Waxoyl Question

[Joseph Cianciotti <jmc987@earthlink.net>]

I've procrastinated long enough and now need to Waxoyl my B's sills 
before the "el Nino" really hits. Should I be concerned about the 
temperature and humidity when I do the job?  My car is outside (no 
garage) and I'm afraid that if I put warm Waxoyl into a cool sill on a 
damp day, the moisture in the air inside the sill will condense and 
interfere with the rustproofing process.  What are the ideal conditions?  
Thank you in advance for your responses.
