Don't know if it's been posted here before (couldn't find anything with a search), so i thought I'd post a link to an Abrasiveness chart for compounds/polishes/glazes and pads that I found tonight.
Useful guide but can you tell me what the difference is between the (heavy,medium and light) abrasive compounds and a polish?
In terms of car products I used to think a polish was an abrasive.
JJ.......I'm not sure AR_Cool is on about but I printed it in "landscape" and it printed all but the last half inch........hope that makes sense :thumb:
lol o yes, I think some of the speeds are out due to meguiars not wanting you to wreck your PC. The rotary speeds are about righ, I normally work at 1500rpm.
It is useful, but I don't agree with some of it - Menzerna IP definitely has more cut than SSR2.5, based on work done over the last couple of weeks. Maybe we should create our own Detailing World chart? So much knowledge on here, about time we consolidated it?
^^I have been thinking about it lol now that the paint thickness meter is on board. It would be a lot of work and would need at least 10 different car panels to test, best of 3 etc.
It would need both financial and physical help lol!
I like the formatting on that page its a lot better than trying to do it with text in a forum post. The links to the original Autopia posts don't seem to be working for me. Here are some new links for anyone interested -

Will you be posting details of the 'Scottish Detailing Meet' in the Northern Region forum ? I would really like to see a demonstration of wet sanding then polishing out the marks with a PC.
I used Sonus SFX2 with my PC polisher (plus P21 Wax) at the weekend and felt that on one or two marks I needed something with a little more cut to it. I have a bottle of the Autoglym in the garage so would this suit do you think? Rich...
I would also like to know where AG PR is on the chart. I would imagine its Medium Cut if you compare to AG SRP. AG stuff is the most widely available since the Halfords and MotorWorld took it on.
also just wondering if anyone knows about red moose machine glaze, guessing its going to be fairly low, but just wondering if it has any cutting properties?
Does anyone have the facility to update this chart? Its really good and the addition of some more products would make it excellent, especially for :newbie:s.
My suggestion in understanding abrasive grits is to buy products that name the grit sizes:
600 grit - extra heavy for use after wet sanding or on a heavily oxidized single stage paint
800 grit - heavy can be used above
1200 grit - medium for single stage and some badly scratched clear coat finishes
1500 grit - light medium - for correction needs between
medium and light grit
2000 grit - light for use on clear coats
Micro Fine grit - for use on spyder scratches on clear coats
The problem you will run into here is trying to get your supplier to provide you definitive information on the grit size in their compounds. If you force the issue they might respond with information. But the chemists use this terminonlogy when selecting abrasives for the compounds.
They use either silica which does not break down as it is used or aluminum oxide which does breakdown as it is being use. But it has a tendency to gum up. So a good compound is one that uses a combination of both silica and aluminum oxide.
