Hi there. I have been trying to locate some protective application to preserve the aluminium parts of my bikes after they have either been polished or wire wheeled to death. I have researched thru the web & have only unearthed a few solutions which don't seem to be worth it. The one I thought would be the best was a product by POR15 called 'Glisten'. Unfortunately I haven't found any reviews of it that would corroborate its benefit. Most of the others were either wax polishes that needed to be reapplied or plain fish oil. I came across this product CRC Lanocoat that is a mixture of lanolin & fish oil. I thought it may be interesting having an ongoing experiment to see how it lasts. I live approx 300m away from the sea so everything around here corrodes. that is the main reaso I don't bother maintaining a polished anything ( that & laziness I guess) So I got a old piece of flat bar, gave it a good buffing with the wire wheel & sprayed a portion with the Lanocote. the rest I left as is. This was done approx the start of Oct 2013. I left it outside & here is the results from today. Quite a difference so far. I think alloy will age differently so will spray some parts of the bike & record the changes too.
