Ive had a bunch of Rovers all do this same oxidation deal on the hood. Thought I'd give out some of my tips to at least make it look better. Along with other scratches and scuffs on the truck. Not restoration quality but good enough to feel like you aren't driving a worn out turd wagon.
Here's what I started with: 2003 D2. Even though it's got low miles this good has been neglected. The roof has typical clear coat peeling but I'll get to that later.



These are the products I use. I have tried many different brands and products and I can say I really like Chemical Brothers. I use a 6" DA sander w a velcro attachment. I prefer foam pads over microfiber. But I do use both. I definitely don't like wool pads. Too abrasive.
The chemicals I use are a system of progessively finer and finer compounds. Then into a butter wax which I apply by hand. Starting w #32 Ultra Compound. This is the most aggressive step. Depending on how bad your paint is you can start with what grit you feel is appropriate. Mine was pretty bad so I started at the most aggressive.


In that shot I did a small area just to ready out the steps to see how it would come out.
1st step is to wash/dry it. Then I use a clay bar to pull out any stuck gunk. Then I wash/dry it again. I start with the compound in small sections. Sometimes you may have to do the areas more than once. As you cover the entire section the remaining compounds get easier and easier. The products will spread more as the paint gets more slick. When I go from compound to polish I switch foam pads to a lesser aggressive one. They are color coated.




​​​​​​
Here's the final results. It's not perfect but I think it's world's better.




I also restored the headlights too. Next up i will be doing the rest of the main body of the truck. Typically I start at 36 or 38. There's no need to use heavy compound unless it's really bad. Remember the smoother the paint the shinier it will be. Hope this helps you guys out w making your rides look better.

 

Looks great Shift nice work

 

Here are some updated shots of the rest of the exterior of the truck as it has progressed.
