POLISHED ALUMINUM CLEARCOAT SECRET+++
I am inquiring about polished aluminum, specifically the polished engine case pieces of 1970s motorcycles. I like to fix up these bikes as a hobby. My problem is identifying the clearcoat applied to these polished aluminum pieces. The clearcoat is so unobtrusive that a lot of enthusiasts do not realize it is there. In some cases the original Japanese factory applied clearcoat has turned to a yellowish color. Commercially available "Aluminum Clearcoat" products have proven unsatisfactory. What is the secret to coating polished aluminum with an extremely clear, long lasting protective application?
Many thanks,Michael Waugh

I am trying to find the best way to keep the aluminum parts on my motorcycle their mirror finish a long time and make them EASY to clean. I have tried many different things and I'm now ready to do whatever it takes to make them look show quality but very easy to maintain. I have heard of people using UV resistant clear coats. Any recommendations?Joe Mergl

Hello Joe; hello Michael.
Remember that there are countless grades of aluminum, and some are good for clearcoating while others aren't. If it was originally clearcoated or clear anodized, it's probably a good alloy for brightness, but if you stripped paint off of it, it's probably an alloy that wasn't intended to retain brightness.
It isn't easy picking a clearcoat either. If one coating was manifestly superior to the others in broad ways over a broad spectrum of conditions, the other 999 would have been off the market in short order :-)
Bright dipping plus anodizing isn't for the do-it-yourselfer, but it may be what was done on those bikes originally, and is available from plating/anodizing shops. Good luck.

POR-15 Glisten, amazing stuff.|
you can buy it online too, it's pricey but worth it. Clear powder coating can be good too, but its can be too thick of a coating sometimes. R Malm

The POR-15 Glisten PC has worked VERY well for my polished and brushed aluminum pieces. Is is very durable.

I've been researching this for a while. I've tried the Glisten PC --^, and yes it does add a haze. It's also prone to runs.

I used a product called
Everbrite on my polished aluminum valve covers, applies easily, no runs, & has held up very well. I have no affiliation w/them, just great results.
