I use duplicolor can spray my door trim panel with base coat yesterday (24hrs ago), and I plan to spray on the clear coat today, but I know I probably should not wait that long time to apply the clear coat after research yesterday night.

So what should I do before I spray the clear coat? Scuff the base coat a little and apply a light base coat again? or I am still fine to spray a clear coat to it directly?

(my car sits in a garage with no window and nobody accessed yesterday except me after the paint)

Thank you so much for any suggestion!

You need to find the mfg's recoat time for that product.
A lot of them have a 24 hr or longer recoat time.
When in doubt, it's always a safe bet to scuff and rebase before clear.
I wouldn't sand it with anything more coarse than 800 grit.

Hi, thanks for your reply, I did not get any reply before I worked on that issue at that time, so I scuff the base coat with an 800 scuffing pad and adding on a light base coat then do the clear coat. The result is acceptable. But thanks for your reply!
