Upholstry help?

[DooC180]

I am reupholstering my c180, the first 5-6 panels went well but I ran into one cushion that seems to have an exceptionally hard base! My staples are folding up like the lwtter "M" and besides looking ugly I afraid they will rub the fiberglass. I can take the same stapler/staple combo and go directly to another panel and it works fine. Have tried pressures from 60 up to 120, tried warming the plastic base with a heat gun and I cant get them to penetrate without bending- very frustrating!

Anyone come across somthing similar or have an idea to work around it?

I've tried 1/4 monel (break/break), 5/16 stainless (bend) and 3/8 stainless (bend).

It's actually both rear seat bases, the plasticker is def thicker/harder than the others which are a bit flexible.

The factory staples are a thin gauge. I'm guessing by the time I source another pneumatic gun and fin thin stainless staples I could probably just pay the local shop to wrap the 2 cushions for me since I already have covers.
