Hi Mark,

A general rule of thumb that I use is the smell test. If it smells aromatic (like gasoline) then the possible thinning agents are:

o MEK
o Toluene
o Acetone
o Naptha

If it smells like an injection prep (like isopropyl alcohol) the the possible thinning agents are:

o isopropyl alcohol (91%)
o denatured grain alcohol (91%)

Everything else thins with water (for the most part).

Mixing up a small sample will quickly indicate whether its suitability as a thinning agent or not. Be sure to work in a well ventilated areas with appropriate breathing protection.

One of the more memorable was thinning GOOP! with toluene. The mixture is great for sealing nylon fabric later to be sewn into waterproof flotation devices and other such inflatables.
