Like Anthony, I used to live / work next door to the distributor (also dist. for Chris King, Thomson, Crank Bros, etc.) so I had a couple of cans kickin' around for the last couple years and it's served me well for a lot of different things. I sprayed out the inside of my winter frame with Boeshield and it's been good - that said, the frame is alu. anyway so it may not be quite as much of a concern anyway...
