    Clear coating of any kind over polished aluminium is a complete waste of time. However if customers insist, then I doubt very much anyone doing that sort of work commercially is going to refuse to do it?

    Powder coating applied over bare metal may well also fail after a while. Proper way to coat a frame is to blast clean, heat in oven to degas, then apply epoxy powder primer, and finally top finishing coat.

    A lot of people miss out the epoxy prime coat, and this can lead to problems on bike frames and parts.

    I understand your point of view, I guess I just look at it a different way. My perspective is that all coatings will eventually fail, or get so worn down that you will want to redo them anyways. Coatings serve 2 purposes, to temporarily protect the underlying material and also for aesthetics. In the case of coating polished aluminum, aesthetics don't play any role so we are purely looking at the functional aspect. Say you get 20 years out of a fully prepped and powder coated piece, maybe you will only get 5 years out of the clear powder coating over a polished surface. How long would you get out of bare polished aluminum before it has to be re-polished?

    I understand that polished pieces can be maintained and I do leave certain polished aluminum pieces bare if they are easy to remove and polish. A frame is not the easiest thing in the world to maintain the polishing on. Lots of tight corners, stuff in the way, ect, it will never look as good as the day you first polished it and will continue to go downhill unless you do a completely disassembly. Putting a coating on it(although it does degrade the polished look slightly) will maintain an overall better look for a longer period of time.

    Again, thats just my take on it.

    mudvaynedude122, I'm one of the converted. My baby is an E30 turbo doesn&#8217;t come out when its raining bla, bla, bla. She's polished, plated, painted and powder coated, so I really do get it, I just think it's an XR650, used maybe everyday why make life hard on your self. Use the most robust method of protecting the frame for the future.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:eek:ffice:eek:ffice" /><o:p></o:p>
    (Also please don't think I'm being dismissive about the bike as everybody buys either what they can afford or what they fall in love with, so each to there own)<o:p></o:p>
