Are there other RTV molding rubbers ?

[KING_MEMPHIS]

Hi Guys

As a Newbie I've been lurking around for a bit - but now I finally jump in:
For the last couple of weeks I've experimenting with WS RTV moldings for for Tunnelportals and retaining walls. Seems to work outfine; but I was wondering if any of you have any experience with other RTV rubber than the one for Woodland Scenic ? Preferably something cheaper

Well, lets see, there's Micromark, who has a full resin modeling kit. There there's Bare Metal Foil:
Mold Making Materials - Bare-Metal Foil Co.

Polytek, where I get my stuff from:
Polytek- Mold rubber, liquid mold rubber, mold making

And if you google RTV or Resin mold you'll find more.

I'm not sure what RTV stuff is, but if you, say, have a tunnel portal, and you want more of them, I used stuff from Hobby Lobby. Half a dozen or so coats and Voila! I think I got a half pint jar and have made several mold. Still have some left (if it hasn't dried up on me)

RTV, Room Temperature Vulcanizing, basicaly means it cools at room temp.

Smooooth-ooon - sounds reeaally nice ! :-D

Thanks for the welcome, Mikey. It's a great forum here.

And thanks for the usefull links. Especially the Polytek- instructionvideo is great. It's fine to read about the process - but it's even finer to see it performed live. Though it seemed to be targeted to industrial purpose rather than making tunnelportals in Z-scale ;-)
Well, if I downscale the process - it will probably work.
