Trim solvent is a wonderful product to activate the glue when joining colors together as well as being good to remove color stains from iron, covering ect.
One thing though, if youve never covered before, Id recommend keeping it simple and use the experience to take it to another level next time. Covering is not hard, nor is it simple to get perfect, if you go too far the 1st time, you may burn yourself out.
Another tip, Monocote Trim Solvent is very expensive. I have started using acetone, the active ingredient in the product, available at any hardware store for pennies on the $.
