Hisunil did lacquering on his Comet many times. AFAIK, he is the best person to check on this topic.

Thanks a lot Rossiter, you've provided a right direction to me. I don't know how to Thank you more.

I've to use Dupont paint & apply lacquer on it. I was able to get more info on Lacquer from - Lacquer - Wikipedia, the free encyclopedia. As of now it looks like Lacquer technique is being replaced by what is known as clear coat (actually Polyurethaneor PU); But need to find out who does Lacquer.

I posted to say a word of Thank as I got the idea; I'll learn on this more & find out people who can carry out this.

^^^ hmmm, ok, so is there a limit on which all metals can be chromed? I mean, what about alloys? I hope not, right? Yes, the hub is near to perfection, I mean, do damage in anyway, not even a wrench has falled on it.

Any idea like how many mm will be the grinding done?

The extent of metal removal by grinding will not be measured in mm but in fractions of mm. Remember, it's only to remove surface defects such as pits caused by corrosion.

Aluminium can be chromium plated but as someone else posted, it will first need a plating of copper. Chromium plating is a better option in the long term over buffing since it gives a better and more durable finish.

Sir, then what about alloys? I'm not sure what kind of material is my front hub, but I like to get that plated too; I'm assuming it should be alloy, in that case, should I go for plating it with copper & then chrome it? I think it was JD who told that it should be copper plated first.

For iron, I think direct chroming should work right? Also do you have any advice/suggestion for number of times (pls forgive my ignorance on this topic) it should be chromed for longer life so that the chrome doesn't peel off?

Alloys are aluminium alloy as well so the procedure will be the same.

For steel and iron, the part must first be plated with nickel and then with chrome.

Don't worry about the technical details. If you are interested in having parts chromium plated, just find a reliable workshop who does quality work. They will tell what can and cannot be done and how exactly it will be done.

^^^ That is the whole problem

My experience has taught me that unless I know some basics, people are ready everywhere to take me for a ride; I've experienced this at different point of time in different forms of plumber, electrician, carpenters, mechanics & what not?. My strong belief is learn about the work, ask the person who's gonna carry out the work, how he intends to do & compare that with the knowledge I gain; if it matches, then he's honest; then compare the work he promised & the outcome, they should match 99%, if not I'm one of the victim; I learned this hard way in my life since the age of 13.

Anyway, thanks a lot for the valuable pointers, I'll google for more info on this & keep them posted here

If you are interested in learning about electroplating, I suggest you search on the internet for sites with good information. You could even find sites with DIY information that could be comprehensive.

As for the electroplaters, I suggest you ask around (mechanics, shops, etc.) for their recommendations and try to see the quality of work that they do. Try to judge the quality of relatively old parts too.

Btw, if you are looking for a mirror finish, then preparation is the key. Ensure that the parts to be plated are buffed to a fine finish (smooth, not mirror). Electroplating cannot give you a mirror finish if the parts are rough to begin with since the thickness of plating is only a few microns.
