I'll be the first to admit that sanding delicate, finicky, or thin objects can be intimidating.  Take automotive paint, for example.  Most factory applied paint jobs are literally as thin as two or three sheets of writing paper!  It gets worse-  a majority of the paint systems these days are comprised of a primer coat, at least one color coat, and a clear coat of paint.  

What does this mean in terms of our ability to safely sand defects or texture away?  It means it can be downright scary!  If, through sanding, you happen to remove too much of the top coat, the longevity of the paint may be compromised.  Sand through the clear coat, and a simple "Oops!" cannot begin to describe the extent of this seemingly minute mistake.  Bottom line- prepare to spend big bucks in order to properly straighten things out if you sand through the top coat. 

The good folks over at Meguiar's are well aware of how risky sanding automotive paint can be.  After all, they make all sorts of paint care products.  In fact, Meguiar's Unigrit® Finishing Papers are world renowned, and are truly the benchmark to which all other sanding sheets are compared to.  So when Meguiar's decided to develop a sanding disc system, they once again topped themselves by creating an entire line of Unigrit™ branded products. 

Most notable are the all-new Unigrit™ Sanding and Foam Finishing Discs, which are safe to use on automotive paint and plastics (such as headlight and taillight lenses).  

There are actually two separate sanding systems within the Unigrit™ System.  One is for sanding paint, while the other is for sanding hard plastics.  For specific recommendations pertaining to 3" discs, click here for a look at the Meguiar's Spot Repair Chart.

 Meguiar's Unigrit Discs are available in 3" and 6" diameters, and are designated as either a Sanding Disc or a Foam Finishing Disc.  What's the difference?  Great question!  The easiest way to tell them apart is:

• Unigrit™ Sanding Discs DO NOT feature an attached foam backing
  
  
• Unigrit Foam Finishing Discs DO feature an attached foam backing

As you might expect, Unigrit™ Sanding Discs don't have the ability to flex or contour as well as Unigrit™ Foam Finishing Discs, but they will level a surface much more efficiently. 

For jobs requiring the leveling of paint texture (commonly referred to as orange peel) on curved or complex shapes, implementation of a Unigrit™ Interface Pad between the disc and backing plate will increase conformability to the surface.  But, there's more to these discs than just foam, or the lack of it!

Each grade of disc has been optimized to do its job in a time-efficient manner, and to do the job effectively.  To see magnified shots and other features of each disc, click on its corresponding picture below:

Particularly noteworthy are the Unigrit™ Foam Finishing Discs, which feature a soft and pliable foam backing.  The foam backing serves three distinct purposes:

Regardless the type of Unigrit™ disc you choose, rest assured that you've got cutting-edge technology at your fingertips!  

                                  Sand by hand or machine... it's up to YOU!
Since not all sanding tasks require the implementation of a machine, Unigrit™ discs can be  used by hand.  To optimize sanding performance, Meguiar's offers 3" and 6" Professional  Hand Pads.  Simply attach the disc to the ergonomically designed pad, and get to work!

      Meguiar's Unigrit™ Interface Pads and Backing Plates take away the guesswork.
You've chosen your discs, but how will you optimize machine sanding performance?  Use the correct backing plate and interface pad!  The pros at Meguiar's thought of everything, and tailor made Unigrit™ Interface Pads and Backing Plates to work in tandem with Unigrit™ Discs.  Of course, they work well with other brands of sanding discs, too.
