I was using this product on an A3 as a polish after using 3M's perfect it fast cut compund. I used the Ultrafina with a Griots DA and a LC white pad, at a speed of about 4.5-5. After about 2 section passes it started to cake. I was using medium to firm pressure. It did a wonderfull job,I'm just concerned about the caking. Is this supposed to happen?? Was I using too much pressure; speed;
All input is welcome.

This product is only recommended for a rotary buffer, could be part of the issue. If the product is caking I agree with dougaross that you could be using too much of it, try cutting back on what you are laying on top of the pad and ensure you're priming the pad thoroughly.

If you are still having the same issue after experimenting you may want to consider switching to a DA compliant finishing polish like Menzerna PO85RD or PO106FA, the new formula Optimum Finish Polish looks intriguing as well.

Ultrafine (06068) is different than Ultrafina (50383), the latter is the UK/Euro version of the product and needs to be imported.

Let us know how you make out.
 
Both ultrafina and ultrafine in the US are the same product. There was just a name change when they went with the new bottles. You wont finde the UK version here as it is a totally different products and is not VOC compliant.

With your caking issues use less product and more speed. Ultrafina is designed for rotary use at 1800rpm.
 
Thanks for the input guys! Im actually in Europe and have the Ultrafina. I have used it before with the DA, but the difference was that i was using 3M's dedicated blue pad, at the same speed's. It seems to work better though with the LC white around 95% swirl removal. I did realize that I was using too much product, so maybe I'll cut back on that. Can you please link the priming procedure if its handy. I want to review how much we use to prime the pad.
Thank you!

Mike Phillips did a nice write up with photos on pad priming with a DA:

Assumed you were in the US...did not think GG DAs came in 220v.

:iagree:
 
I just read Mike's article again, and just realized something...
a quote "This can lead to pad saturation starting at the center of the pad where most of the heat is generated." At the end of my last pass I noticed in the center of the pad, where heat builds up most, the polish had turned into droplets, which were sitting on top of the pad!!!! Using too much product I can now understand. Could it be i was using too much pressure??

This is certainly possible. Ensure you are priming the pad adequately, and reduce pressure on the DA as you finish a polishing cycle. Also, before you start drastically altering your technique you may want to consider the following:

* You are using a line of products that are recommended for a rotary polisher on a DA. That is not to say that it cannot work, as you state in your original post that you are pleased with the finished results, but you may want to try again with a DA-friendly line of compounds/polishes first.

* You are moving from a compound directly to a finishing polish which seems like a big jump, why not instead move to the next step polish in the 3M system (3M Extra Fine)? This should level the compound induced marring quicker than the Ultrafina, therefore negating the need to work the Ultrafina beyond its buffing cycle. Depending on the level of defects the compounding step may not be necessary, likewise, the finishing step you are using Ultrafina for may not be needed, as the 3M Extra Fine Polish may produce the desired gloss. A test spot will be the indicator on the best approach here though.

Keep experimenting and let us know how you make out.

Good advice Shawn. IMO Ultrafina is a jeweling polish and should be used as a finishing polish and not to remove scratches.

I just realized i made an error, I did use the extra fine (yellow cap) not the fast cut. Sh*&^(&( sorry guys!!
This is why I was pleased with the results. And following 3M's recomendations used the ultrafina to polish as the final step in their 3 step process. I didnt use fast cut cause the defects weren't that bad. I was just puzzled by the UF caking! I just read somewhere that you should finish the UF with a slight oily film left on the panel, and not dry buff!! Point well taken.
I do realize that these are for rotary use, and will upgrade to one once I feel comfortable with it. I was actually surprised that these products worked so well even with a DA.
Tomm hopefully I'll finish the hood. I'll take all the points given about prepping etc, and post results.:buffing:
Thanks for the all the help!!!!!!!
