I tried some RTV to make a mold for a part that I wanted to cast, and the RTV ADHERED to the part! I had to cut it off of my part, and then do some restoration to it! It was made by Permatex, I believe. A very horrible RTV experience!

I really need to find something reliable that I can create molds with, then I need to find a good resin. Seems like Spidey mentioned some type that was a 1:1 mix ratio...

The part that I'm trying to mold is plastic, so whatever I use needs to be plastic/resin/poly-friendly...

Any suggestions?

[QUOTE="Fetthunter, post: 9955, member: 131"] I tried some RTV to make a mold for a part that I wanted to cast, and the RTV ADHERED to the part! I had to cut it off of my part, and then do some restoration to it! It was made by Permatex, I believe. A very horrible RTV experience! :eek: I really need to find something reliable that I can create molds with, then I need to find a good resin. Seems like Spidey mentioned some type that was a 1:1 mix ratio... The part that I'm trying to mold is plastic, so whatever I use needs to be plastic/resin/poly-friendly... Any suggestions? :) [/QUOTE]
