Fiberglass Issue

[marbleyes]

Hello everyone,

I have a 2006 1851 DC. A few years ago I modified the space below the left console for 3 batteries for a 36v bow mount trolling motor. The batteries at the time I used were not the maintenance free. Am currently using sears agm. The problem I have found, as you can see from the pics is the fiberglass is exposed. My question is, is that from the acid that leaked from the batteries? And if it was the acid, is it just superficial? I poked a screw drive around over it and it was solid. What can I do to fix this problem?

If it were me I would grind down all the bad stuff to wood or fresh glass then glass in a couple layers of csm . Making sure no rot first .. Then I would cut some plywood to to cover the area . Glass that in with csm . Then screw your battery trays down to the thick plywood pad with screws short enough not to penetrate the actual deck .. I would paint some gell or bilge paint the whole area . Plenty of 5200 on all the screws ...

I would just put some epoxy paint on it and go fishing.

I honestly can't see how the battery acid ate the resin and not the glass. I mean there is almost nothing that eats polyester resin. So if you can wash the area with TSP and neutralizing any battery acid that may be there, then you could resin the exposed fiberglass and happy boating. If the area is still solid, the added polyester resin will cover the expose fiberglass and give you a nice smooth surface again... IDK :noidea:

Thanks to everyone that replied. Looks like a project for after the season.
