Hardening my pepakura piece?

[redkirby01]

Hi, I'm pretty new to this pepakura stuff (only been trying it out for 2 months) and I've done a few small projects with it like masks and little props, but now i'm trying to make a full scale helmet for my red hood cosplay and I've kinda come into a stop with my project. I can't seem to get the helmet strong enough so that it's not bendable. So far I've coated the outside with resin, coated the inside with fiberglass and resin, and I've even added another coat of resin to the outside. A few spots of the helmet have hardened really well, but some parts are still a little bendable. Should I add more coats of resin? Or am I going about this all wrong? (sorry if this is the wrong spot to put this post, I just started searching around this forum and I couldn't find an answer to my question)

Perhaps more fiberglass? And before you get jumped on for it, this could have been asked in the "Help for Fiberglass and Resin" sticky
I just got done resin and glassing my helmet a few days ago and it's literally rock hard. Like a motorcycle helmet. If it isn't that hard you did something wrong!

Thanks! I added another layer of fiberglass to the inside of the helmet. I guess i'll find out tomorrow if it worked. I don't know where I could have went wrong though. I followed the resin/hardener drops ratio on the can. (10 drops of hardener per oz of resin)

(also, sorry for not posting this in the sticky)

If an overlapping layer of fiberglass isn't enough to make the helmet hard enough you might want to try a layer of rondo to the inside.

Not to offend but did you bother reading that introduction guide? It would have helped a lot and point you in the right direction

 

[redkirby01]

I read the introduction guide (saved it to my computer) and I already knew most of the stuff on it from watching youtube videos tutorials/ different articles on google (2 months ago-now) I just wanted to know if other members were familiar with this problem willing to help me out a bit. The resin/hardener ratio always seems to mess me up for some reason...

Sorry and if you want your peice really hard do what kryios said and slap rondo up in thur!

 

[Kryios90]

if the resin/hardener ratio isnt right the resin will either take longer or possibly never harden completely depending on how off the ratio is.

 

[redkirby01]

It's fine! I will definitely try rondo if it doesn't work out.

Turns out the 2nd coat of fiberglass/resin on the inside worked! Thanks everyone!
