There was a SI transducer mounted to the transom of my Falcon. I知 planning on filling the holes from the screws and want to make sure I知 doing it right. My plan is: 1) drill out the holes one size larger than the screw size 2) compressed air 3) clean with acetone and a q tip 4) compressed air again 5) fill with 610 epoxy 6) clean epoxy around hole 4) cover with masking tape 5) sand down excess epoxy after cured. I知 debating on leaving the epoxy unfinished (boat is hunter green), going over the epoxy with matching fingernail polish, or using gel coat. I致e never used gel coat before. Any advice?
