The thinnres is one of teh best ways to destroy ploystyrene known to man
or alien. If ou careve foam to shape and mould galss resin or pa;[ier
mache around it, you can get teh styrene out afterwds by wshing it with
the thiners.

Its also a good paint brush cleaner.

melted the handle.

Its a bit expensive as brush cleanet IMHO
