I am jumping ahead in the boats process to group these blogs together. At this point I have already glassed the hull. When I got to the drain holes I made an "X" cut and folded the glass in the hole. I then let the epoxy dry and sanded any rough spots. When I was done with the first fairing I add filler to the fairing to make a paste. I then installed the brass tubes.
Here is a look after sanding.
