Scratch-removal products for cars

Post by azurekep » Tue Feb 20, 2018 1:12 pm

My mechanic has a special formula for removing scratches from cars. Out of respect I haven't asked him to divulge the formula since in the past, he's done the scratch-removal for free.

His formula is vastly superior to the product I've used from an auto parts store. And I mean vastly superior. It's pretty clear that not all scratch-removal products are created equal.

What products do you folks recommend for scratch-removal, and do you have any home-brew formulas?

Start with Meguiars Scratch-X and just do it by hand. In my experience, it will remove most scratches.

If your clear coat / paint is hard, you can try using Meguiars Ultimate Compound by hand. Both of those are really safe to use, i.e. you cannot really damage your paint. A buffing pad with a Dual-Action polisher can also be used, and they are also relatively safe.

You can increase the 'cut' (i.e. abbrasiveness) by using different pad with something like a DA polisher for really deep scratches with the Ultimate Compound. Some of them are pretty safe, while some can really quickly cut through your paint.

Step 1: Remove contaminants
- Wash the car well
- 'Clay' the car, use the included lube ... ay+bar+kit

Step 2: Polish
- Purchase a Dual Action buffer
- Buff the deepest scratches with Meguiar's M105
- After 105, use 205 for final polish
- Use a Orange Pad with the 205, Blue pad with the 105
- All available from Harbor Freight!

Amazon ... eguiar+105 ... guiars+205

HF ... 60309.html ... 63291.html ... 62862.html

Step 3: Wax
- Apply your favorite wax

I went a step further on my wife's car and applied Nasiol ZR53 ceramic coating, but it's not for the faint of heart. Many go for a professional install ... ic+coating

And before you apply such a coating, you must make sure no wax remains. Use something like this: ... UTF8&psc=1

Follow all directions exactly, especially making sure no water remains on the car (ie. in trim and joints.)

I'm guessing you're talking about scratch hiding not scratch removal.

Assuming a 2-stage, basecoat/clearcoat paint (which most but not all modern vehicles use (e.g. there are still single-stage paints used, and sometimes tinted "clearcoat")...

To *remove* scratches (and assuming they are only in the clear coat not in the base (color) coat), you have to either abrade away the surrounding clear coat so that the lowest/deepest point in the scratch is now flush with the rest of the clear coat, or "paint over" the scratch with dabs of clear and then abrade away the high spots of the dabs so it's flush with the original clear coat.

Scratch hiding is the use of some chemical liquid or paste that seals the roughness of the internal edges of the scratch at a microscopic level so that it no longer reflects light and thus becomes hard to see (unless the scratches are deep). It will probably have to be re-applied periodically.
