Hi,
I need to do a repair on an ABS garage door. I found some info on the
Net explaining that ABS plastic could be dissolved in cellulose
thinners to produce a paste for building up broken parts. Problem is
how can I tell if a potentially suitable plastic item for dissolving
is actually made of ABS. Is there some king of identifying test I can
do?

You would probably be better off looking for a repair kit for the ABS
door. Maybe the manufacturer could recommend one. Commercial ABS
materials are normally not pure polymer but contain a variety of
fillers and other chemicals, so in my opinion, it would be hit or miss.
