We have either used or are currently using the products you see below, so we feel confident in recommending them to our INZANE SKINS customers.
If you want top clear coat over top of a skin, you'll need more than both 1 or 2 cans so we recommend the 3-pack of Spraymax. If you're planning on clear coating over many guitars, grab the 6-pack OR consider getting a spray gun and using the Transtar 2K urethane with activator in the big containers. They offer more value than the spray cans.
