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
