F350Lawman:
I wax my Ford 350 with paste wax about twice a year but I use hot spray wax on everything else including the tractors. Because I wash so many different tractors and implements, 3 years ago I went out and bought an Alladin 3500 psi Diesel fired pressure washer. I bought an industrial model from a local outfit that supplies the auto makers. They also sell chemicals. First I was the units down with a product called Fleetwash. Then I rinse and then I apply the hot spray wax. After I am done, I towel off the glass and the paint and the tractors look like new. The spray wax is a silocone base so it tends to make the finish slippery. Makes the bucket very easy to clean. I think if my wife caught me waxing the inside of the bucket, she would make an appointment with the doctor for me!!
I had a couple of those pressure washers that Northern sells and you get at Lowes, but when they kack out, you can't get them fixed. The one I have now cost over 5K, but in three years all I have done is change the oil and clean the inlet strainer. If I ever need service, the company I bought it from will pick it up (it's heavy) and give me a loaner while it's being repaired.
