"Help!" for: Fiberglassing, Resin, & Bondo

Have a look at this: http://www.405th.com/showthread.php/...oduction-Guide

If you want a non-toxic solution, try Aqua-Resin. The basic steps will remain the same.

i've called and looked everywhere in my town no one carries it

How do you guys get Into small detailed parts with the bondo?

[BlertZ]

since i have very little time to go through 150 pages of intel i'll just ask my question.

when getting to the bondo application should the outside resin be sanded or not? Cuze i got a very smooth coat of resin on my parts and not sure if i should sand it or not?

[Abaris]

A fast and rough sanding will give the filler a better surface to stay, anyway any polyester based filler (which Bondo is) will stick perfectly to polyester resin.

Do I need a hardener for the fiberglass resin and bond? What if I dont use the hardener?

Yes. Think about it - why else would they include it in the package? If you don't use it, it won't work.

I`ve been doing some bondo on the helmet and been finding a lot of rough surfaces. Does I need to rebondo it again/just sand it?

secondly as u can see on the below of the helmet it`s does not fit on my head very much and this is my second build after I hardening it and the result on the shape is the same so does eva mat(or whatever they called it) could fix it?

Question on regards to bondo. If I'm trying to add details to a model (because the pepa model I had wasn't exactly the design i'm going for, so im accounting for that in bondo) Is it practical to take like, wire mesh (windowscreen) thats part of the fiberglass base, but the mesh comes to the surface and wraps around, and to make it so that when doign the bondo the bondo also has that to grab onto as well as the surface (roughly sanded) of the base.

Did you coat the entire helmet in Bondo? That's what it looks like, and if you did, you have A LOT of sanding to do. Bondo is mainly meant to smooth out corners or edges where needed, not to just slather over everything.

Simply trim out the base until you can fit your head through. Not sure how EVA foam would "fix" anything, but it does help to make the helmet fit tight and comfortably on your head once you get it on...

Possible? Most likely.
Practical? I don't think so.
If I understand correctly, you want to add parts that are not on the original Pep file. I think your best option would be to use cardboard to build up parts instead of mesh+Bondo. You can even use foam pieces, depending on what kind of stuff you want to add.

Note to everyone: Bondo is primarily used as a "detailer". It's a great product, but not the end-all-be-all material for armor making. When used the way it's supposed to be (thin coats, small quantities), you get good results. However, it's a brittle material when dry that does not offer much in terms of structural support. Yes, Bondo is a main ingredient in Rondo, but in my opinion, it's a shortcut method that simply makes for a more brittle/fragile end result compared to other things, like fiberglass.

owh so Bondo is used all the edges to detail the part not all of it. Thx man been worrying how much bondo would I use for the whole suit.
