I finally tried hitting blend panels with 600 grit wet before color, and now I cant decide if its genius or a waste of time
Had a silver metallic bumper job two weeks ago that kept showing a halo on the blend. My supply guy in Fresno told me to knock the blend area down with 600 wet before laying color instead of my usual 800 dry. Car came out clean, no tiger stripes, took me maybe 15 extra minutes. Now Im wondering if I got lucky or if this is something you guys do all the time. Half of me thinks its a legit trick for stubborn metallics, the other half thinks im just adding a step I dont need on every job. Anyone running 600 wet on blends as a rule or only when the color fights back?

I remember reading on a forum years back that the old timers used to wet sand blend areas with 600 before color on problem colors, especially silvers and golds. Something about the finer scratches letting the metallic lay down more even so it does not flash or stripe. I tried it once on a gold Camry bumper and got the same result you did, clean blend with no halo. My take is it is worth doing on any metallic that tends to fight you, but on a plain white or black solid it is probably overkill. If you are only out 15 minutes and the job comes back clean, that seems like cheap insurance to me.
