    M105 dries fast on cars not taken care of....

    On occasion I like to detail my friends, neighbors, etc.. cars if they ask me (usually after seeing my car). when I do this I always do a clay bar, M105, M205, and depending on person of what they think they will like NXT 2.0, or ultimate wax, or gold class wax.

    One thing I have noticed is that on cars not taken care of when using M105 it with my orbital the compound dries really fast vs on my car when I use this once a year it does not dry as fast or any car that has been taken care off over time by me.

    Dry as in crusty like and hard to remove by wiping with microfiber towel. It happens really quick also on cars that the paint has been neglected.
    So when this happens it always takes me longer than normal to detail a car because I have to work with a smaller space and wipe clean away.

    How can I explain this to myself why this is happening?

    M105 has a short working time. If it is over worked it will dry like concrete on the paint. Temperature and humidity also play a role.

    I am not sure what machine you are actually using but you should not need to compound after your first initial compounding unless you are spot correcting. Well that also means washing the car properly.

    Have you considered a more user friendly compound like ultimate compound.

      Paints that have been neglected are usually "dried out" because they haven't had any polishing oils / polymers etc rubbed into the pores of the paint and have been exposed to the elements.

      If the paint is dried out, then it will soak up M105 (or any other compound) very quickly. M105 is already prone to drying / dusting at the best of times, so using it on dried out paint will only exacerbate the problem.

The silver one demands nothing and it looks just fine. I think the black vehicle is taking advantage of me, and the silver car is more my style. We can go out for a drive without her makeup and she looks fine. If I want to take the black one out, it is three or four hours in the "bathroom" to get ready.

        Might be worthwhile to feed some M07 to the paint before polishing and see if it helps out a bit. Ultimate compound might be a better choice for compound as well.

            Agree with Davey g force
            im not sure if it's due solely to the stoddard solvent in the formula causing m105 to be too dry for my liking and many others but id certainly like to know what it is

            If there is one thing I hate it's compounds and polishes that are dry or too dry with short working times and water in oil formulas. Oil in water is better. I like to always buff with a lightly oily translucent film on the surface from start to finish.

            Abrasives in Meg's products are great however.

              How do you know so much about M105's formula? (Genuine question)

                Simple, read the msds sheet it mentions it there, check the cas numbers too.

                  Jock, it would appear your biggest issue is not so much that M105 doesn't like neglected, dried out paint, but that you're always using the same process regardless of vehicle and then fighting it when it's not the right combo. M105 was originally developed for body shop use on fresh paint, and typically that also meant rotary tool use with it. But as more and more detailers started using it on DA polishers on factory cured paints, we tweaked the formula ever so slightly to make it at least a bit more user friendly in that workflow. Personally, I have worked on just one car where M105 was totally unusable, and that was a Ferrari 360 Modena with badly neglected (I know, right, a neglected Ferrari!!!) and dried out paint. M105 instantly turned into a gummy mess on that car. Plan B. And you must always have a Plan B (and probably even a Plan C and a Plan D) since paints can vary widely.

                  Get yourself some M100; it's inexpensive, cuts like crazy, finishes beautifully, provides a longer buffing cycle than M105 in most situations - especially the ones like you're describing. Or get some D300 and microfiber pads; D300 will stay wet for a crazy long time, produces almost zero dust, and is even usable in direct sunlight on a very warm surface. We don't recommend that you do that as a matter of course, but sometimes a mobile detailer doesn't have a choice and is stuck in a less than perfect situation. D300/DMC5 is a lifesaver then.

                  Options are good to have, because the greatest variable you'll encounter is the paint itself.

                    Mr. Stoops,
                    On problem paint I've experienced the gumming of M105 that you mentioned. It was on my first use of M105 on paint, and black no less, and my first full correction on paint, and first time using a rotary on paint as well.

                    After hours of struggling and changing up my techniques to no avail I discovered one thing I had not tried with M105, that being (a suggestion by TuscaroraDave on AGO..due credit where credit is due) keep adding product to the pad until you reach the point that your using enough product that it can't dry out. Here's the entire thread. http://www.autogeekonline.net/forum/...-progress.html

                      When in those situations, I actually do the opposite of what Tuscarora Dave does. I spritz my pad with M34, and add minimal amounts of new product.

                      When you touch the face of the pad, and it feels dry and grabby (where a new, clean pad is relatively smooth), I can only assume that there are abrasives still on the pad. The M34 serves to lubricate the paint surface, activate dry abrasives, and aid the pad in staying damp.

                      Reducing the amount of product helps me control it. Even if it appears I'm "dry buffing" I still see film trails where my pad has been - so long as It's not hot, or in the sun.

                      Ultimate Compound has also proven effective in these situations.

                        That is good thinking for sure
                        Ideally though, there should be no need to do any of that if the formula of m105 was made better with no stoddard solvent


                        I have no time for any product that dries too quick,has really short working times and contain low grade solvents.
