Well we shot the DTM (2 coats)

we have started the process of sanding down the urethane primer
http://i1078.photobucket.com/albums/w497/slawnski/1964%20chevy%20c-10%20Montana/4bee47a9.jpgto smooth it out - we now have some fine scratches that we would like to take out- can I use a polyester high buid (easier to sand out) primer? We plan on painting the truck with single stage urethane- any suggestions? I was thinking glazing putty but the scratches- though very small - are all over- I don't want to sand out any more for fear of hitting the epoxy and or sanding down to bare metal.
