This link explains the curing process in basic detail, and how it depends on several factors: https://www.feynlab.com/how-long-doe...4sZrIlNTkUDWzx

I've followed your link and read the materials on the Feynlab web site. I did not find any claims that all ceramic coatings require minimum of 2-3 weeks cure time before exposure to the elements. If anything, they follow the same claims in the above video by Yvan Lacroix (co-founder of DIYDetail) that ceramic coating cure follows two stages:
1). Initial cure when exterior surface hardens and car becomes safe to drive. DIY and other vendors say that takes 1-4 hours. Your vendor (Feynlab) claims their product takes 24-48 hours.
2). Full cure with chemical cross linking between coating and paint. Feynlab claims this take "several days to a few weeks". Other coatings disclose 6-24 cure times.

Finally, the punchline message from Feynlab site is very apropos:
"Follow the manufacturer’s recommended curing times and application instructions."

I totally agree with the above, and nothing on Feynlab's web site would make me want to go against the earlier cited cure times from DIY, Adams, Gyeon and McKeys (6-24 hours before road ready).

HTH,
