The run was about two inches long.
He stuck the tip in the beginning part and laid the brush down in the run and than pulled off.
Had to do it a second time on a 1/2 inch left over that brush was not long enough to reach.
Must re-wet brush each time.
I think your right about the reducer.
When I tape a run, I hit it again with another coat of clear but did not have too on this run.
Clear just looks a little rough sprayed there and they can hit it with 2000 today along with speck of dirt in center of deck lid and be done with it.
If I had spray a coat of clear over the run spot I don't think you would have needed to buff it but rest of car was so clean, I did not want to pull trigger and cause further problems because the deal was any screw ups on my part they would fix and buff. So tried to do it so they would not have to buff.
I just hate the idea of someone buffing my paint work.
