I get it at Medards, but a little research in your area might locate other sources. This is what it is:http://www.menards.com/main/building...4441877488.htm
I got the 1/4" sheet for about $60 a year ago. I don't know if the price has gone up, but it's now is double that. The 1/8" sheet will work fine and I would have gotten that if they had it in stock at the time. It has a textured side and a smooth side. I put the smooth side up but I doubt it matters much.
Attachment isn't particularly difficult, just a little tedious. If you have buddies interested a 12" strip is likely enough, so you could get 4 pieces out of a 4x8 sheet. I did 16" for some reason. I marked the center of each side tube and centered my strips on those marks. This put the bolt heads out of play, though they shouldn't affect the tubes even if the boat were sitting on them as they're well rounded and smoothed off.
I attach an 8 foot strip with 8 carriage bolts. 4 in each corner and two on each side. The key is to allow it to shrink and expand (which it does a lot). If you just screw it down, it buckles up when it's hot. So what you do is cut the 8 slots parallel to the long sides in each piece about 2 inches long. To do this, I lay out the slots where they won't interfere with anything under the decking (cross braces, etc.) then drill out each end of the slot with a drill bit the same diameter as the carriage bolt. Then mark and cut lines that connect the outer edges of each hole, creating the slot. The carriage bolt will then hold (like a wrench) in the slot. Drill holes in the center of the slot through your existing decking, add a fender washer underneath the whole set up than a nylock nut. It helps to have some one holding down on the carriage bolt while you tighten it. Just take out the play in the bolt but don't tighten it so it squeezes the hdpe to the decking. Being slightly loose will allow the sheeting to expand and contract with temperature changes but it will be held in place. If carriage bolts don't work with the 1/8" sheeting (the shoulder of the bolt will contact the decking) just get wide pan head screws and tighten the same, you'll just have to have two people - one to hold the screw and one to tighten the nut (our vice versa, what ever works). I think the carriage bolt should indent into the decking so, I'd suspect that they'll work but haven't tried it on the 1/8" to be sure.
When this is all done you have a very slippery strip down each side and something more grippy (depending on your decking) down the middle. If you wanted more grip in the middle, you could then line-x the middle or add grit to paint or go the deckover route, or... whatever you like really.
If you just want to test how you like it, just screw it down where you think you might put the slots down the road. I ran mine like this for a year and it works fine, but it doesn't eventually stress the screws and they break and it bubbles up in between looking kind of half assed. A buddy of mine tried numerous different attachment methods on his and found the carriage bolt to work the best.
Good luck to you and thanks for being patient. I didn't want to type all that on my phone!
