Hereof, do I have to wet sand primer before painting?
Whether you're talking about paint, primer, bare metal or anything in between, your car's body can be smoothed by wet sanding. Wet sanding, also known as color sanding, adds shine to a finished paint job.
Secondly, are you supposed to sand after primer? Sanding after applying primer should help keep your surface as smooth and flat as possible, eliminating brush marks, or extra little globs. Also when painting, like others have pointed out, can raise little fibers from the drywall, going over the surface with a sheet of sandpaper can help get rid of those lose fibers.
Just so, how soon can you wet sand primer?
Allow more time at cooler temperatures. Dries to touch in 20-30 minutes and is fully dry in 1 hour. When dry, surface can be immediately recoated, top coated, or wet sanded. For best results, allow to Primer to dry for 1 hour before dry sanding.
Is wet sanding necessary?
First of all let me start by saying that wet sanding is definitely an advanced process for paint correction, and I only recommend it for those already skilled at paint correction with a rotary polisher. The most important detail here to remember though is that you always need to be cautious when sanding.
