Yeah, Organic Vapor ones are the best and are mentioned all over the forum. With any project, always remember safety first! Good thing to see you're using your noggin! (Unlike oh so many new people on here) ^_^
I hear hot glue is bad to use because of that heat factor so I'm using standard Elmers school glue? I thought I'd just stick with fiberglass resin, being conservative with it for the first coat, or just use my spray on bed liner trick again. (My poor wallet will suffer for my need for convenience.) and then rondo for the helmet interior and detailing. I find rondo is better for detailing and smoothing than bondo as it gives me more time to work with it. I just add a lot less fiberglass resin than i normally would and a little less hardener. (I try not to add too little hardener or the bondo part doesn't set right and it's sticky forever.
Yea I haven't had too much problems with the hot glue coming undone, I just think that when it did happen I used more hardener to resin ratio, got it hotter that normal, its rare that i have a problem with it. since I always coat the out side of items where the glue is not present.
hopefully this is in the correct area, but i was wondering if bondo would adhere to PVC pipe or if there was something else i could use that would have the same sculpting ability. I'd be following the same rules of ceramics with it by scoring the PVC with a high grit sandpaper first, but would this help at all? just seems like a slightly easier method of building the cannon to Samus's Varia suit than just rondoing and using bondo to try to make a perfect cylinder. might also be an easier way to make it into a 2 piece unit for easier donning and removal.
thanks!
thanks!
what about PVC pipe found at like Home Depot? same rules apply?

Question. I just put some resin on the outside of a couple of my (smaller) pieces. It's been about a day and it doesn't really seem like it's done anything. I mean it's hardened and whatnot but it still seems just like paper. Is that normal? Does the extra strength come after I put some fiberglass on it?

If they can smell it, then it's affecting them. I know the fumes are strong, but frankly I'm a little surprised that they're making it into the house while you're in the driveway. I did Bondo work in the garage with the garage door open, and no fumes could be smelled in the house. I suppose you could put a fan inside the garage or nearby facing away from the house to ensure the fumes are kept away. Good luck.
This is pretty much normal. It may not seem like much, but the resin alone helps just enough to reinforce the Pep structure to support the weight of the fiberglass or Rondo (whichever you decide to use) in the next step. It doesn't harden it nearly enough as fiberglass or Rondo will, and it's definitely not enough to consider it "hardened" and ready to finish.

Thanks Spitfire! Also another question. I've made the shins of an ODST and I want to resin that next (as well as my chest pieces which are large so I'll include them within this question). Will the resin warp any of that? Should I somehow reinforce my pieces while they're drying?

There is always the potential for things to warp. Its better to leave supports on pieces when you are resining. It's good to try and reinforce pieces for fiberglassing too but sometimes leaving supports on and fiberglassing is hard to do.
I'd recommend, f you can, making some sort of brace or support that will let the piece keep the shape you are looking for. It can be as simple as a strip of tape across it to keep it bent a certain way.

Sounds good! Thank you sir.
(Note I said nearly >_<)Hard to say. I assume you're talking about the styrene smell. You can actually smell that before the maximum workplace concentration is reached, but then again, these thresholds aren't intended for homes with families and children and you don't have any reliable way of determining the actual concentration. The safest thing you can do is shut the windows.
And for the record: Smelling and being affected aren't necessarily connected. In this case it's probably safe to say that if they don't smell it, they aren't affected, but there are also things that you simply can't smell at all and that can ruin your health nevertheless.
Where? No idea where you are, so the generic tip is to try the internet.
Fibreglass? That question came up just the other day: http://www.405th.com/showthread.php...ssity-of-fiberglass-cloth?p=539309#post539309
Please do some research on how the whole reinforced plastic stuff works, that will give you a better understanding of what you can do and what not.
From the way you ask, I assume that you want to save every last penny. If so: Doing it right the first time is cheaper than saving in the wrong place, failing and starting over.

When I resin I notice small hard globs form when I paint the resin on the pieces, there are also more and much larger globules in the cup of resin, why?

That happens when the resin begins to catalyze and harden. I usually stop when I start seeing them because sanding down those resin globs can be pain especially when they are left in the grooves.
