Personal preference. At your own risk. Just spoke to my Paint Pro who installs PPF daily and he said that new paint definitely outgasses and if the PPF is installed too early the outgassing will deteriorate the adhesive on the PPF. You won't really notice a problem until you take it off and the paint comes off with the PPF. For the most part, new vehicles take at least 30 days to get to you, so generally, it is not a problem, however as grandmother always said. "It is better to be safe than sorry." What to do while waiting? Stay away from car washes and dump trucks.
The problem with the new paint is that shipping by rail means that fresh paint is subjected to railroad wheel and rail dust. This fine rail/wheel dust is created by the friction of the wheels rolling on the rail, creating hot aerosol iron filings. These filings were hot enough to “melt” into the clear coat. This is a bad thing, especially if you’re painting millions of cars and trucks with an outlook of having to repaint those cars and trucks under warranty ( for free). Some manufacturer's now put cloth car covers on their vehicles (like Lexus). Some plastic coat, but the plastic coat is not PPF.
