2k primer sand before second application

[MKH]

Hi, I applied SPI 2k primer and have finished the first blocking. This was done 3 days ago. I am ready to spray the 2nd coat of 2k. Does the 2k need re-sanding? Thanks.

As long as all of it was sanded during blocking, no more sanding needed.
Be sure to clean it very well and wipe with WG remover, then paint away.

After sitting 3 days, I would go over it with a maroon scotchbrite before cleaning and respraying. Always good practice to rescuff after more than 24hrs.
