Best filler?

[Sniper]

I need to do some light filling of the planking below the waterline - just scratches and raised grain really, so nothing too deep. Above the waterline I always use international 100 trowel filler which is excellent but apparently not suitable for below the waterline.

What is the best thing to use? I suppose epoxy is a possibility, but it seems a bit of overkill for what is basically just cosmetic fairing. Would the trowel filler work, or would it fall out?

IF well sandwiched between Primocon.......Polyester filler is fine, IF applied thinly and IF primed over. Quite good enough, sand nicely, and quick as you like.

Thanks Nick; that's what I hoped. I have a first coat of primer on and will no doubt add several more in between fairing!

I assume, that you didn't mean car body filler, as it's porous. You can mix cab-o-sil or the like into reacted resin, or even talc. Use microballoons for fairing, or even just add wood flour to reacted resin

Plastic Padding make an epoxy marine filler which would be much better than poly ester filler, mixes, spreads and sands just the same.
