ummm, i guess you could try, i'd just be concerned about compatability between the 2 paints, the rustoleum/tremclad is a acklyd based enamel, and that clear is for acrylic enamel, which is typically a single stage process paint. i'd stay away from anything that uses a hardner, things could get ugly!!!! i would just try to cut/buff the paint straight, unless your lucky enough to be in canada and can get the tremclad.
I found that rustoleum does have a clear coat available in non spray, in their industrial line (about $50 a gallon).. but it's not available in CA. Damn. I think I'll have to give the spray a shot since that's the only game in town.. as long as I can wetsand any imperfections out of the spray and it still be glossy, i'll be happy..
