So this boat is in really great shape in and out. Still has the dual Force 120s oldies running great but the deck has multiple stress cracks all around the edges. I want to fix that, I do believe the color is white don't know if it's a particular shade of it. So I already have some Total Boat Wet Edge one part white Top Coat and primer. I was going to use that to paint the dash board area where I closed the hole where the old fish finder went using epoxy, was going to fair it and prime paint it white. I am changing the gauges from the 5 inch obsolete, to the 4 inch new ones. Interior is immaculate.
The previous owner also fixed the transom rotted wood and installed composite pourable compound forgot which company, but the back motors are no longer showing any flexing when raised up and put pressure on.
Watched all of Andy's Boatworks Today videos and others also read about the fiberglass options, I can buy the Total Boat Poly laminate resin and grind the cracks deep to the core fiberglass use some carbon based matt material and reinforce, use white gel with wax to cure after. Can shoot it or roll plus tipping on a limited time frame. Also already have some 3M poly resin and some neutral gel. I don't have any color additives. Have a friend with a Bodyshop maybe they can make some colors but I think here in Cali the base coat is water based, not sure if it's compatible with gel.
Or I can use what I have West System 105 and 205 plus 206 hardener with the same matt which is compatible with both types of resin, primer and paint with polyurethane white. I have a gallon each.
Have no clue which option is better. Being inside I don't think it matters it's white and it's on the side. But I want it to look nice.
also have to repair that bow pulpit which is cracke on the side where the plastic roller goes, even though there is aluminum reinforcement there. I think it's resin, don' know for sure.
So, thanks in advance guys for any help.

Test drill the stringers to make sure you don't have structure issues.

I buy all my fiberglass supplies from the local supply house that also makes their products. Having used both poly and West epoxy. Poly is faster and easier

Thanks for responding.
Can you be more specific on that? You're talking about drilling behind the cracks at the stringers by the transom? I can get to the stringers through the battery compartment on both sides. Trying to learn on how to do that. Not versed on it all yet but getting there.

You will want to take a drill bit, I used a 3/8 inch, and drill through the fiberglass in various spots along the top of the stringer. You are looking for water damaged wood and water trapped inside. Do this every 2 feet. You don't need to do deep to see if it is rotten.
If no damage is found, fill in the holes with resin/chop strand.
If damage is found, time to cut out the bad section or whole stringer for a propper repair.
You can also see if any bolts that are mounted in the stringers can be pulled out by hand. That is how I found I had damaged stringers.

I would check along the whole stringer, from the transom to where they end. Water only needs to be in one area before it spreads like cancer.
