I am sorry that I can't help you out with that. Maybe someone else has found something? I really had to do a lot of research to find that stuff here and the only way to get it was through the internet.
It would be great if someone else has some experience our even pictures to share here. I'm sure building indoors is an issue for a lot of people.

new member to the site and lurker for the past 5 days. still trying to figure out how to make pepakura ironman helmets but this definitely helps.
i have access to work outdoors but much rather work indoors so definitely going to steal your methods. so far this is the best tutorial ive come across for step by step instructions.
great job. looking forward to following your progress.

Have you tried slush casting with acrylic resin? How did it go? Also what's the cure time? Thanks.
I did make a test mold using silicone caulk and slush casted with acrylic resin., it turned out pretty good but it is kinda heavy. I can post a picture of it tomorrow. The pot life of this stuff is 12 minutes.after 20 minutes it is cured to a point where it isn't tacky any more.I usually let it sit for 2 hours before I start working on it again.

Okay guys... the last update has been a while in the meantime I have been pretty busy. As some of you wanted to see if a helmet could be slush casted: I made a quick mold with silicone caulk and molded the faceplate testwise...
The mold was not very good but the resin captured the detail just as good as polyurethane.
After I had finished the details I made a real mold using the right silicone and the result so far is this:
For easy disconnecting the faceplate I had separated it from the main helmet in the molding process already.
After I cut it up, sanded and primed it, this is what it looks like at the moment. I took the picture while the paint was still wet :facepalm

Here's a link to my thread. I've been trying to keep it up to date as I can.

Hi everyone. I'm up here in Calgary Alberta Canada and thought I'd mention what I'm using. I live in a 2 bedroom condo and winter pretty much eliminates using the balcony. I looked through RPF and Smooth Cast was suggested. It works great. I used paper towel torn into strips for the inside one the last 2 coats. Worked perfectly. I was talking to the supplier here in Calgary about the project and he had a suggestion instead of bondo. Smooth-on free form sculpt. It's a sculpting epoxy dough. Comes in an A and B you combine in equal parts and smooth it on. It's a tough dough and my first coat went on kinda thick but it sands very easy. I'm actually using a hand file and 60-80 grit sand paper to knock it down. It really does work great.
He also has non-toxic materials for casting molds etc if I choose to go that route.
I will be putting up a complete post once I'm done the helmet. I'm taking pictures as I go.

I am glad this helps some of you guys out! I haven't come up with a solution to cast stuff without having to use toxic resins. The Acrylic Resin is great to work on a Master but it adds quite some weight. I have seen some "Bioresin" but that stuff is really expensive. I'll keep you guys in the loop!

The Smooth Cast I mentioned in my post is actually intended to be used in molds. it's non toxic and works fantastic. I don't have the space to try to make molds or anything like that (yet) so I just paint/pore it over the helmet. Sets up in 7 minutes or so.

Talshadar - what's the approximate price for the Smooth-on epoxy dough you mentionned? I'm curious to know if it's in the same price range as bondo? or if you are paying a premium for the benefit of working with something non-toxic?!
Dirtsen - please keep updating your thread! I`m new to pepakura, but I am VERY interested in finding alternate ways to strengthen and finish Pep parts.. especially if it's something that can be worked with indoors! Thank you for experimenting, for the sake of all of us!

I use wood filler instead of bondo. It is a 1K product so you don't have to mix it, it hardens fairly quick, you can squirt it out of the tube in the amount you need and it sands like a charm. Also: it is sooooo cheap! Only downside is: it can be brittle. I used it to make a master that I later molded and casted so was not too worried about that. But my master is still sitting here without a chip.
A great start to working indoors are always foam builds. I recommend you start with that. If you are going with paper-pep:
1. Use cardboard paper, get some epoxy resin that does not come with toxic fumes (There are a lot of them out there, I found and used one brand).
2. Soak you paper model with the epoxy resin.
3. Get some acrylic Resin and slush cast the inside of your paper model, let it cure.
4. work on the outside with sandpaper and bondo (or in my case wood filler)
The problem is: sanding is a MUST! And there is no way you want to do that indoors. A Garage maybe (which I do't have). It is Winter here and my projects that need sanding are literally on ice right now. That is why I am not updating here so regularly at the moment.
But I encourage anyone who found something that is non toxic and usable indoors to post here. We and our environment can only benefit

could you do a tut for how you made the mold with silicone caulk? and I've been using aqua resin, it doesn't go on a cleanly and polyester resin, but a bit of sanding never hurt anyone!
