Hi Kick, 800 has too much bite if used dry and will clog up the paper really quick without something to keep it lubricated.
Pour some water in a bucket and add a couple of drops of dish washing detergent then wrap the grit paper around a cork sanding block and dunk it in the water to lube things up. Then run a couple of light passes over area to be sanded, rinse the sanding block (with paper still wrapped around) in the water to dissolve waste and keep lubricated, then go again, and again, and again. Also handy to have a micro fibre cloth to wipe away the excess water on the guitar body as you don't want any of the sludge drying on the surface.
Using TO as the lube is quite messy and can lead to runs very quickly. I am actually using diluted TO with around 50mm x 50mm squares of 2000 at the moment to apply final top coats on the Swampy Tele and hope to put a couple more on tomorrow then get stuck in with a proper water based wet & dry session on Tuesday to bring it home. For the final polishing it must be done with water.
Cheers, Waz
