Vintage fiberglass helmets- Cyberman advice needed

[RobertHack]

I'll have a vintage(at least 20 years old, the previous owner wasn't certain beyond that) Cyberman helmet. It's resin/fiberglass. I need to cut out the eye, mouth and handle holes. Is there any special care or prep work I should do for an older helmet?

This is actually my first fiberglass helmet build and will happily take any other advice.

Thanks!

Only potential thing I can think of is that it might be a little brittle, but it shouldn't be bad. When you drill and cut your holes just be careful to start small and work your way up to the edges.

The fiberglass will hold things together so even if you do chip or crack something it's nothing a little bondo can't fix. Should be a pretty forgiving project.
