Retarding Zero clear coat drying time

Has anyone had any experience with retarding the drying time of Zero pre-mixed clearcoat? I find it's setting up way too fast and making it difficult to keep the finish as un-peeled as possible. It is really tough clear, which is what I like. However, it makes it difficult to knock down and polish in corners and in recesses. Do I just need to go to 2-part clearcoats?

Cheers guys

If you're using the 1 part clearcoat, you just need the correct thinner/reducer for it. Steve should sell it on his site. I would guess that it would be Lechler's lacquer thinner.
