72 duster Build progress

this is from a similar primer as what i have and i believe its all the same specs.

APPLICATION
Apply 2K Urethane Primer Surfacer in two medium wet coats,
allowing 15 minutes flash time between each coat. Additional
coats may be applied for more build.
DRY TIMES / RECOAT
FLASH TIME: Allow 15 minutes
DUST FREE: Allow 10-15 minutes
WET SAND: Allow 2-3 hours
DRY SAND: Allow 3-4 hours
CURE: After 18-24 hours

Once entire surface area has been leveled, primer may be topcoated for up to 18 hours without any additional prep. After
18-hour recoat window has passed, surface of primer must be
abraded prior to topcoat application.

Ill have to check mine and see if it is the same. not a problem if it is.
