I wanted to check with you guys first, I plan on resin coating the inside of my boat to seal it against water damage. It is mainly a balsa boat with some hardwoods. The twin Graupner motors are installed already, and there are no electronics or wiring to get in the way as of present.
 I don't plan on clothing it, just sealing it with resin.
 Also the house and main deck are currently in white primer. Should I resin coat these too, or just seal up with some good enamel?
 I already fiberglassed the hull with one layer of cloth and a good healthy layer of resin (no airbubbles) and it looks great. With some sanding, it will be ready for finish color, which will be white with a red bottom.
 The vessel is an oil crew boat.

I normally seal the interior of all my wooden hulls with resin, just in case any water gets in. As far as the deck and superstructure go, as long as they were well primed and painted you should have no trouble.

Michael - you have noted that the hull external is glass & resin & hence you have the mechanical strength, so yes just resin on the internals would be OK.......the only problem is that thin resin has little resistance cracking if bent + during the curing process the resin will slip down to a VERY thin 'thickness' especially on near vertical surfaces

One way around this is to use sections of 50 mm wide woven glass cloth....it was designed for use in the building industry to reinforce gyprock internal wall cladding @ corners & joints...refer the attachment...it is also self adhesive on the inner surface & makes positioning very convenient

Even though the filament strands are only 0.2 mm in diameter.....you end up with thousands of voids that retain the resin..... Derek

Derek, I suppose it would depend on how thin the resin was, I've found that even a thin coat will waterproof the wood.

I like the look of that roll of coarse weave cloth, where did you get it?

Bunning's Warehouse Peter - surprisingly in-expensive too...I also used a double layer under my boiler insulation planking to stop any potential of plank discolouration @ 150 degrees C etc -

With my long suffering PS Decoy build  I wanted to retain the cedar planking external detail on the hull...so coated the externals with Cabots matt polyurathane spray. but reinforced the internals with two layers of the woven glass cloth between frames & then a liberal coating of resin & hardener.........Derek

Bunnings - of course - where else?  Thanks, Derek.
