Smooth on mold max Stroke vs rebound 25. the cost is in favor of stroke. The plan is to make a mold of a GB Proton Pack and then use a fiberglass mothermold. What does your experience say are the pros and cons for the cost savings. |

I assume both these products come from http://www.smooth-on.com/ , though I couldn't find them on the tech. data sheets. If so, give them a call. You'll pay for the phone call... That's why I use www.alumilite.com , their help line is an 800#.
Fiberglass will work for a tool if it's not allowed to get too hot. Polyester resin doesn't handle heat very well, and it'll need to be thick enough to handle the load. Fiberglass molds are not production molds.... I'm sure they'll work for short runs if allowed to cool between cycles. That's about all I've got..............Fredo
p.s. Cheap molds don't live very long. _________________ If someone has a gun and is trying to kill you,

What do you plan on using for the final mold? Also, are you going to vac form the final product? If you're vac forming then Fredo has good advice on using higher quality products designed for the heat & pressure. _________________ DougN - Just in case you're wondering, I got my "rating" legitimately... by posting aimless drivel, useless advice, and pointless questions. |

So the final product is laid up fiberglass and not vac forming. You won't have to worry about heat and pressure since it's not being vac formed.
Hopefully the guys with more fiberglass experience will chime in.

I am just concerned with the 2 types of brush on silicone. one is 10-1 and the other is 1:1. cost is significantly different and i want to know if the results are the same. |

The difference is that one of them needs an additive for vertical application. http://www.smooth-on.com/tb/files/Mold_Max_Series_TB.pdf ........Fredo _________________ If someone has a gun and is trying to kill you,
