What you use is pretty much up to
" personal preferance " kinda' thing..
Me, I have ALWAY'S used Por-A-Kast
product's. Some like Smooth On, some
don't.. Can't say I've read much on
Alumilite stuff though ?
BTW,if you DO go the Por-A-Kast route
watch which type you buy ! I ONLY use
the Mark II stuff as you have a little
more working time with it. About 2 1/2
to 3 minutes... The Mark I is VERY fast
setting stuff, about 1 1/2 minute's !!!!!
Only good for SMALL mold's !
Just so you know..
