  • I'm looking get my Colnago in Saronni lookin new.

    I was told that polishing could damage the clear coat of the original paintwork and it's dangerous putting chemicals to paint. (Paint is in good condition as is)

    I purchased Meguiars Deep Cyrstal Cleaner and am unsure if I should use.

    advice would help. Thanks

  • That product actually describes itself as 'non-abrasive' so perhaps test it on a less critical area, under the BB shell for example.
    I doubt there will be any chemicals in a Meguiar's polish that will react badly with your paint.

    That's precisely how most proper car polish works. It finely scratches through dull flattened clearcoat to reveal a pristine layer beneath. Different grades of polish will have more or less aggressive 'cutting' power. It's very easy to apply too much pressure or use too coarse a polish and burn through the clearcoat to the paint, particularly on non-flat surfaces such as bicycle frame tubes.
