Absolutely agree with Rick...I use the corner "area" (maybe 3" x 4") of a small terry rag and just spray a few times.
Keep in mind I'm doing roof rack parts, not the cladding. You can get ALOT of mileage out of that damp section of rag. I use a rough terry towel cuz I'm using the rag to clean and rub off lots and LOTS of oxidation type crude off the plastic parts, so I need the rough texture.
After the cladding, use the damp area on your interior panels, dash, console, back seat, etc....
And also agree with Rick- you can use the rag area even after it's basically "black". I even continue to use the same area on the rag the next day after spritzing it with the 303 again.![]()
