Still at it girl? Good for you. Here is a link
to a slideshow of a tank I tried polishing
without using a buffer. There maybe
something in it you can use. I get this
sand paper at Home Depot. It’s the best I
have found but it only goes down to 400.
It has like a plastic film on the backside to
keep water out of the paper when wet
sanding. Using some water in a spray bottle
can keep the sand paper from clogging up.
Polished can be from shiny to an un-distorted
mirror reflection. It’s all hard, nasty, boring,
work. Have Fun!!!!
