I was hoping that wasn't the case, oh well. Thank you for your reply and insight EVApodman, I appreciate it.

Re: Polishing cream

There is some rough areas on the plastic one side. The clear plastic has also yellowed. I've been coating it with a 6% peroxide cream and keeping it in the sun. It has reduced the yellow. I also used some Sensodyne toothpaste to help smooth it out... I think it helped. Still needs some TLC though.

Polishing cream

Hi Guys, can anyone recommend a polishing cream for clear plastic. I know that Future is used for the final application, but I have a little more work to do before I get there. I did a search in the forums and this was all I can find.... --------------------------------------------------------------...

That hasn't occurred to me, would something like a rigid mesh be available at a fabric store?

Here's a link to the Death Star II build up on SSM.

Thanks for the ideas guys!

I was reading up on the DIY photo etch on this site and as it so happens, my local electronic store has everything except for the brass shim stock.... I can get that at my local auto parts store.

I think I might try the technique for my Death Star 2 build.

Hello all, I need an alternative to Photo Etched screen, but just as fine. I'll need large amounts for a project that I started lately (link below left).

You can also look for a small world globe. There are some that are made out of plastic, and you can pull the plastic film off. I picked one up from Craigslist for a Death Star II project.

I made molds from scratched styrene pieces and it worked out well. I also use Lego to build a reservoir and place this on a small sheet of styrene and make my first pour.

My greatest purchase was a book by Shepard Payne,... How to build dioramas. It has a section in there for mold making and casting.
