Has anyone stripped and polished 4dx 3tj frame??... If so what best way to do it??

I'm. Sure they have :)
Go onto Frost website or ring them and see if they do something specific, they do polishing kits

Yes; that's them; the one right at the top.

Yup Frost

They stock everthing you thing you need a lot that you don't and quite a bit that you just want :)

I've done a few. It's hard to get the hard anodising off. Sand off anodising (wet n dry) then polish with buffing mops finishing with unstitched mop. Very time consuming.

The original finish is hardwearing and very easy to maintain, as in it requires no maintenance at all.

Once the anodising is removed a whole world of pain is, like the base alloy underneath, exposed.

The frame becomes a high maintenance item and if left to tarnish, very soon becomes stained and eventually, pitted.

Nah, a properly polished frame isn't hard to maintain at all. My Bimota has polished frame and swing arm, I go over it with autosol or use a mop on a drill once a year

I know; but he might actually take his out and ride it in all weathers .

I don't think I've had road salt on it very often but even then you can have a polished frame and the earth will, shockingly, still orbit the sun. It needs to be properly polished though, I think you need a sealing mop / polish before the top one.
