If you apply dry monokote using their "Trim Solvent" you should never have any problem with the trim lifting. Acetone, lacquer thinner, or MEK may work to some degree, but nowhere as well as Monokote's product. The active solvent in their "Trim Solvent", and what gives it it's characteristic odor, is - cyclohexanone. I have used cyclohexanone for years to "glue down" my trim and have had zero lifting.

I used to use it in a business I had and bought it in 5-gal cans for about $45-50. I still have a few gallons left and all I use it for now days is to glue down my monokote trim, so it's probably a several lifetime supply. It may be hard to find, but look under industrial solvents in your yellow pages. My guess is that it probably is in the $20-25/gal range and you might not be able to get a smaller supply. Find a few friends, buy a gallon and split it 4-8 ways and you'll each have a pint to a quart for less than you would pay for 4 oz. of Trim Solvent, AND you can stretch it further with adding another ketone. Very little goes a long way.
