There is no polishing involed with Chrome powdercoating.
Sandblast, powdercoat & then a clear powdercoat....done.

Be very wary of chrome powder coating . i had it on my fuel tank on the old piranha and it faded over time .
The guys where honest with me before i had it done and told me that they had previously done a bike frame and that it reacted very badly to cleaning solvents and polish . I cant say that mine got clear coat or not , but the rest of the frame did so i cant see why not .
make sure you ask the question :wink:
If it doesn't burn fossil fuels it aint a sport !!!

Buyer beware, chromed stressed parts break. The problem with actually chrome plating is you get hydrogen embrittlement

"Hydrogen embrittlement is a brittleness of metal and chrome layer structures, resulting from the occlusion of hydrogen into the base metal itself. The hydrogen absorption and the internal chrome bond creates a weakness and ductiility issue. Basically, the hydrogen is interfering with the metal's ductility, which in turn makes the chrome build-up weaker and greatly increases the chances of breaks or cracks in the chromed area.

It also is important to keep in mind that the hydrogen embrittlement becomes more of a threat as the amount of chrome applied increases. In a build-up - one in which you are applying layers of chrome - hydrogen becomes trapped between every layer of chrome applied, thus increasing the chances of hydrogen embrittlement. In a flash chrome situation - one in which a minimal amount of chrome is applied - the probability of this problem occurring becomes less likely because the hydrogen doesn't have as many chances to embed itself within the structure."

The construction / Aviation / Motorcycle / Automotive industries learned that mistake many years ago.

Actually that is not the original article, that is just another form of the article. Here is a copy of the "as printed" article.
Copies of that article have been making the rounds for years on numerous forums.

Whether it is the original source is not the problem. Passing someone elses work off as your own is pretty poor form in my opinion :wink: .
