One unfortunate day, my car’s driver side wheel arch along with the front bumper brushed with a White Ford Fiesta (cab) which was carelessly parked blocking path. There was a complete 4” x 3” white patch, initially I miss took it to be the primer of my car. Thanks GOD and thanks Ford, it’s just the white paint of the cab.
I have tried all the methods (car wash shampoo, rubbing with soft to rough cloth and even tried with my nails to scratch it out) to remove the white paint impression failed. My friends suggested a paint shop job, but I am not convinced without giving a try from my end. Since this is covering both the metal part (wheel arch) and the plastic part (bumper).
Finally I thought of buying a polishing compound to do this job. As I am familiar with “Formula 1” products, I planned to buy “Scratch Out”. There are two products available in the same name, but in different form “liquid” and “Paste”. To my surprise, there are no clear differentiations between both the products even in their official site, but I went for the Paste since its bit costlier than the Liquid. This is what they advertise:
• Heavy-duty paste removes the toughest paint problems from all finishes.
• Extra strong to remove moderate scratches, bird droppings and tree sap.
• Restores paint color, making paint finishes look like new.
• Won't scratch clear coat paint like conventional rubbing compounds. Before I write my personal opinion, let’s see few things. Some paint defects A close up look on scratches and “Law of reflection”
Basic science teaches us, that, when light hits a surface, the rays of the light are bounced back and this is called reflection.
When the surface is plain and shiny, we get the best reflection; if the surface is rough and uneven the light reflections is scatter, which helps us to identify the rough/uneven surface. Light Reflection vs Plain and shiny surface Light Reflection vs Rough and uneven surface Role of polishing compound in the above case
Polishing compound is made of micro abrasive particles, which are rubbed on the rough/uneven surface to smoothen the scratch marks and make the surface even.
That is scratching the clear coat and smoothen the uneven and rough surface to near flat and plain. (Please note that we are removing some portion of clear coat (very little) and smoothen the harsh scratches) By doing this we get a plain surface and this reflects light higher than the uneven/rough surface. This obviously gives some reflection, which in terms increase the shine on the surface.
So this is just a Cosmetic makeover and not a permanent cure and more over this polishing doesn’t end here, and to will fill the gaps waxing is must after polishing. Only this produce a fresh clear coat look and shine. (For deep scratches we can use clear coat pens (Fix it Pro or equivalent) to fill the wounds which is more effective than wax)
Coming back to my personal experience, I have removed all the white paint impression with the help of this polishing compound.
I have tried the “Scratch out” on my OVRM, where clear coat was damaged when a cabbie hit my OVRM with his OVRM. Damaged clear coat with matt like finish. (Before polishing) Repaired clear coat with glossy finish. (After polishing and without waxing) In my personal opinion it works as advertised. But don’t expect a magic or miracle this will only help you smoothen the surface for higher reflectivity.
