Carpro Glass Cutting Pad Confusion

[LeeH]

Hi All,

Which pad is the most aggressive glass pad? The black cutting pad does not seem (by feel) as course as the white polishing pad which is counterintuitive as it feels and looks more coarse.

In practice, I'm at a loss which one has more cut when using Ceriglass.

Cheers!

Carpro US says the black one is more aggressive.

I didn't even know they had come out with the black pad.

Thanks, makes no sense but I’m sure they are correct.

Reading the specs on the black pad, the bolded sections are what stands out for me -

WARNING: This pad is NOT for new glass or glass in good condition. This is for removing swirls and scratches in glass!

The 5" CARPRO GlassCUT pad is constructed of soft yet dense abrasive material that provides a textured polishing surface capable of removing etched water spots and light scratches. With slight cushioning that helps absorb excessive pressure and also creates a smooth polishing experience using minimal pressure, the GlassCUT pad is another great tool for glass restoration!

Best used with our CeriGlass compound, this product should only be used on moderate to severely damaged glass (visible scratches/etching). Always try to polish/clean the glass with a cutting compound like CARPRO Ultracut with a stiff foam polishing pad before using CeriGlass and a GlassCUT Pad. CeriGlass and the GlassCUT Pads are a much more aggressive option and should only be used at your own risk when the less aggressive options are not getting the scratches out.

Do you need the aggression offered by CeriGlass and the specific glass pads? I ask this because CeriGlass is horrible to use, being extremely messy and will ruin rubber trims. You also have to be extremely careful removing any splatter that gets onto the paint, its highly abrasive. Even though its your only choice when it comes to scratches in glass, it's going to take a lot of time and patience to remove even a moderate scratch.

If you are just wanting to clean up the glass, remove mineral etchings and overall improve clarity, you will achieve that using a firm/heavy cut foam pad paired with a heavy-duty compound or something like P&S Clarity Creme.

Yes, I’m using it for damaged double glazing. The white pads are working but is slow.

I find the residue to wipe off fine when wetted down again.

Thanks.

Trying to get scratches out of glass takes forever, even with a rotary. Dr. Beasley's has a glass polish which is supposed to be better then cerium oxide, I haven't used it. I was always intrigued with the 3M Trizact sanding system that's sold by Glass Technology (now known as GT Tools at gtglass.com), but of course they tell you that none of their glass scratch removal supplies should be used on windshields (ha).

That's par for coarse with glass, it will take hours to even make a small improvement, even with cerium oxide and specific pads.
