Here are some links to web pages that discusses Future and modeling.

It also make a great clear coat. If you need to remove it you can take it off with rubbing alcohol without damaging the plastic.
I joined Derby Talk and saw your 2009 posts about designing and building a Speed Racer Mach 5 car. Unfortunately, that thread is no longer active on Derby Talk so I can't see the images you posted to the website. Can you either re-post the images to Derby Talk or send the images to me directly? Much appreciated.
