i have a 65 galaxie that someone painted pearl white a few years ago. the car sat outside for about 5 years. i have wet sanded the paint with 2000grit paper and buffed the car, but there is a weird haze over the entire car. in some places it is shiny but others its dull. the car is very smooth feeling from the wet sanding but i just cant get it to shine like it should. i have tried many products like the Mequiars 3 step with the cleaner, polisher, and wax. and they all helped but it wont go away. i am considering a clay bar, would that help with the weird haze?
