is it possible to shave kevlar?
got a problem where due to my (very  ) second hand body work, theres a few cracks need repairing. got a bit over enthusiastic with the flap wheel in
the grinder... well, just enough to get rid of all the cracks and flakey bits. but thats left bits of kevlar hanging out. no problem i though,
fibreglass over it. when i sand that down though, theres still kevlar showing through.
pics to follow soon
what can i do?

Are you sure it's Kevlar? We cut kevlar with ceramic tools otherwise you end up with 'shaving brushes'. If it's body work them
I would have thought it would be fibre glass in which case wet and dry will do the job.

Try using brand new surgical scalpel blades, Swann Moreten supply them to model shops etc.
Good luck, Kevlar is a bu**er

lol, i know... pretty much every panel has cracks, many of them are actually split, which is fine because its usually inside the panel and can't
be seen from outside.
i'll give it a quick shot with a disposable razor to see how it goes (nothing to lose lol) for now, but do you mean use the scalpel like a cut
throat razor? should i do it dry or with water or soap (or even shaving foam lol)

Definitly dry and try to support the fibres when you cut them, a carefully applied piece of glass would be worth a try. If you can cut them below the
surface you'll be able to fill and sand afterwards.
You have my sympathy

I would approach it another way - sand back the filler you put on and lightly run a blowtorch over the kevlar strands to melt/burn them back.
Then cover with filler - of course doing it on a test piece first might save you some grief and/or a major conflagration.
