This is my first convertible car.

My first 370

Two buckets
Pressure washer
Pressure wash Tires and Wheels first - one at a time. Blow off excess water, wipe it dry.
Cover up Wheels and Tires using very large Hefty's. I do the Tires and Wheels first because the car dries out too fast and all four take time. I get these out of the way first.
Pressure wash the car next.
Let the water rest for a couple of minutes and then wash again.
Apply my soap - Citrus wash and gloss. Use a bucket full of clean water to rinse off the applicator when I soap the car.
Let it rest for a few minutes and pressure wash the suds off.
Blow off excess water off door handles, gas tank cover, mirrors, fenders, lamps, b pillars, etc.
Dry without wiping the MF towels across the panels to minimize/avoid swirls. Lay down 4 25x36 MF towels -- dab dry. I rarely wipe off to dry. For the sides, I lay a large towel across the panel and dab dry.
As a supplement, I use CG Glossworkz.
