I'll try to remember to ask what that stuff was. I unfortunately no longer have a source for it.

KEN
I bet it is HMWPE
Or more frequently called HDPE
High density Polyethelene
It is readily available in sheet, rod, bar and tubing forms.
High abrasion resist, low moisture absorption, rigid, slippery, easily
machined, outperforms nylon, delrin and similar. And way cheaper.
[EG hockey rink boards are often surfaced with it.]
I have used it by the 'gross' in lining machinery paths in many apps.
Can be gotten at any plastics supplier, being a very popular and inexpensive
plastic.
Usually white but other colors can be found.
Made from petroleum; unfortunately it takes near 2# OF petro to make 1# of HDPE.

I welded a pair of mini rollers to the bottom of the frame rails, similar to these: http://www.rvpartscenter.com/ProductDetail.asp?PID=28607&SID=25&DID=109&CID=257. They are very low profile (I was afraid they'd drag too often if they were bigger), and have zerks to keep the bearings greased. I don't know how anyone could drive a GMC without them. I absolutely could not get into my driveway without them. --Vince

I also have those mini rollers bolted to my frame rail about 30" back from the bumper. I have drug them big time on several driveways and they are absolutely indestructible. They make a lot of noise when that happens but the rear of the coach is still undamaged... Bryan '76 Eleganza TN

From your description that sure sounds like the stuff.

I was trying to make up my mind whether I was going to recommend HDPE (HMWPE) or its more stout brother UHMWPE (Ultra High Molecular Weight PolyEthelene). The UHMW is somewhat more expensive but I have put it places where nothing else would last and it didn't even care.
If you should go to make up something out of either be real ready to cut it. Don't even try to take small cuts or de-burr it later, it just doesn't happen. A light cut just slides off. It will try to "Hog" almost like a soft brass.
I'm still trying to decide if I love this stuff or hate it. No matter, when you need something that will not wear at low speeds and temperatures - Pick One.

Matt,
Could this be the same stuff that is on the boom sections of the cranes we
use. It is used as rub blocks where the sections telescope into
each other? We spray them once in a while with a dry graphite.
Very hard and durable. If so, I think McMaster Carr carries it in pieces.
Thanks,

I'll have to offer to replace the new rub strips...and carefully dispose of
the old ones.
