Re: cloudy sections
Alright, I have been working with polishing aluminum for a couple of years now, and I too have had the problem of getting rid of haze on large surfaced area parts, I have been able to obtain a very high gloss shine on small areas with a little work, but have always had the haze on the large areas. By reading most of the cases in this forum I pieced together teh information and have conducted a little experiment.
Hypothesis: The buffing compounds cannot do their job at low temperatures, they have to be liquified to perform their job properly.
I used one solid piece of aluminum as my control. I first wetsanded the piece of metal all the way to 600 grit. I then heated the metal by means of a propane torch and got it to a scalding temp. Then I continued to use the brown compound to polish the metal, no haze, then I worked up to white compound, no haze and a brilliant perfect finish. It appears that you can remove all of the compound when it stays in a liquid form. When I didn\'t heat the item I still had that pesky haze. I hope this helps all of you, try it and tell me what you think.
