With the grain of sand blasting I begin with dry 240 then 400 dry again and go with 600, 800,... wet. With this work no need to go to bodybuilding room...Can´t really give any tips regarding polishishing besides the obvious: Start with 800 and work your way up to finer grit. I usually stop at 1500 and change to 3M pads, then your choice of polishing compound. Maybe use a certain multitool (can´t think of the name right now) for the welds? Hope your elbows are well greased ...
. For sure, the powder paint of the front triangle will be very dry before I finish the rear...
