Re: [APD] Clear for Life Aquarium Problem

That's the key. Each grit must be worked long and hard
enough to remove the scratches of the previous grit --
literally, to scratch away the prior scratches. Since each
grit is smaller than the previous, it takes a bit of work
to remove the prior scratches. And for this reason, it
actually takes longer to do the job is you skip too far
going from one grit to another. The closer in grit size a
sanding/polishing material is to the previous sanding, the
quickler it can remove the prior scratches. Jump too far
ahead in grit size and you'll spend all day and not seem to
be getting anywhere.

Once you progressively get down to a fine enough grit, the
eye cannot detect the scratches anymore. So basically,
you're trying to turn big scratches into itty bitty ones.

One need not strive for true perfection, imperceptable
imperfections, while unavoidable, are acceptable ;-)
