Question: After Mercedes wheels painted gray gun metal power on 1998 ML320?
Will this look good or do I get to all the new rims. I'm going to color the window. Also how much does it cost to get powder coated gun metal job? Thanks
A: Powder coating costs about $ 30 - $ 40 per rim. It looks ok. Id personally buy only a couple on a new M-Series some bigger wheels and wider tires (easy, not ridiculous) would look nice.

Question: can we prepare a polymer with its density different from its standard density?
density of polypropylene is 0.9gm/cm3. if i want to prepare polypropylene with density 0.7gm/cm3 what factors should be considered
Answer: Yes you can prepare low density polypropylene. Forget crosslinking because that is a different polymer. Selecting isotactic or melting the polymer and freezing it real fast lowers the density to 0.85 gm/cc. You could try injecting modifiers but that may weaken its other properties. You could also select another polymer with a low density, and blend it with polypropylene. There are many choices, so good luck
