Twisterspecial,

First off, DACP should NOT be applied by hand. The DA is DACP stands for Dual-Action which refers to the Dual-Action Porter Cable Polisher. I would definitly stay away from using this by hand in the future.

Second, the best way to tell what works is to do a test spot. I would take some #80 or even #82 on a polishing pad and do an area maybe 2' x 2'. Examine the area and decide if you need to go more aggressive with DACP. If you decide to go more aggressive use DACP on a polishing pad and work very slowly to let the diminishing abrasives work. This is why DACP should not be applied by hand.

Lastly, here a few tutorials to teach you how to include images with your posts.

Good luck! If you have any further questions don't hesitate to ask!

Re: Which Product - DACP or Speed Glaze

I have a few water spots on my wife’s 2002 Tahoe Z71. I took some DACP and using a foam applicator I applied it by hand. Using a Micro Fiber towel, I removed the DACP by hand and the water spots were removed.

My question is, I want to repeat the process on the area's I have water spots, but since I have a PC with all of the various Meguiar's pads, I would like to use my PC instead of doing the vehicle by hand.

Following Mike Phillips information on using the LEAST abrasive product first, should I purchase some speed glaze and try it, or should I use the DACP with a W-8000 Pad. The vehicle has a few swirls in the paint, so I am mainly after the water spots. I will follow with MPPP as I have done in the past.

Thanks,
Mike

Hi Twisterspecial,

A couple of things, #83 DACP is formulated for use by machine, you can use it by hand, but best results are achieved when machine applied.

Over the weekend we held a detailing clinic for members of the G35Driver.com website, one of the guys, Vic, had water spots all over the hood of his car. He successfully removed them all using the #80 Speed Glaze with a W-8006 foam polishing pad on the G-100 at the 5.0 setting, hopefully this will work for you also. Remember, sometimes it may take a couple of applications to remove the defects.

And just one more comment, it's actually Meguiar's that started the philosophy of using the least aggressive product to get the job done, they've been teaching people this approach since their inception in 1901, almost 60 years before I was born.

Good luck!

Mike

I'm glad Chris brought this up, allow me to clarify,

Chris is just a little off in his answer, it's okay Chris, because it's mistake that a lot of people have made before you. #83 Dual Action Cleaner Polish does not get its name because it's intended to be used with a dual action polisher... it gets its name from the fact that this polish offers two types of actions

One - It starts out like a paint cleaner because it contains Meguiar's unique diminishing abrasives which abrade the finish and remove defects. This is the cleaning process this product performs.

Two - As you work the diminishing abrasives into and against the finish, they breakdown. Because they breakdown, they can start-out aggressive to remove defects but as they breakdown they continual polish out any remaining defects including any they put in as a part of the cleaning process. Because all Meguiar's polishes, including cleaner/polishes and pure polishes contain Meguiar's Trade Secret Polishing Oils, Meguiar's polishes lubricate the surface to prevent scouring and scratching which results in a finish that always has a clear, high gloss appearance.

That's where #83 Dual Action Cleaner Polish gets it's name, from the function of the product, not one of the machines it can be used with.

Second, the best way to tell what works is to do a test spot. I would take some #80 or even #82 on a polishing pad and do an area maybe 2' x 2'.

This is good advice, and advice I have been preaching for around 15 years, and that's to do "Test Spot". Make sure your choice of product and application method is creating the results you're after in one small area before duplicating the process over the entire finish. It just makes sense and can help prevent an awful mistake.

Examine the area and decide if you need to go more aggressive with DACP. If you decide to go more aggressive use DACP on a polishing pad and work very slowly to let the diminishing abrasives work.

So good, so far.

This is why DACP should not be applied by hand.

Meguiar's recommends using products like the #83 DACP with a machine for best results. However, there are plenty of people that have used the #83 by hand and achieved stellar results, Scottwax being one of these people, so remember,

I have never met a water spot that MPPC didn't remove. I think you may find this to be a better solution than 83 if you are not after the swirls.

Mike,

Thanks for the clarification! I never knew that about DACP, I always just assumed since it is meant for the PC that that is what the DA meant. Thanks for the info!
