Many of you have discussed ways to recondition scratched up BMW system cases. Here's one solution: Rhino Liner. The stuff is tough as nails and generally scratches whatever it winds up scraping against. I got a request to see some pics of my cases. I'll post one here and the rest in photobucket.
I love it!! I have the same bike, but recently painted it matte black. I'm thinking about the rhino for all the (formally) yellow parts and the oil cooler covers. I'm not sure what the temp rating of the Rhino liner is, but I'm not sure it would hold up on the valve covers. I doubt they would warrant it.
Is bug cleanup difficult?
Some spray on liners are soft and others are very hard. I'm guessing that the rhino is harder? What did it cost?
I wish I could take credit for this but it was the previous owner who had it done. He'd acquired the cases and mounts separately through eBay and they all had slightly different finishes and looks. Instead of painting he RhinoLined. It all came together and I think, looks great. Plus the finish is super tough. I did ask him about it though and this is one of the thinner coats that can be applied. Backing into my shed I've scraped against the door jamb as well as a table inside and both come off on the cases. I can then clean them up with a medium stiff brush and they come away with zero scratches and scuffs that you can see, and a brush like this takes off bugs without having to worry about scratching your finish. Of course the pebble grain finish helps mask any scratches you might get. It is quite hard but flexible enough that you don't have to worry about it cracking.
As far as particulars, I don't know if you've seen a heavy coat on a truck bed but it is roughly a half-inch thick. Way too thick for cases. This stuff is maybe a 1/16th. I think RhinoLiner can also be sprayed on in colors. Prep work involved sanding. Naturally the key inserts, handles, and backs were masked. Sorry I don't have any information on cost.
Valve covers would look gnarly done this way but I don't know anything about the heat properties of RhinoLiner. It might stay on fine, might not, you'd have to ask them. Either way, it would pretty much eliminate scratched up valve covers and be a great option for bikes that already have scratches on their valve covers. I love the idea of doing the engine oil coolers. The previous owner also had the front engine cover RhinoLined with the same finish and it looks great and balances out the RhinoLined rear parts. Doing the beak might look pretty cool, too. Seems like it would be the perfect option for ruggedizing a GS.
