[Chuck Most]

the 305 works for general models since most guys dont whack their built display models against the wall.. i hope..

I don't know- that Metro of yours can take quite a beating!

Hi Mike, you are correct.

However

the purpose for owning a pressure pot is you can pop all your airbubbles in your RTV to a microscopic level

You do not need to vacuum or degas your silicone if you have a pot. Not sure how it works for car bodies, but doing 1 and 2 piece molds for wheels, suspension parts and other items, pressure is wonderful.

My resin experience is a shot in the bucket compared to the guys who have been doing it for over 6 years, but in my years of casting, letting RTV cure under pressure has been amazing.

Make yours molds as usual, mix up your RTV, pour your mold..throw it in the pot and let it cure under pressure.

Mine will cure in less than 10 hours, then I'll bake the mold for a hour at 150 degrees to finish it off.

Ahhhh, I didn't know you could cure RTV under pressure. I thought you could but didn't see anyone make mention of it. I've had good luck w/out one so far, but may take a stab at it now.

Thanks a whole bunch Ryan!
