So I've got a Porter Cable 7428 to play with for the winter

Thanks first to William H. Bonney for sending it to me to try.

I picked up a fender from the body shop owner I know, unfortunately, the only one he had in decent enough shape was white.

Anyway, it has been 28 years (since I was in high school) that I have used a rotary so I did some practicing today with the 7428 and the fender.

1. It seems to take more polish than the PC, Cyclo or UDM, seems to clear out and dry quickly and I get some hop.

2. Even bumping it up to 4 (speeds are 1-6, not rpms

) and using Optimum Compound and a Meguiars burgandy cutting pad, I couldn't burn an edge even using moderate pressure.

3. Correction is definitely faster than a DA/RO buffer.

4. Even with halogens, I didn't notice any holograms when I was done-finished out with Optimum Compound and a yellow Meguiars polishing pad. Looked LSP ready, in fact.

5. Hopefully I get time in the next few days to practice on my car...probably best to do that before using it on a customer's car...although I am pretty confident if I keep the speeds down and stick with polishing pads I'd be fine.

If you wanna give my Hitachi rotary I try, I don't mind sending it down to you, seasons done for me up here. It's been the most solid rotary I've used.

WOW scott using a rotary never thought I would see the day

What made you decide to use a rot?

Plan on using them on alot of customer cars or only the bad ones?

Someone offers me a rotary to try like Ryan (WHB) did, I'm going to take them up on it. Plus, I have customers with Audis, CeramiClear Mercedes and Corvettes so I need to get up to speed with a rotary to fully correct those finishes.

WilliamHBonney · 12-03-07, 10:29

Scott, I have had it up to 5 with SIP and a burgundy pad on clients corvette and it never burned. Only time I have ever burned is on single state paints.

Advice Scott, get another pannel and try to burn it by going up to speed 6 if need be.

DieselMDX · 12-03-07, 10:38

I hear ya on burning i have been using my hitachi a little bit but dont turn it higher than 1100.

it does correct alot faster

I dunno guys, burning is ALOT harder to do than most people think. Ive had the Makita at ~~2000 RPM with a yellow LC pad (really really hard infiniti clear) and didnt even come close to burning anything.

The rotaries are alot safer than most think. Man I wish I had mine still!

Have any of you tried or heard about this new Flex 3401? I hear this is a good piece of
equipment.

I would say that burning paint is really a "paint-dependent" issue.

All paints respond differently to different pads/polish combos, so I would just say to anyone "watch out." I have seen paints burn @1500 RPM's with a Meguiars polishing pad--especially on ABS bumpers. Learning the rotary is as much about learning different paint systems as it is learning to control the tool--IMO anyways.

Good luck it Scott, it will come natural to you as you know the nuances of paint systems.
