How to remove stains and embedded dirt out of paint
Paint Staining
Sometimes you'll hear the word stain or staining when talking about the condition of the paint. Another term would be embedded dirt.
The 1963 Galaxy has a modern basecoat/clearcoat finish. After using the Nanoskin Autoscrub Pad over all the horizontal surfaces I removed any and all above surface contaminants. In the video I repeated the baggie test multiple times to check and ensure all the contaminants were removed and in fact they were.
So where does the dirt come from? It's embedded in the microscopic surface imperfections of the paint. Here's a brand new white foam polishing pad next to the single pad I used to machine apply the Optimum GPS.
Purpose and Goal = Restore Clarity & Full Richness of Color
So even if your car's paint looks clean and clear, if the car is a daily driver, parked outside at least for some portion of the day, chances are very good that over time the paint will become stained with embedded dirt and this is why periodically you want to use a cleaner/wax also called an AIO or All-In-One product. A pre-wax cleaner, also called a paint cleaner. Or a dedicated polish as all three of these categories of products will effectively remove any embedded dirt.
The effect of removing embedded dirt is to restore clarity to the clear coat so you eyes can see through the clear coat to the beautiful color underneath.
If you're working on a single stage paint, the effect of removing embedded dirt is to restore the full richness of color.
Quickie Detail
After I decontaminated the paint I did a "quickie" machine wax using a Porter Cable 7424XP with a white foam Lake Country 5.5" polishing pad and Optimum GPS. I don't do a lot of quickie details, especially for cars like this but I was limited with time. Big picture though is the paint was cleaner, more clear and protected when it left.
