Weather

most manufactuer's instructions say to only apply/use above 40F. I gotta say, 40 is cold. I tried it once, and it was a pain. The wax dried slow, as did the water from when i washed it before hand. But to answe your question, yeah, its probably ok to polish, seal, and wax the car when its 50. Read the bottles though, most say in the instructions what temps you can use them in.



Polishes however, shouldnt matter the temp. They may be thicker and harder to work in the cold, but they will get the job done.
 
I normally use 45 degrees as my cut off point. As long as it's that or above I'll wash and wax. haven't tried polishing at that temp yet so I'm not sure how it would work.
 
I good to about 40 degrees. It was cold here this morning at 9AM when I washed the Lexus today, around 44 degrees. And I went out in bare feet! Ouch!
 
~One manâ€â„¢s opinion / observations~



Temperature conditions:

These are the temperatures and conditions that are relative to the application of car care products; the most important is the actual surface temperature of the vehicle. The other things that will have a direct bearing on this is the humidity as this will effect the cross-linking (cure) time, excess humidity will also affect â€Ëœhowâ€â„¢ a wax or sealant dries (i.e. it may cause hazing or clouding of the surface)



The other climate related condition that should be avoided when applying car care products is direct sunlight, as this will dramatically increase the surface temperature compared to ambient temperatures causing the product to dry prematurely and may render it ineffective.



1. Surface Temperature (Actual surface temperature of the vehicle)- 60 â€â€œ 80oF products will work well within a much broader temperature range, (50° to 90° F) but the best results will be achieved in the 60° to 80° F range surrounding air temp (ambient or room) must be 55oF + to ensure the minimum vehicle surface temperature of 50oF(recommended as a minimum by most manufacturers)

2. Ambient Temperature (Outside air temperature)

3. Relative Humidity (Moisture content of the air)- RH 50% +/-10%

4. Inside Air Temperature (Room Temperature) 70 â€â€œ 75oF +/- 10oF and 50% relative humidity +/- 10%

5. Air movement or windy conditions will increase the evaporation rate but potentially make some products more difficult work with, especially sprayed products. Perversely this can lessen wax / sealant drying time.



In summary, the ideal conditions for the application of car care products; cool and dry, away from direct sunlight, a surface temperature between 60° and 80° F, 50% RH or lower humidity, and a light air movement.
