Sanding before clearcoat

[bulldogcountry1]

Today I sprayed SS gloss black PPG DCC, and the finish overall looks good, but there are a couple of areas that have a slight orange peel and a few dust particles. I am going to lay down a couple coats of compatible clear for extra protection and shine. What would be best to achieve the best finish?

Should I wet sand the top coat before I put the clear on or wait until after lay the clear? If so, what grit can I use? If I don't sand the top coat, will the clear mask minor surface irregularities after I sand it and buff it smooth?





Thanks.

You will have to sand the dcc in order for anything to stick.IF (I) were putting 2 coats of clear on top of fresh paint,i would use my airvantage with p600 grit dry making sure not to cut through edges.Then scuff the edges with a grey scuff pad,wash..then reclear it.

If you're going to wet sand it by hand use anything between 800 and 1200 to scuff the single stage paint first.
