Re: Why not speed 6 ?

What others have said about the stresses on the velcro backing and the associated heat build up are spot on. A rotary buffer doesn't do this since the tool isn't forcing the pad to change direction constantly. As a result, the majority of heat generated by a rotary is the point where the pad meets the paint. With a D/A the majority of heat generated is where the pad meets the backing plate - and it doesn't have the opportunity to cool down like the paint/pad interface does since there's no air flow and no fresh, cool product applied to it.

But that doesn't mean you can NEVER use speed 6 - you just shouldn't use it for extended periods.

The same holds true when using a cutting pad on a D/A. We don't officially recommend the practice as these pads tend to be aggressive enough that they very often haze the paint. Yes, they can pull out more severe defects, or defects on very hard paint, but the resulting finish usually isn't very pretty and requires a follow up to fully correct. Not always, mind you, but more often than not. Again, this doesn't mean you can NEVER use a cutting pad on a D/A - just be aware of the possible outcome and try not to use it on the entire vehicle.

thanks for all the info guys...has anyone used to burgundy cutting pad on the g110 with good results ?

There is a lesson to be learned here. Do your details on Saturdays. Then it would always be the weekend. lol.

Re: Why not speed 6 ?

I once used speed 6 but the force was so great it reversed the earth's rotation and caused time to go backwards, like in the first Superman movie. I was mad because I lost 8 hours of polishing and all my swirls came back.

But my neighbors were even angrier because I did this on a Friday evening and backed up time to Friday morning, so they all had to go back into work.

I wasn't invited to the block party this year...

Hilarious!!

Re: Why not speed 6 ?

The reason for not running it on speed 6 is the machine gets hot and will transfer heat to the backing plate and can either break/snap it, and the foam pads will shred/tear up and the velcro will come undone. Not to say you can't use speed 6 with good results (at your own risk), but Megs doesn't recommend it for a few reasons in which are mentioned above.

Re: Why not speed 6 ?

Yep, in fact I just had to retire a backing plate for this very reason. Pads won't stick to it anymore

Interesting information.
Had the same experience, but it wasn't destroyed like the one shown in Lasthope05's post.
The pads would not stay in place and I just figured the backing plate had worn out sooner than I would have expected.
I guess that was the case, but it was more my fault in the way I used it than any lack of quality in the backing plate.
Thanks for the explanation.

Re: Why not speed 6 ?

wow..ive never seen that before !

Re: Why not speed 6 ?

Because the twisting and turning action of the DA puts stress on the pads and backing plates loop and velcro. The increased speed would be putting excessive strain on the two at higher speeds and pressures.

It happens.

Exactly - the velcro loops break and the pads wont stick any longer

Re: Why not speed 6 ?

I use speed 6 all the time. The downside of speed 6 is:

- reduced backing plate life
- reduced pad life
- greater chance damaging paint, especially with mini pads

My philosophy is to use speed 6 only when necessary to remove defects while compounding. For regular polishing, speed 5 is fine.

i can see the point of reducing pad life, thats just normal..but reduced backing plate life ? how does this happen ? the backing plates are pretty darn sturdy how could they get damaged over time ?
