The ratios are usually 25% to 30% B-72 in 75% to 70% acetone. Acetone
rather than toluene because it is a friendlier solvent to you and the
environment. I will warn you that it takes days for all the pellets to
dissolve so don't expect to use it immediately. Also, the bottles need to
be fairly airtight; divide the batch up into small bottles. The acetone
evaporates fast enough to make the last bit in the bottle very thick and
bubbly (have to add more acetone to get the right consistency.)
The premix from Light Impressions is really easier to use unless you are
labeling a large collection in a short time.
