Ah. I use a two-part polyester-based resin from MB Fibreglass' eBay store. Epoxy resins are a different thing entirely.

What is the working time on it?
Bondo brand fiberglass resin has a working time of about 4-7 mins.

Stock answer, I know, but working time is highly dependant upon a number of factors:
- How large is your batch? Larger batches may cure more slowly.
- How thinly are you spreading it? Thinner batches get more access to local heat, which accelerates the curing process.
- What's your resin/hardener ratio? A 'faster' batch (with more hardener) will cure more quickly - at the risk of cracking due to shrinking.
- What's the local ambient temperature? Hotter local temperatures (a hot day) will accelerate the chemical reaction fuelling the curing, whereas a colder day will adversely affect the cure time.
Honestly speaking, most polyester resins (of which the Bondo brand is a type) have more or less the same chemical composition, meaning they'll feature roughly the same working time. I'd still urge you to work in smaller batches, naturally, but if you're finding that your resin isn't curing properly I can suggest aiming a hair dryer at your piece - or, constructing a 'hot box' out of a fan-assisted space heater and some MDF.
I was able to find this on the forum
I ended up purchasing
From montana paints storm, it's close enough for my use and it is awesome paint
If you are trying to find the color code to match the paint this should help:

I absolutely love it when people make functioning 'things' out of costume and cosplay props, so this is fantastic.
From first-hand experience, Apoxie Sculpt is magical. You're gonna have a good time with that stuff. You'll end up mixing a lot more than you need the first few times, but you'll eventually be able to judge how much a particular detail or shape is going to need.
Another method you might want to try is just using styrene sheet for flat details and sharp angles. It's just a lot easier and will end up being cheaper than using a ton of your Apoxie Sculpt.

I've never heard of Styrene sheet. I looked it up. Do you mold it with your hands like the apoxie? Does it stick or do you have to use a sort of glue with it?
Thanks

Here's a link
to the styrene I buy. It's literally just rigid plastic sheets. You can use it to form curves, but it's mostly used for hard edges and whatnot. You need super glue or a model glue to adhere it to itself or other surfaces.
