Drilling through fiberglass...any advice?
Hey all, I need to drill a hole in the top deck next to the tower mounts to route my tower speaker/light wiring into the bulkhead behind the observers seat. Need less to say I'm paranoid at the thought of taking a drill to my baby. I've read several tips online but not sure what to trust. Most say apply masking tape to prevent splintering gel coat. Also, start with a small bit in reverse slowly to wear through the gelcoat , then dill away, increasing the bit size slightly each time. I'm thinking a 1/4" to 1/2" would would suffice. Any help?!?
Thanks!!!

Masking tape does work, make a small pilot hole and use a good sharp drill bit, I've drilled holes all in my boat and never had a problem, except drilling through the bottom of the hull lol

pickle gave the right advice. I've drilled holes for a wake plate, deflection guage and four cleats. New sharp bit, masking tape, patient reverse drilling through the gelcoat and finish 'er off.
You will be surprised how easy it is.
I have found that for larger holes a "hole saw" type bit works really well and leaves a very clean finish also.
