Most of the 'weight' (reletive to gravity), in paint is only in the 'stuff' that lets the paint spread over a surface. Most of this 'stuff' gets sublimed into the air (the smell that makes you high). When you paint something with a can let's say 500grams, only a small portion of that actually gets dryed to the surface. So it would be quite reasonable to spray your skiis with 3 cans of paint, the 'weight' added would be negligable. and second.
Chrome is EVIL!!!! Chrome is one of the softest alloys around, and the polymers coating your ski is even softer. If chrome is added as a shell to a surface and a 'knick' ever gets put in it, it will slowly send surface and point defects through the other material (throught your skis), these point defects on a short term actually strenthen your ski, but in the long term the polymers will become brittle, the ski will snap like one of those clear bic pens.
