Paint Leveling with HD UNO

[Thomas Dekany]

In general the softer the pad, the less product you want to use. If you polish with a pc, use hard pads like orange or yellow to level paint. Heck, put a 5" wool on the pc and go to town. If overworked, just slow the speed down and go over the area and that will help to wipe the product off without any issues. PS: With wool use less and the first pass should start on a slow speed to cover the area. Once the pad is primed keep it at speed 6. No matter what use use UNO with if finishes down so well. You will see. Let us know how it works for you.

Guess I have some more experimenting to do; that was about the amount of product I was using (3-4 dimes on the pad) but perhaps because it was one of the 5" DA MF cutting pads even that was too much product (after the pad was primed, that is).



Haven`t tried it on foam yet but I will do so on the jobs I have coming up this week to see if I get different results.



Thanks for the insight!

Barry Theal- Good write-up :xyxthumbs



Heh heh, so good that I`m tempted to say "you have too much time on your hands, go wash that Lincoln!" :chuckle:



But seriously, you and the other Uno-fans have me seriously thinking about it now.



So you don`t prime the pad as per KMB with this stuff?

Barry,



As the owner of a blue Accord, I found those before pics of the one you worked on horrifying! :soscared: but it doesn`t surprise me in the least, you made it look like it was never used :buffing:



For anyone at home who may have to resort to spot sanding with 1200-4000 grit discs, can we use a basic PC and a hook and loop backing plate to get similar results?



How is Uno to wipe off? Does it respond/look well after a IPA wipe and a final inspection?

So can you use HD UNO instead of 105/205? It looks like it took it down real good. Or do you use UNO then POXY?

The Mirka disks work well (both by hand and via PC), even for somebody like me who lacks Barry`s magic touch. There are, of course, numerous caveats.

You can absolutely use a PC with the sanding/finishing discs -- I use the Meguiar`s Unigrit discs on mine and the results are no different than you`d get with a pneumatic sander (unless the air DA you use has a 3/32" stroke -- which results in a finer scratch pattern).

I won`t speak to how wipe-off is since I`ve been having some quirky issues with that aspect of the product... but I can say that it does look awesome after an IPA wipe-down.

This is my thought/question as well

[Thomas Dekany]

If you overapply UNO, it doesn`t cut.

[TedFred]

Finally got the Uno/poxy deal the other day. I am dying to use it but am running out of cars. Not a pro like some of you guys.

[Alfisti]

How often do you need to clean the pad with Uno, and which way works best?

[Accumulator]

If you overapply UNO, it doesn`t cut.

So you do it the "regular old way" with an "X" or "ring of product" or "a few dots" rather than uniformly loading the pad?

[Thomas Dekany]

Few dots.......

OK, roger that...thanks for the info. I woulda overdone it priming the pad.

Thomas thanks for chiming in here with all your advice. Your experiance with HD UNO really shows. I can`t wait to watch you in action with it. I love to learn.

Accumulator,



I would recomend primming the pad in a uniform way. Heres why. Your not working the product till it drys away like a traditional diminishing abraisive. The abrasives won`t breakdown as they are non diminishing. So if something doens`t break down you want complete uniformity through out the polishing cycle. In order to do this pad priming is a must.



Look at it like sanding if your using it by a DA. Imagine if your sand paper only had an abrasive ring around. Or it only had abrasive`s spread in a X patern. There would be a really ugly mess sanding this way. It wouldn`t matter how much equal pressure you had. The rotation of the pad would be way out of sync. Everything would grab and pull. When the product is spread uniformly the abrasive is in constant movement. Constantly allowing the pad to move in a equal pattern randomly. If that makes any sense lol. you could look at it like this.



Imagine a sheet of metal spinning on paint. Now imagine the abrasive being marbles. With a ring of marbles as the pad spins it will leaves a constant ring with every rotation. The marbles won`t disapear at all, but will only bouce uniformly. Even know the bounce uniformly up and down they won`t cover all area`s and you`ll be left with circular lines everywhere. Now imagine if you had equal coverage of marbles threwout the entire sheet of metal. They would all be in contact at the same time, creating a complete uniform look.



Hopefully some of that makes sense! :twitch:
