have you tried the Lucas Slick Mist interior detailer yet - $7 at Walmart and it works - - before you go out and try another specialized high $$ product why not give it a try
F11 will still attract dirt to the tub....I won’t randomly spray it under my hood and inside the fenders.... $$$$$$ issue..
Does your tub get dusty with the slick mist?
The product I’m talking about is cheap as pledge...
So far it doesn’t matter what I’ve used the tub gets covered with dust....I’m still leaning to it being a static problem...too..
