Definitely agree, we need more info on what exactly you want to clean up. Rust, aluminum oxidation, paint/clearcoat peeling.....
Then, 'clean-up' means diff. things to diff. people. Lots of people are anal, lots of others want 'preservation' because it's only original once. Other's don't care and just want it to look good.
I will say that I get a lot of product from Eastwood company. Lots of specialty paints for different metal finishes, abrasives, rust preventatives, body tools, garage stuff.
Now that I think of it, Clean-up, is sort of not related to patina at all. Patina is leaving it as Nature made it.
Removing paint oxidation to bring back more paint color is something you may be after. Or not. Meguiars used to have a good product for that. "Color Back" I think they called it.
Proper compound, Polish, wax. DIY: meguiars ultimate compound, Polish, then wax of your choice. I suggest using an orange foam pad on a DA polisher like the porter cable 7424xp with the compound, then a less aggressive pad with the polish. Yes, you can do it by hand... But it is lot of work, and won't look anything close to what the machine can do.
Sorry for the delay guys.
Yes the car's paint is original and rather faded. i Was hoping to bring it back to its glory days as much as i can .
Give the old girl her shine again
The original lacquer paint is very different from the clear coat used now. There is no top 'clear' coat. If you are not proficient with the 'machines', you may damage the paint. Hand work is hard but safer.
It's basically a multi-step process.
1. WASH and dry.
2. To remove petroleum based 'spots' (tar etc), nothing beats a gas soaked rag. Follow up with a immediate water soaking.
3. Rubbing compound will remove the top part of the finish. Use thin coats and do sections (hood, fender, door, etc) of the car at a time. Only 'buff' as hard as necessary to remove the 'haze'. Assess condition and repeat (again THIN coats, light buffing). You may be able to tell (I can) if the paint is too far gone as you progress. If it is not...
4.Polish (less abrasive than compound) similar to the compound. The goal is to remove ONLY what has to come off. One application should be sufficient.
5. Wax similar to the polish. Thin coats! More thin coats are better than one thick.
6. KEEP the car clean and waxed. Stains and surface imperfections are a lot easier to 'fix' if they are in the 'wax'.
