The project pictured is straight out of the paint booth and required no buffing. It is necessary to use all the additives to attain the enhanced gloss. (Pass on the FEE)
It sprays like a quality clear and after a quick drop coat it goes on wet on wet...
If your going to buff it be sure and nib and cut it with 1000 after 24 hours but not later than 72 hours.. Then let it gas out another 12 hours then re-sand with 2000 and buff as usual.
Have a NEW respirator for this stuff and a clean paint room.
It would be well worth painting a practice panel first...
you can do it!
