    Questions about using M7, M21 and M26

    Hello everyone,

    First of all, my apologies if this already been asked. I did try to search the forum as well as rest of the internet, but could not find a definite answer to my question.

    I recently bought a new car and while washing it few days back I noticed two scratches and a few swirl marks. So I started digging on the internet how to fix these scratches and remove swirl marks. This is what I have been thinking:
    1. Clay the whole car. I have Meguiar's C-2000 Professional Blue Clay and D15501 Last Touch Detail Spray.
    2. M105 on two scratches with cutting pads
    3. M205 on swirls and two scratches using foam polishing pad


    Now, after fixing this I want to seal my paint and wax it. But I'm confused about the order. From whatever information I have gathered, I think following order is correct one:
    1. M21 Synthetic Sealant
    2. M07 Show Car Glaze
    3. M26 Yellow Wax


    I know that it is overkill but I am still going to do it. I'm also aware that M07 and M26 does not last long. Now, a few people stated that they would do M07 > M21 > M26. Others were doing M21 in the last. From what I understand, M07 and M26 both are oily and does not last long, if I use M21 on top any of these, M21 won't last long either, right?

    Please advise which order should be the best?

    Welcome to MOL!

    Let's address the removal of the swirls and scratches first. If you can feel these isolated scratches with your fingernail it's best that you do NOT try to remove them completely as doing so means you'll have to remove more surrounding clear coat than you should. Depending on the hardness of the paint and which cutting pads you're talking about (we don't recommend our own cutting pad on a DA since it's so aggressive) you may actually want to start with a polishing pad. Do a test spot first to see how the paint reacts; that will tell you if you're being aggressive enough with a polishing pad or if you really do need a cutting pad. Do the same with M205 to see if it's actually capable of removing all the swirls you want to get rid of. It can cut quite well with the right pad, tool speed, and paint type, but a test spot will let you know for sure before just jumping right in.

    Now, about your M21/M07/M26 application and it being overkill. Yep, you're right, it's overkill. Especially since you plan on using M205 anyway. Our recommendation: do your correction with M105 (or even Ultimate Compound as it's more user friendly on a DA and still quite potent as far as cut goes - it's based on M105, after all) and then really refine the finish with M205 on a foam finishing pad. This can add a lot of gloss and clarity to new paints, especially darker metallics. Then you can skip M07 and go straight to M21, with M26 as an optional topper 12 to 24 hours later.

      Mike,

      Thanks a lot for the quick and detailed reply. The two scratches I was talking about are little stronger than just swirls. After I washed my car, I had to be on a certain angle to see the swirls. This was not the case with scratches. One scratch does look like if you have rubbed a sand paper on it. I was thinking of using M105 only on these two areas. M205 on the swirls.

      About the pads, yes I have read that Meguiar's cutting pad is aggressive. I was planning on using hex logic orange for scratches and hex logic white for swirls. And then Meguiar's finishing pad for sealant.

      Sorry for asking this again, but if I am to use M07 as well, when should I apply it and how long should I wait before I wipe it off? and How long should I wait before I apply other things on top of it?

        You won't need M07 if you are going to use M205 then M21.

        As far as drying goes it depends on conditions etc.

        The order would be:

        M105
        M205
        M21
        M26

            M7 is pure polish, no cut. If you use M7 in the future, apply just before M21, do a panel or so at a time and wipe off before it dries. When M7 is all done, apply M21 ad remove then wait at least 12 hours (24 hrs or more if humid) then top with M26.

            Have fun this weekend. Just did my car couple weeks ago:

              An perfect example of how good M07 can be, especially on dark colored cars. Always remember to remove M07 WHILE WET, and apply in really really thin coats, it can be finicky to use, but worth the extra step. In the future, I recommend using it even for filling in swirls (instead of constantly buffing out swirls) that may have been inflicted by any mistakes in paint care.

                I will have to give M7 a try one of these days. It looks really good on a dark car.

                  It is really good on dark paint, try it, but keep in mind that it is a bit finicky but worth the extra effort. It basically enhances a paint's strong points. On dark metallic paint, it adds more depth and brings out the metallic flakes. I almost use it every time with NXT 2.0 on our Black SUV. Really adds a lot more depth and makes reflections even more crisp. I just with I had a bottle of Deep Crystal Carnauba wax, I would have liked to see how deep it would look, I have fond memories of DC Carnauba, I find it has more depth than NXT 2.0
