heat the
epoxy directly with the iron and while it is hot you should be able to remove
the epoxy much easier with your razor blade. Epoxy is a "thermoset"
reaction so contrary to most peoples opinion, it will never melt nor
dissolve with heat or solvent.</FONT> <BR><FONT face=sans-serif

epoxy from covering without <BR>damaging it besides trying to pick it of with
a single edge blade or #11 <BR>blade. It doesn't stick to covering like it
does in wood but the blade <BR>leaves scratch marks on the covering. Any
ideas, anybody???<BR><BR>Thanks,<BR><BR>Ken
