John,
I'm not a big fan of the Marine Tex. I put it in the same catagory as Billys Mays's Miracle Putty!! Not good for doing most jobs because of it consistency. It's too thick to really get into the underlying surface to prime for good adhesion.

For the gel repair, get one of the gel repair kits at the marine supplies or on line. Go2marine is a good source. Mix the coloring pigments into the base in very small amounts. I use the tip of a tooth pick until the color is correct then add the hardener. On vertical surfaces you may need to put a piece of tape over the gel to keep it in place until it sets up. I also tape around the repair area so when you hard block wet sand the new gel down to level it, you don't sand the surounding area. Get it down to the level of the tape, remove the tape and finish sand/buff. I like 3M fine line tape. It's thin and water proof/solvent proof.

Stripped screw holes can be filled with a epoxy. Even the small double syringe type you find at the hardware is fine. Fill it up, drill a new pilot hole and run the screw back in. If you can get to the backside, using a machine screw, washer and nut is even better.
