I don't particularly like the amount of orange peel in places, even though I sprayed the last two coats fairly wet. Should I try to wet sand the base-coat before spraying on the clear-coats, or wait after the clear-coat is applied? The paint is Omni PPG.
Thanks, Don. | | | | | Joined: Feb 2004 Posts: 29,747 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,747 | Back when I was doing a lot of base/clear painting, the procedure was to spray the clear over the base without sanding if there was less than a 4-hour time span between applying the base and following up with the clear. After 4 hours, it was necessary to scuff-sand the base coat. If you've got orange peel, I'd suggest wet-sanding the orange peel areas, and scuff-sanding the whole thing. Do a very good wipedown with a tack rag to remove any sanding dust.

Then go back and lay down one more even wet coat of clear.
