Here is a good question. On Saturday I put 3 rodholders in my transom cap. My transom cap is solid fiberglass/plastic, no wood, no coring of any kind. Here is a pic;
Please be aware that the orange stuff on the plug I took out of the transom cap is just the paint from the holesaw, it is all composite material. I put 4200 all around the flange of the rodholder so absolutely NO water is getting below this rodholder. My question is, should I have sealed the raw edges of this hole?
