visited a paint store recently and liked their selection of sandpaper
and alothough i have not calculated the price i got some nice sturdy
sandpaper that has performed well and found some other products that
i had not seen before

plus they know the products and they know what works and what does
not

eg
tsp prep is not always a good idea and i have not needed it but
always thought that was a good way to prep a wall for primer

the pace is quite fast although i am not sure how advanced sandpaper
is now some of it seems to have regressed into the planned obsolence
model


getting hard to keep up with the state of the art in so many things now
