clear coat - acrylic or enamel

It doesn't matter.  I have used like combinations i.e. enamel clear over enamel paint as well as Future over acrylic which naturally work.  My more typical usage is enamel paints and acrylic Future over that.  The one posibility that I have not tried is enamel clear over acrylic paint, but I would expect that would work fine.  As long as the paint underneath is decently cured, you should have no problems.

that is what i figured but was not sure. thanks.
