I was going to direct this to stormtrooperguy, but I figure I should try and catch as much attention as possible to get the most help possible.
OK, so here's the situation.
I'm doing a scratch build of Captain Rex ( might do a regular trooper, don't like the paultron tooo much), I have minimal tools and minimal money.
So far I've sculpted a head about my size out of insulation foam, covered it partially with bondo, found it hard to use, so I went to clay. The bucket is 80% done(in that it isn't a head anymore), it's just lumpy and off all over the place. I also bought plaster bandages to do the rest of the armor's base so I can build off of that, with clay? I don't know yet.
My only problem with bondo is that, I have no garage so I have to do bondo work outside, and, if it's raining, it's hard to do. My power sander isn't the best thing in the world either, so.. Clay is preferable. Right now it's cracking up a storm, but I can fix that, that isn't the problem. I just can't get smooth, round, near perfect surfaces. OH, also, it's air dry, no firing needed.
I realize I can sand the dome parts and stuff to smooth it out and level the edges.
Does anyone have any suggestions?
