Hi Fett X,
Depends what your gauntlets are made from. My set is vac' formed styrene, and to secure the 'outside' seams, I used super glue reinforced with 2 small screws/nuts (for each gaunt). For the 'inside' seams, I used the industrial strength velcro. As long as the surface is clean, and you let it set-up per the instructions, the velcro works really well.
