1. First image is just prior to buffing.

2. Second is just after buffing. Rear section (left) with M101/M205 combo, middle section (right) with M101 alone.

Please excuse the clutter in my garage, btw!! We are rearranging some things for the shop...

May post some more tomorrow in figuring this out...

Hello Everyone and thanks for the input and suggestions.

Ok, I hope these image uploads work. This is my father-in-laws hunting truck as you can tell and is 18 years old. Just as trivia, I painted the roof and hood 7 years ago and then buffed the entire truck as they hoped, at that time, to get a few more years out of it, ha. It's now 7 years later and only the second time a buffer has been put on it.

I hadn't planned on taking any images but decided to at the last moment so apologize I didn't get any better one's for you. The buffing depicted in the images was just after "one pass" with my rotary and polishing pad. Probably around 40 seconds of buffing or so... Note: I wasn't attempting to get every scratch out or a show-room finish. I just wanted to see what the rotary and M101 would do. I also did a comparison test of, 75% M101 with 25% M205 mixed in.


1. The first image is before buffing. You cannot see all of the scratches but they were extensive.

2. The second image is after the buffing. M101 alone was used in the middle section, whereas M101/M205 was used on the left (rear) and right (front of tire).

What speeds were you running with the MF disc and that polish mix
I have always believed in slowing the machine speeds right down when using a DA just like rotary
keep the pad clean by MF towel, brush or compressed air about 1 minute or 30 seconds before finishing that section and then do one final pass at low speed say 3 1/2 to 3 and 2 or even 1

if you have with a nice moist thin film of polish at start, middle and finish , you should finish out well 99% of the time with no marring
if it does change the polish to a finer one and if that still does it even with any technique, change the pad or do a follow up with softer MF or foam.

Re: Have Rotary Buffer and DA polisher, how to best use them together & what compound

Ralph,

That combination of Cutting Disc + M101 on a DA is quite agressive, so there is a very real chance of marring, especially on softer paints. Some harder paints (or white paint where you can't really see it, or cars which don't really require a show car shine) should finish up fine with just that combo. As you know, if you do get marring, it's no big deal to follow up with a finishing polish to remove it.

As for the photos, I always host mine on Photobucket (or another similar image hosting site) and then copy the IMG tag from there into my text on the forum.

Hello All,
Can anyone tell me how to upload images from my computer? The website is asking me to upload via URL website?

---------------------------------------------------------------------------------------------------------------------------------

Ok, so my view of the DA polisher has completely changed as I've been enlightened! My buffing pads began coming in today and I decided to test a spot on my 4-Runner with the new Meg 6in cutting disc and M101 (with 25% M205 mixed in). This combination quickly and completely removed numerous moderate scratches that I thought would be reserved for my rotary. I was really surpised.

I now have no doubt the DA is quite capable of removing moderate to significant scratches. This cutting pad is very aggressive and such that I've never used on a rotary. Is there any risk of paint marring with this thing and such as M101? It's simply amazing the DA could be used in this fashion with no expectations of swirls, holograms or marring.

I may well be using Detail..Australias scenario after all...

Input please,
Ralph

Nice. Yeah I will say this - have as many techniques and processes as you can
The rotary is still the king at creating a rich glassy wet finish whilst jewelling and a DA can correct a lot these days with the huge throw units up to 30mm today but the rotary does too.
Use them In any order you wish and always finish at a low speed and you shouldn't have too many issues if any.

Re: Have Rotary Buffer and DA polisher, how to best use them together & what compound

My 3step preference is to use a DA to correct then polish and jewel with the rotary at low speed then finish with a DA
why? - no marring from using DA for first step, rotary is better at enhancing gloss than a da and da last will guarantee no issues

That sounds like a well-conceived and reasonable strategy of which I might employ if a paint test spot were to prove tricky! For now, the rotary would be my go to for the greatest of corrections simply for its cutting ability. My strategy or mentality may indeed change as I get more familiar with the DA and it’s abilities though.

OK. I just got some M101 and I’m highly impressed with it. I've done numerous test spots on three of our family vehicles (silver, dark gray and hunter green). The hunter green vehicle is my father-in-laws neglected hunting truck which is faded and has an abundance of scratches. The M101 removed the paint imperfections as desired and with minimal effort. I tried it with both my DA and Rotary with 6.5in SoftBuff polishing pads.

The rotary made faster work of it and left no discernable issues (swirls, holograms) so I used it exclusively after that in attempting to see if any issues would arise. I didn't notice anything indoors but the sun is shining brightly today and I did notice two holograms on my 4-Runner. This however was only after a single step with my rotary and M101.

I must admit I was slightly disappointed because I thought it had “amazingly” left a flawless LSP ready finish. I really shouldn’t have been surprised though because I was being quite aggressive in that area. In addition, my technique has always been to lighten up on the rotary toward the end of a cycle to the point of no pressure. This always allowed me to finish out with minimal wiping which was important when I did this for a living and had to buff many auction cars in a given day. In this case, I may have overworked it though because the M101 working time wasn’t quite as long as I would like. It’s just going to take some tweaking (pad prep, rotary speed, pad selection, etc).

Anyhow, after spotting the hologram today I broke out the DA and went over it with some M205 and a polishing pad. The hologram disappeared quickly and with very little effort! The finish looks fantastic.

Note: Because my working time was slightly shorter than desired and M101 alone is more aggressive than I will typically need, I decided to mix a few ounces of it and M205 together (75% and 25% respectfully). I cannot say definitively at the moment but this did seem to extend working time and made clean up easier. In addition, there was no discernable difference in the cutting ability or quality of the paint finish when done.

I’ll follow up this post with a few images…

Re: Have Rotary Buffer and DA polisher, how to best use them together & what compound

I would recommend an M100, the compound works best on the Rotary plus the M100 tend to stay wet longer a well as this will not generate dust as much as an M101 or an M105.

If your boss vehicle has a minor or even some moderate scratches, With the DA machine alone, it still can get the job done very nicely and do not have have to use the Rotary ^_^

As for finising the job faster, Rotary is not necessary, If knowing the good combination what to use with DA, it can be as fast as using Rotary and the job wil come out even better too.
