I use it to clean up covering irons and to go over a newly covered model to seal the edges and clean up any color that bleeds thru.
Trim Solvent is expensive.
The best way to apply it is to keep some in a old CA Accelerator spray bottle. That way you can easily control the amount that you need. This works way good.
Mark the outside of the bottle so you'll know which is which. Don't ask how I learned this! (Trim Solvent doesn't do much to kick off a CA glue joint.)
