I agree with BF. Regular epoxy may melt your gauntlets. Try the cold cure epoxy pictured at this website <A HREF="http://www.mec.ca/Products/product_detail.jsp?FOLDER%3C%3Efolder_id=677245&PRODUCT%3C%3Eprd_id=739031&bmUID=1079417575949
" TARGET="_blank"> Cold Cure Epoxy </A> - it worked great on my Ruffkintoy gauntlets. There was no distortion of the styrene. Mind you I would double check on a sample of your own peices first before taking my word. 
The website is for a Canadian Outdoors Co-op and the epoxy is for boat/paddling repairs. I posted it for reference, I am sure there is something similar everywhere. It is used in situations where using regular epoxy is not ideal (sea kayaking, mountian lakes etc). Although, I do think they ship worldwide.
It is odd actually, I shop here all the time for my other hobby (camping/backpacking) - who would have thought my two (seemingly unrelated) hobbies colliding. 
Good luck,
