when using a hose spray nozzle this thing

you should only be using it on your soft top or in the wheel wells.
Don't use the spray nozzle on your paint.
Unscrew it from the hose and use the low pressure stream to rinse the car before washing. Wash the car (a good time to clay the paint) and when you are ready to rinse the soap off lower the water pressure so that the water's movement pushes most of the soapy and water off the paint. Like pouring a bottle of soda over a flat table, except your car isn't flat so the water will just run off the sides.
You might have to experiment with water pressures. After some practice you can clear off 95% of the water still on the car so your are only left with a few beads here and there.
Take the waffle weave and press on the water that is left. Don't wipe left to right.
That causes scratching. This using the flood rinsing method you only touch the paint very little to dry it.
After 'drying' this way you can spray each panel with a spray wax or spray gloss. Make sure the panel is very wet and so is the towel. Always use speed when buffing the paint with a towel and never use pressure.
Make sure to have at least one of these in your two buckets. They will save your paint allot of scratching.
