I used this one:
mykeln/teslaprep. But to be honest I'm not that anal about such things and I was only really concerned about the paint since everything else can be sorted after/under warranty (and it's unlikely you'll spot EVERYTHING even if you spend an hour with a fine comb before driving off).
I noticed the tiniest amount of condensation in the passenger side rear light earlier when I was sorting the rear numberplate out. But it has been sat somewhere since getting off the boat for ~3 weeks under 2 storms so I'll just keep an eye on it now it's in use and being heated etc.
Otherwise no, no issues at all that I can see.
