    Menzerna or meguairs for deep scratches and acid rain/water spots

    I'm seeking advice on which product works best with either a blue cyan pad or a microfiber pad for heavy correction. I've seen the fg400 and m101. Are either of those what I need? Thanks

    You pays your money and takes your choice. If it was me I'd go with the FG400.

    I haven't used M101.

    FG400 is a true giant of a compound.

    At the end of the day I would imagine that using the appropriate (in terms of cut) polish from either Meguiars or Menzerna wouldn't really effect the outcome - its more about the journey getting there.

    Meguiars uses SMAT abrasives (lots of really tiny abrasives that don't break down) whilst polishing and Menzerna uses DAT abrasives (larger but get smaller the longer you work them). The difference in how you work them is Menzerna will need to be taken through its full buffing cycle to allow the abrasives to properly breakdown (let's say 6 to 8 passes) whereas with Meguiars you could stop after 1 pass if that is all it took. If however you 'over-worked' the SMAT abrasive the 'debris' (as Larry likes to call it) - i.e. spent polish, and the paint you have abraded off the car) will clump around the abrasives and actually start scouring the finish.

    Well that's my understanding anyway.

    I am a huge Menzerna fan so FG400 (or SHC400 as it is now known) would be my recommendation.

    If you truly are looking for something with heavy correction, SHC300 will cut more, but it doesn't finish anywhere close to FG400 and so a follow up refining polish will be required.

    Microfiber will also out-cut foam

    You didn't mention the type of tool you are using?

    Someone could assume a dual action polisher?


    Also, what are you working on?

    Yes sorry a Da polisher. I get various vehicles that have been neglected and look like they have been washed with a Brillow pad lol

    I've used various compounds like pinnacle etc with a blue cyan and it's not enough. More goal is to find the easiest way to get there And not have to work myself to death

    There's a compound in Pinnacle and two polishes. The compound is as aggressive as any quality compound on the market.

    To get more aggressive you need,

    More aggressive pad
    More powerful tool.

    I have numerous articles on this forum where I buff out trashed cars in under 6 hours using the FLEX 3401.

    Another option is to start with a rotary and finish with your Porter Cable to avoid holograms.

    Another option is to get the GREY THINPRO pad and trudge through the compounding step with your PC.


    I taught a couple of newbies how to machine polish on an expensive paint job with water spot etchings. They wanted to use safe tools like the PC. So I amped up the PCs ability by added the grey ThinPro pads.


    Click the link, look at the before pictures, read the text and then look at the after pictures.


    1955 Chevy Bel Air with a $15,000.00 Custom Paint Job - How to remove water spots








    Here's an excerpt...

    Test Spot 3: We switched over to the 5.5 inch ThinPro Gray Extreme Cutting Pad while sticking with the McKee's 37 Fast Compound. This did the trick. The thinner, much more aggressive foam cutting pad with the McKee's 37 Fast Compound completely removed the water spot etchings with the normal 8 section passes.



    Car came out pretty good...





    Notice most of the guys in the background are using the FLEX 3401 with LC Orange Hybrid pads, (cutting pads), more power, faster results. The FLEX 3401 aka the BEAST!

    How much extra work and time would the Grey Thinpro pad and the PC take compared to the other tools and methods? Examples being the Flex, Rupes, and rotary.

    Thanks,
