Product Review: Meguiar’s Unigrit 1000 and 3000 Foam Finishing Discs

Meguiar’s Unigrit 1000 and 3000 Foam Finishing Discs are a great product for any experienced detailer to keep on hand, whether spot sanding minor defects on painted surfaces or fixing your oxidized headlight lenses.  The Unigrit discs are available in both 3″discs for spot sanding or 6″ discs if you are color sanding an entire exterior of a vehicle.

As with all my product reviews, here is the product description as provided on Detailed Image.

Product Description

The Meguiar’s Unigrit Finishing Disc’s make removing fine imperfections from your paint fast and easy! It can help you remove scratches, water marks, bird droppings, orange peel from the paint or restore oxidized and faded headlights. These ultra fine sanding pads are very user friendly as they help quickly remove blemishes with little effort and bare minimal haze, if any at all. Simply attach your Meguiar’s Foam Sanding Interface (3″) to your buffer and the hook and loop backing on your Unigrit Finishing Disc will secure the pad to the interface. Spray the Finishing Disc and the area you want to sand with some water. On a lower speed setting using minimal pressure buff away the imperfections just like you would with a polish. We recommend checking your work and cleaning the pad frequently. To clean the pad, spray the pad with some water and run your finger or a clean microfiber along this pad to remove any residue, it’s that simple! We always recommend starting with the least aggressive sanding pad and working your way up to the more aggressive pads as needed. If you are looking for an easy way to remove noticeable imperfections from your paint, look no further than the Meguiar’s Unigrit Finishing Disc’s!

During my review I used the 1000 and 3000 grit discs for a headlight restoration on a severely oxidized set of lights.  The Unigrit 1000 discs worked very quickly at cleaning up the sanding marks caused by the 600 grit sand paper used in the previous step of the head light restoration process.  You will need to keep the disc wet in order to prolong the life of the disc.  I like using air every so often to blow the disc off in order to keep a nice clean face.  It is also important to keep the disc clean in order to achieve the maximum amount of correction and cut.

The Meguiar’s Unigrit discs can also be used for more than just head light restoration jobs.  They are great for spot repairs to remove scratches or orange peel removal before compounding and polishing.  You need to be extremely careful when doing any type of sanding on the finish of your vehicle, and be certain that you have enough clear or paint to work with before proceeding as it does not take long to cause damage if not done properly.  It is always critical to take some paint readings with a tool such as the DeFelsko PosiTest DFT Paint Thickness Gage or even the Highline Meter Paint Thickness Gauge as most factory clears are very thin.  You will also want to use the interface pad along with the discs when working on paint as this will allow the disc to properly conform to surface greatly reducing the chances of damage.
