Yesterday, I did a little bit more of YouTube University, then went back out to the Pig Barn just to clean up my shop but couldn't leave the hood alone.

I started with my Makita, a white (medium) pad and the Chemical Guys V36. Looked great until I got down at the right angle and could still see scratches.

Not knowing what I am doing, so I dug out an Orange pad and used the M100 with the Makita. I could still see scratches. Very disappointing and frustrating.

I then used the same pad and M100 but on my Dewalt DWP849X polisher. It was like a magic eraser for scratches! I still need to do the next two steps but it is definitely working now.

There are a few spots that I need to go back on, mostly at some of the hard edges that I was kind of scared of burning through.

What's the difference between the two buffs? I had a Makita which I replaced with Hitachi - basically the same except for the colour, and the price. Also have Bosch blue (light but noisy) which seems about the same in terms of effectiveness and a couple of cheaper brands that just take up space. So interested in why the Dewalt was so much better.

Well, since I am pretty new to most of this stuff, I would guess that it was more of an issue of operator error versus the machine differences.

The Makita is a Dual Action Random Orbit Polisher with a 7.8 amp motor while the DeWalt has a twelve amp motor, is not a Random Orbit and is definitely heavier.

The Makita also has a forced rotation on/off switch that I may or may not have had on the correct setting - I "think" that I had it set to forced rotation.

But like I said, it was probably more of my rookieness that was the issue. Again, just that one nut causing problems!

Ok, ta.

Yes, I can understand why such a big difference now. The rotary will have a huge advantage over the DA for dealing with scratches. But the DA will give a nicer, swirl-free finish when polishing.

I have a Dewalt buffer with variable speed trigger so I can start slow and then speed it up.
Start with a twisted wool pad and Meguiars M100. Run the buffer at a lower speed to start working the compound over a section of the panel and then bump the speed up to 2500 RPM and continue to buff the area with a smooth, continuous motion. . .


Way back on page 1 of this thread. :wink:
