So as all of you have basiclly watched me learn the art of glassing i have been able along the way share tid bits of things i have learned from others and on my own. With all the work i have put into this boat its wise to protect your investment by not cutting corners in the end. When cut penatrations in your core material you leave it vunerable to water unless you protect it properly. Hot coating raw core edges when you drill holes is very important to keep your boat from rotting. Heres somethings i have done to every hole i drilled on my boat
This hole for the rod holder was treated with 2 hot coats of resin that was reduced 10% with acetone to allow the resin to penetrate the core wood easily.
Here is another pic that show a counter sink bit i purchased. I use this bit to to keep the screw threads from pulling the fiberglass up and it also allows the sealant to have room in the counter sink void and not squeeze it all out when screw your hardware down. Also you will notice the white coating, thats a polyurethane based aliphatic roof coaitng by SRC. Its basiclly liquid rollable 3m 5200.
