I need to re-seal my three Vetus alloy framed deck hatch’s to a GRP/gelcoat deck.
The grp molded cabin top plinth has developed gelcoat cracks from screw fasteners for covers, drawing rainwater along and up slightly to the failed, cracked sealant and down into the cabin.
I will of course repair the gelcoat cracks, but not decided on which sealant to re-bed the hatches.
Some say Sikaflex 291, but don’t really want the full adhesion factor, or a silicone?
Wayne Canning on YouTube suggests Dow silicone 795?
What have others used successfully?
TIA
