Rub Strake alternative material in sheet form

Hi,

Does anybody know of a sheet rubber product that I can use in place of rub strake? I need a 2'x2' sheet of it for the nose of my Zodiac. I'm in the USA. I have had no luck finding the basic gray material that was used on my Zodiac. I even contacted a UK dealer or two but they never got back to me after the second email. Color not important as I will hopefully go with a big enough sheet to make it look OK.

Thanks,
Jason

How thick does it have to be? Most rubrails are EPDM rubber (Ethylene Propylene Diene Monomer); I'm considering to order from technorubberind.com however they don't seem to sell sheets. Their rubrails are specifically made for sib/rib... and cheap... 80ft@ 3" for about $200. A quick google of "EPDM sheet" tells me 1/4" 40sq.ft will cost you about $100... that's in the form of a gym floor mat ... same material; just find the right finish, smooth, glossy, whatever... I'm all for using materials other than their build purpose...

Yeah! the EPDM label is what I was looking for. I had no idea what the type of rubber was and there sure are a lot of them. Thickness isn't important, 1/8 maybe? 3/16?

I cut most of the strake off the bow section of my zodiac repairing holes and figured I would just slap a big sheet over it rather than thy to replace the old material. it needs to be 18"x18" or so.

Thanks,
Jason

Here... I'll make it even easier for you... they also have Neoprene which is (I thought) what the backside of Hypalon fabric is anyway... though EPDM is more durable I think... click here! or click here! you just use the standard 2K hypalon glues for it... enjoy, Peter

Sheet EPDM is available (I think) at McMaster-Carr.

thanks guys! Any idea on the right hardness for this application? I imagine it's medium to meduim hard (40A or 50A) at the most. Seems like the hard options would be too inflexible.

Thanks,
Jason

Sounds right to me. Though with a proper glue job, I doubt it would be a problem either way.

I would think harder than that would be ok as well; It's still EPDM; it's not like harder means it becomes a hard brittle sheet suddenly... in the end you're only trying to bend 18" over a 50cm dia tube... on top of that; the softer it is the easier it will scuff and thus go ugly on you I'd think...

i ended up emailing the technorubber people and they were willing to sell me a small amount. Very happy!
