    If you have a healthy polisher you can get away with stopping at 1000grit on easier to reach spots. I have this http://www.harborfreight.com/garage-...fer-40668.html And with some good compound it'll take paper marks out pretty quick.
    I wouldn't shoot for mirror finish if you plan on getting it dirty, even wiping dust off the frame will dull the finish.

    Hey, so I'm a complete newb to this field of information and have some questions that highly reflect my knowledge of the matter. So, I pulled out an old Specialized Hardrock Sport, and I mean an old one. It's a tad smaller than I'd like, but this bike is going to Burning Man and so long as it is functional, I'll take it. It will remain rather squalid in comparison to much of the metal work there, but I'd like to touch it up all the same. It's a Chromoly frame and I have heard it is possible to polish it nicely. Anyone have a guide handy?

    10-4 on that. I stopped at 1200 grit wet, then automotive rubbing compound, then polishing compound, then, of course, Mothers.

    ehigh - I have no experience with steel in this context. I ended up painting the rigid chrom/moly steel fork with Duplicolor chrome at 800 grit. Work OK but will try something different in a couple of months. Did not clear coat the aluminum (and have no intention to do so) but would need to do something like that with steel.

    Yeah I had read mention of it on a different forum, but there were not any definitive answers.

    If it's going to Burning Man, you might consider some neon spray paint & flower stickers. Maybe for the bike too. Then figure out the best method of polishing/coating afterward. Also, be sure to take a gross of prophylactics with you! What a party that event is...

    I'm a gun guy, so I'm thinking of blueing the fork. That would look good in contrast to a polished frame. Probably not practical for a complete frame.

    No doubt there are a number of ways to get to the final product. I found that knowing when enough, was enough, was my biggest problem. 2000 grit is serious dedication. And some of it depends on if you have a 6061 or 7075 alloy frame, as far as brush marks & crash ding penetrations are concerned. I like the brushed look but wonder if those events make that inevitability more visible?

    Do you mind a brush marked 4X4, or do you want a perpetually polished Porsche? We all have different expectations, I think, and need to proceed based on those considerations. Whatever the choice, RAW bike frames are unique & a personalized statement.of dedication

    It may end up getting some paint on it once it is there, but I think I can get it shiny. I found this old thread
    BMXmuseum.com Forums / POLISHED, NOT PLATED!

    Sounds like a lot of work, and I might not get it that clean looking. I still think I'll give it a shot though.

    And I definitely plan on being prepared, regardless of how dazed I may end up becoming.

    Great link! Amazing photos & saw the process as I scrolled down. Again, that is dedication. BTW - At Burning Man, if you have 2.4" tires of wider, mount them, & run at 35psi or so. Hardpack turns to silt dirt/sand in a few feet. Well, it did when I was there - '92, 96, '02, etc

    Hi Craigstr,

    I have an EG too and have been contemplating converting her to raw aluminium (with clear coat). While there are many bit and pieces of instructions here, i wonder if you can help by advsiing me whether the process that I have put together below is correct (for stripping my frame down to bare aluminium):

    Note: My front triangle is current powdercoat, while my rear trianle is anodized...

    1) Strip bike bare of all parts, inclu bearings, shox etc..

    2) Front triangle: spray on paint remover and leave it on for at least 15min to remove paint. (1) immerse (2) scrub (3) wash off (4) repeat (1)-(3) until all paints are off

    3) Rear triangle: immerse in oven cleaner for at least 15min to remove paint. (1) immerse (2) scrub (3) wash off (4) repeat (1)-(3) until all paints are off

    4) For both triangle: (1) wipe dry (2) sand down with normal sand paper to create a “brushed” look (3) Clean and wipe dry

    5) Clear coat: (1) spray a clear coat over the frame (2) thorough dry the coat (3) repeat 8-9 coats

    6) Final touch: (1) wet sand with 1500 grid sand paper (2) wet sand with 2000 grid sand paper

    7) Viola, nice new RAW frame with clear coat.

    Oven cleaner will eat Al. I would wet sand the ano off. Front triangle will have a nice bead blasted finish under the powder. I would leave it that way, the clear will stick to that better then anything. Clean the frame at least 6 times before clearing.

    Mine was painted, Im not sure if powdercoat will come off as easy as paint. If you have trouble you might have a painter or powdercoater chemically strip it? Let us know how it
    goes.

    Honestly, if it were me, I wouldn't spend the money and time to clear coat Al. Al doesn't corrode like steel, and bare Al can be easily cleaned up to look like new.

    I think there is clear powder coat. I would consider that, done by a professional, if it was suitable for a bike frame.

    nope long time buddy!


    I just don't know if I want to ruin a perfectly good finish to make it look like a mirror. My reasoning is this..
    1. I only have 1 season on it, and it was a short season since Ohio has been so wet this past year
    2. A mirror/polished finish would not be ideal for me. I do not ride with pants, so looking down at the frame while riding I would see the bottom of my beanbag in the reflection

    I just don't know about that yet..maybe after this season

    So, after this season, it will be ok to look down and see the bottom of your beanbag?

    No, I'm never going to be able to get around that, but if I wait another season it will help me justify it for reason 1. I do like the stock paintjob...and once it's mirrored I can't go back
