45-48 here in mass this weekend, i am going to wash wife`s jeep and my truck real well and apply a sealant LSP. Power wash out side with foam cannon to remove dirt and as much road film as I can then in side with heat on for rinseless wash. I may even full wash out side with my boars hair tri headed brush, yes i know a BRUSH!
Dude, I was also so excited, even in spite of the following forecast for 2 days of rain (which was true unfortunately). Still, I enjoyed 2 nice cigars and washed both cars. All was good for a while.
I used to wash religiously, regardless of weather. As long as I knew the sun would be out long enough to dry the pad. No more.
I waited for a wash today after work, as the rains will have cleaned up some of that latent salt/dust that is in all the nooks and crannies of the blacktop.
