[quoted from the site:]

Gray splotchy areas that won't polish out. 
One common problem with polished aircraft is gray areas that 
are visible in the sunlight that seem to be impossible to remove 
with any amount of polishing. No one seems to know what exactly 
causes the splotchy gray but until now nothing would remove it 
except acid etching. But we've had good luck getting rid of the 
gray with Nuvite G-6. The F-7 medium coarse may also remove the 
gray; we just haven't tried it.

[end quote there was a mention of the brown effect but I cannot find it now.]

fwiw
