Hello, I'm working on Halcyon's Attacking Alien Warrior and there's quite a few seams to fill. I've got the head sanded, puttied and glued, so here's my question:
When sanding the plastic and after I've glued the two halves together, I brushed on a coat of Testors flat black acrylic to see if the seams are smooth enough. They are, but you can tell where I've sanded if you look close enough. I used very fine grit sandpaper so the scratches aren't real big, but I've wondered if you can polish it up somehow so it's really smoth? Should I put a clear coat over it to smooth it out? Thanks.

There are several products out there for such a thing. Mr. Surfacer for one would do exactly what you are asking, but then again it's rather costly.

Another question I have back to you is the sandpaper you were using, can you use it "wet". If you don't have a very fine grade of sandpaper, I would suggestion you sink a little money into that. Sanding wet has a few advantages over normal dry sanding, for one you get an almost glass-like finish (with the right grade sandpaper). When I mean fine grade I'm talking 1000, 2500 and 4000.

Hope that helped!

Hmm, lets see. The sandpaper I'm using is 3M, I don't see a number but it does say wet/dry. I think the grit is prett high, probably at least 1000. I'll go check and see what the flat coat did... Whoa. Dude, it's great!!! The head is almost perfect!!
How do you wetsand? (I think I can guess, but just to be sure... )
Also, on the front of the head there's these little ridges that I got a little putty into. What would be a good too to use and clear that putty away? Thanks

You can try using a toothpick to remove the extra putty out of those ridges. The toothpick shouldn't hurt the plastic. The wet sanding, dip the sandpaper into a bowl of water and put some on the plastic. At least that's how I do it.

Thanks. I'll try the wet sanding on the main body as there's lots to clean up... and I do mean a lot. I'm on 'putty and sand' round # 4.
