How does DACP work?

[k80]

I have been a user of DACP for some time now and allways get good results when applied with my PC. It crossed my mind last night how does DACP actually work? Does it remove a thin layer of the clearcoat to remove the swirls and scratches? How does a product like DACP differ from a T-Cut product?

Many thanks

Hey,

A very simple overview.....

Meguiar's #83 DACP contains Diminishing Abrasives that start out large and gradually break down to a really fine polishing product. The results are the swirls are removed and the finish is then polished removing most, if not all, haze from the product itself.

The only way to remove swirls or scratches is to level the paint around the marring. Mike had an excellent diagram that I just looked for but could not find. I will post it when I find it. Essentially, if you could take a cross-section of the paint and look at it from the side, swirls would be sharp depressions/grooves in the paint. Again, you must bring the paint down around the grooves to the groove's lowest/deepest point. This in effect, "levels the paint."

Just a basic overview. I hope it helps!

Here's that diagram, (just type in the word "Diagram" in the Photo Gallery Search option)



Also, just to clarify, the diminishing abrasives start out large and then breakdown under time and pressure. But the word large as it's used here is relative to the product.

Next time you're using any of the 80's series products, shake the bottle well and then pour some product onto thumb or index finger and then rub your thumb and index finger back and forth...

Do you feel anything gritty or abrasive?

The correct answer is "No". That's because all of the 80's series products use different types of microscopic diminishing abrasives. If you want to feel a comparison, then the next time you're around a bottle of any of these products,

• * #1 Medium Cut Cleaner
  * # 4 Medium Cut Cleaner
  * #44 Color Restorer
  * #49 Oxidation Remover
  * #67 One-Step Compound

Shake the bottle well, and then pour a little bit of one of these products out and rub some between your fingers and feel it. These products use diminishing abrasives that you can easily feel and relative to the 80's series are large.

Also just to add to this lest their be any confusion, there are a plethora of different types of diminishing abrasives available for Meguiar's to use in a formula and Meguiar's R&D selects specific types to perform specific tasks for different products.

For example, the diminishing abrasives in our compounds take longer to break down than the diminishing abrasives used in a product like the #80 Speed Glaze. What ingredients are used in a product is always determined by the purpose of the product.

Hope this helps...

Thanks Mike and 2hotford you've cleared that up for me.
