You are not being over cautious, believe me, I wait at least 2-3 days before using Solvaset. A while back I decaled about 24 hours later and the area around the decal clouded up really bad and got chalky. I even applied more Future over it but it didn't help.
I find that it sprays better and smoother mixing about 50/50 Windex and Future.
