drilling into Kevlar

Hi guys

I have just bought all the gear to deck out my kevlar sea kayak and need some advice.

I have worked with fiber glass allot.

Is there much difference in drilling kevlar?

Is there something I need to do or be aware of before I get excited and start drilling holes into my boat?

Another way
Was taught when drilling hole thru cored decks which most manufactures skip due it being labor intensive; drill an oversized hole. Fill it with resin and drill again with the correct size. This will stop water seepage.
