When I refurbed the legs on my RD350LC I thought about clearcoat but I think it's a short term look as eventually it deteriorates....one of the lads on the RDLCCrazy forum recommended ACF-50 https://www.learchem.com/products/acf-50.html which is used to prevent corrosion on aircraft. Just a light spray and a wipe down every now and again will keep them fork legs looking good if you decide to get rid of the clearcoat. It seems counterintuitive to me as surely it will attract brakepad dust and turn it into grime....but you just have to keep on it... aircraft owners swear by it and it's not like the old days where we rode them everyday to work, or to college or best of all, to the pub certain that two pints was definitely 'under the limit'.

Re-anodising is possibly the hardest wearing option, but the problem is brake pad friction material is extremely corrosive, and when paint, clear coat, or anodising is chipped, the brake dust will immediately start attacking the alloy.

There's no perfect solution, but I've also had very good results with ACF-50. ACF-50 reacts at a molecular level with alloy oxidisation, neutralising it, and an application definitely lasts longer than anything else I've tried. I don't find it attracts dirt as much as something like WD40 or silicone spray, and you can apply it a lot "drier", if that makes sense?!

Performance Engineering treats all the vapour blasted parts (crankcases/head/barrels etc.) with a light coat of ACF-50. Or at least we did when I was there.
