Trouble finishing

[detailfan618]

The other day I was doing some paint correction on a jet black 335i. I used 105 on an orange LC pad then followed up with 205 on a black lc bad. The 105 did a great job but after the 205 step I could see my stroke patterns in the paint. I have never had this happen. The only thing we can think of is that it was significantly colder in the garage than what we have ever polished in. Has anyone had this happen before?

What machine are you using - I assume a rotary? If so, then I assume the 'stroke patterns' are holograms/buffer trails and your best bet may then be switching to a Dual Action type machine for the final polishing step?

Mike (Dedicated Perfection) has some experience with Jet Black BMW paint and may chime in with some tips?

Work the 205 longer rotary or not never seen stroke pattern.Black pad is to soft for 205.usually working on BMW with those 2 products best results come from micro pads.1 to cut 1 to polish with 205.make sure the pads are clean either with rotary or da.

What type of tool are you using?


IF you're using a rotary buffer then you're seeing holograms.

Holograms are a SCRATCH PATTERN that is SPECIFIC to rotary buffers.


If you're using ANY type of free spinning orbital polisher then the scratch pattern is called micro-marring and the pattern is buffer trails.



My experience is the BMW Jet Black, non-mettalic paint is on the medium to soft side of the paint hardness spectrum and it micro-mars or scratches easily.


M205 is a SMAT product and many people find it challenging to finish out to 100% perfection on softer paints without spending more time and more technique as compared to quality DAT products.



So... what type of tool are you using?

Yes, I have been in that exact same scenario with both of my Jet Black e9x BMW's...

As mentioned by Lawrence, what machine are you using?

I highlighted an important note above in Mikes post.

Before we all go off the deep end whereas members say that technique is the most important factor, have a read through the link and pay attention to what Mike has to say.

I am using a torq 10fx. So if M205 isn't the polish to finish with what is?

By the way thanks for all the responses. I really enjoy having this forum to lean on when a question arises. Now time to go look up SMAT AND DAT

I am not sure if I am just not looking in the right places but I have found some information on SMAT and DAT but how do I know what one of those categories a polish falls into?

Basically all of the modern Meguiar's compounds and polishes are SMAT (super micro abrasive technology) including: M105, M205, D300, M100, M101, Ultimate Compound, and Ultimate Polish. Each manufacturer has their own way of advertising "non diminishing" abrasive technology. Generally the label will say something about micro/nano abrasives or it will literally just say that it is a non-diminishing product. SMAT products will typically have instructions like to "work the polish until the product begins to dry." DAT (diminishing abrasive technology) will usually state somewhere in the instructions about working the product until the abrasives are broken down.

It's not necessarily you or the fact you are finishing with a rotary. I have been using a rotary and M205 to finish for years and I can tell you that due to the high concentration of "trade secret oils" if I'm working on a sticky paint system I've found it's best to just use a different polish all together. While it can be done by adjusting techniques, machines, pads, etc... if you are working with m205 on a sticky paint system it's not worth all the extra time you'll spend doing an IPA wipedown after each pass to remove the oily haze m205 left behind. Luckily I've found that when I do have this issue (especially when working on single stage lacquer) I just swap it out for HD Polish+ because for some reason if M205 doesn't work well, for some reason HD Polish+ actually works even better than usual.

One other thing to consider, if you do think it's sticky paint and m205 isn't removing clean, if you don't want to order HD Polish+ I would recommend getting some edgeless low-pile 245 microfiber terry towels from TRC.

Before, when I had this happen, I'd reach for my Menzerna SF4000, or Rupes Keramik.

This article changed all that for me so far.

I never saw that, Thanks

So if M205 isn't the polish to finish with what is?

Menzerna SF3500.
Menzerna Nano Polish PO 106 FA, Menzerna Final Polish, Nano abrasives, finishing polish, professional polish (http://www.autogeek.net/menzerna-nano-polish-po-106-fa-finishing-polish.html)

Meguiar's ultimate polish has less cut and more polishing oils than M205. So that is always another option. Yes it is still a SMAT product.

How did the paint look after M105? Did it have DA haze or micro marring left over from the correction process? Perhaps try M205 on a polishing pad instead of a finishing pad. Experienced this myself on a corvette that was repainted.
