Randomly came across this deal on Repco. It's part of their Catalogue Sale and ends on July 23rd.
When it comes to car wash, I prefer to do it myself and the main issue I've always had is that I can't get a good foam all around my car. Having a good foam cannon is key, but these are typically expensive. This one seems to have very good reviews online.
If you have a Karcher pressure washer, you can get this adapter kit that will work with the foam cannon:

It would be nice if I could just get everything from the Chemical Guys and if they could offer a price match or even price beat.
I would highly recommend mjjc. You can get the compatible adapter for your washer. I have Karcher one. Using it for some time now and it's one of the best. I wash my cars at home. Foam cannon and later 2 bucket method to get it nicely clean.
