Acetone

Acetone is the strongest and fastest evaporating solvent around. Excellent for dissolving two-part epoxies before set up, for cleaning fiberglass repair tools and for thinning fiberglass resin (as fig). It can be said that it the Solvent for polyester and epoxy resins. Acetone will easily remove sticky residue on glass and porcelain left by stickers and labels, and will clean lacquer tools well. As acetone is highly volatile, it will work as a thinner for most oil paints and coatings as a drying agent but not in all. But it is highly flammable. Mixing with water dilutes strength and slows evaporation rate. Acetone is used in auto-body shops and boatyards, for auto-body repair, fiberglass hull repair and other epoxy or fiberglass projects.

Soak the brush in Acetone in between applications to keep the bristles soft. Just shake off acetone before each application. Acetone can also be used to clean resin off of things like scissors. These went in the trash because Acetone melts plastics. Acetone can dissolve many plastics, including those used in Nalgene bottles made of polystyrene, polycarbonate and some types of polypropylene. It is too strong for use as a coating solvent. It will attack plastics, synthetic fabrics etc and also it is non-photochemically reactive.
