Under the waterline steel filler

[JSP]

Just found a crack in the stainless steel Keel guard. I know epoxy filler will fill this and bond to the steel (according to what it says on the tin). But being white it wont look to good.
Any ideas what else I could use? It's non structural so just needs sealing.

These any use?

What do you mean "a crack" is it a gap between two pieces of SS or a physical crack, where it's hit something?

If it's a physical crack then pop it down the welders to get it TIGged up. Will only cost you a couple of quid (probably cheaper than a tin of epoxy) and shouldn't take but a few moments.

If it's a join then any type of marine sealer/epoxy will do, you can get most colours these days or even use clear stuff.

Thanks for the suggestions everyone.
Hightower,
it's just a small crack due to hitting something. Only very small crack and the steel is very thin. Just want to seal to keep the water out really. For an easy option I don't s'pose sikaflex would do it? or is it no good for under water? Hope so as I would like to add a seal around where it joins onto the hull too.

Is the stainless likely to flex? If so the Epoxy might be no good as it can get brittle as it hardens

[JSP]

Yeah very easily flexes Andy. Could do with a flexible sealant really.

Use Sikaflex it sticks like sh1t to a blanket and will totally seal most cracks.

[Hightower]

Then either Sikaflex it as already stated of go the weld route. I'm positive that the weld route will be a more permenant repair that won't cost much at all. Certainly no more expensive than a tube of Sikaflex.

Everyone goes on about sikaflex but which one - it is a brand name - there seem to be loads of different ones!!!
