I carefully peeled off all stickers (to reapply later), then used Varsol to remove the sticker residue. With all residue removed, i cleaned the parts in the bathtub with a bar of Irish Spring. I then rinsed thoroughly with cold water,used a fresh towel to dry, then let sit for the remainder of the water to evaporate. This worked great, no fish eyes or distortion to the finish.
Several thin coats of Fusion were applied. No primer. I sprayed always with the same pattern, no crossing perpendicularly. I left the parts to dry over night before assembly. I then sprayed the back of all removed stickers with spray adhesive, and re-appied them (on rear of unit) with tweezers.
