I've yet to build a chassis but I have a project that needs it (I think I'm scared to pull the trigger). So I've looked at quite a few YouTube vids on it so that's a good way to go I think The candle method is popular on them for heating the styrene. I also suggest searching the various forums. There are a few tutorials out there that go into detail that I've bookmarked for myself. Good luck Justin.
I have never had a problem with resin casters not sending product on time because I only buy from casters who have a history of good comments on the forums. I had one body that didn't show but the caster sent a replacement within days, and I still had it within 3 weeks (thanks Altered States). Altered States, VCG, Calnaga, Competition Resins, M.A.D.
I've got Norton 360 and it checks internet sites and shows a "This page is safe" when I checked it out. Usually if I go to an unsafe site Norton will block it. Now I don't know what other junk like ads they may throw at you though.
