Asked by GeneJr October 29, 2019

This is a great machine, but if your rv has a lot of oxidation it might not be strong enough to get the finish you want. Make sure yu have a cutting pad, and a finishing pad and ABSOLUTELY the right compound and polish. If there isn't any oxidation get an "all-in-1" Which is a polish and sealant in the same product. Will make your life easier and no will not leave swirl marks, but take your time and you'll be fine. Good luck!

Can I use this to remove dried, old wax on the hood of my car??

Asked by TrustNoJuan September 8, 2016

Actually the first thing I used it for was to remove heavy oxidation from the roof of my 14 year old pick-up caused by the harsh central Texas sun, with clear coat safe rubbing compound. The paint now looks new again.

How many watts as I will be plugging into a 700 watt inverter.

Asked by Dondadondon May 29, 2016

Brush electric tool use a lot of power, you can plug first in the regular outlet and compared the tool efficiency. Both, the generator and tool must to work relaxed.

Can you change the backing plate on the polisher so you could end up using a smaller pad for tighter spaces?

Asked by Brandon April 3, 2016

Yes, will take a 5 and 6 inch backing plate or 4.

Professional Quality - great for sanding and polishing
I have owned this sander/polisher for over three years and it has handled everything I have thrown at it - from sanding 1,200sqft of old deck boards (yes, I am crazy!) to compounding and waxing my boat (restored 20 years' of fade and haze to a like new finish), and fine finish sanding on furniture refinish products. I highly recommend this product and would buy again if mine ever craps out.

Great Kit & Great Results
Purchased this along with Chemical Guys V32, V34, V36 and V38, plus a sealant to detail two vehicles that have swirl marks and scratches. One vehicle down, one to go, with amazing results!

Just tried this buffer with the V line compound and polish. Very happy with the results. Tested on a junkyard door that was very scratched.

Detail Kit
Although I thought I'd be receiving the Torq. DA I'm more than happy with the kit I received. Detailed my 2012 Camry that has been exposed to the harsh New England winters with absolutely no garaging since day one. Being Midnight Black I had my doubts but the products recommended the training videos on line the car came out awesome the finish is like glass. Can't wait to do the rest of my fleet.

Performing much better than I expected
I have been looking for years to polish the glass in our boat. Water spots and scratches were the problem. After watching your videos i decided to purchase. The results are very good. I think after some more use, i'll get even better at it. I don't know of anyone else using these products in the marina but, I've had many folks come by and want to know how to do it. In the photo, the glass on the left is not wet. Glass on the right was polished. Other photo is looking out the rear transom. We are very happy.............

Awesome Products!
I bought the Porter Cable kit and bought the polishing products. I have to say, WAY beyond expectations. I have never used a buffer before in my life and this was super easy with the online videos from the website. I have a 2010 Yukon Denali XL that has never had any kind of treatment like these products give. I had swirl marks everywhere from taking it to the car wash and using the brush along with having a dirty wash mit. I used only your typical wash wax Combo products and it was clean....but not like this. I started in the hood with the level 32 and worked my way all the way up to the polish and it is amazing. Swirl marks are gone and the shine is unbelievable. Hard to tell it is a 2010.
by 2010 Yukon Denali XL
Exceeded expectations
One of my cars had crazy clear coat damage and the extreme compound took it off. My other car had scratches like Edward Scissorhands washed it 100 times. The extreme compound removed those as well. I tried 2 other brands scratch and swirl remover and they didn't work
