1. Stripe paint using pye paint remover or other brand oso can ( acidic ; becareful )
2. Get ready three sand paper ( 400, 1500, 2000 )
3. Undercoat / Primer coat  spray can chrome silver ( if needed )
4. Autosol or any brand available
5. After stripe off paint, use 400 lightly buff the dull metal color off... super gentle, objective just to peel enough the dull section away without leaving too deep groove lines... Do this under running water and will get a smoother effect
6. Repeat with 1500, but this one use harder force as to even out the surface.. also under running water
7. Repeat using 2000, also under running water... even out all the lines initially with pressure.. then lighter and lighter until smooth
8. rinse the casting off... wipe dry
9. rub autosol as per instruction on the tube...
10. wear glove on left hand if u use right hand to hold polishing cloth to buff off or vice versa
11. after the cream dried, buff off until it shines can see ur own face...
12. careful after buff area is shinnning like chrome, do not touch using bare hand.. else finger print will be imprinted and hard to wipe off once shining.. thus require u to repeat the process 11 again... do not try to use transparent lacquer spray to coat it.. will destroy the shine... i have tried that, end up redo again
