GG 6" Rop polishing speed and model question

[DaC]

I'm wondering if I can polish a car using only speed 3 in GG 6" ROP and still get correction power ? I'll use LC 6" HT Kompressor pad with LC 5" backing plate
I'm asking this because noise is really a concern as I live in a apartment building...
Also, my model is the 25 foot and I realized it has a different recommended speeds emblem..... did I got the old GG ROP model ???
here is a picture of it...

I use 3 to apply wax. Use 5-6 for polish. Not sure about the model.

So you think speed 3 won't be enough to polish ?

3 probably wont be enough. Using a PCXP I generally polish at speeds of between 4.5-6 and then slow down and jewel the finish at speed 3 or 4. I do have a GG but haven't used it but have heard that one should use it at least 1 speed slower than you do with the PC. Every car's clear coat is a little bit different so it just depends on the car. Some cars may have soft clears and speed 3 may work just fine for them. Other cars may take a speed 4 or 5 on a Makita rotary to do the trick. Nothing quite nerve wracking as polishing out a $150k vehicle on speed 5 with a rotary! Plus the type of pad you are using and its cutting abilities along with the compound or polish you decide also plays a big part of your speed selection. One last thing, are you trying to remove scratches and swirl marks or just restore gloss? If you need to do paint correction that will require more speed typically. So with all that said, what is the year and make of the car you are working on and what's your goal here- to achieve paint correction or just restore gloss?

I think you'll need to higher.

Well, actually just to remove fine swirls from my car it's a VW Gol (Brazilian model, it's like a cheaper Golf)....
But I gave up the idea... I realized that it makes too much noise above speed 2 when touching the hood.... so I think it wouldn't be nice to do that in a sunday.... during the week I guess there won't be any trouble to bump speed to 5 or 6...

I did a square test section on speed 4.5 and it worked fine with Meg's ULT Polish... anyway... this was my first ride doing this and I still have to learn to calibrate downward pressure and refine the movement pattern.... I realized that you don't have to do almost any pressure or the pad will stop rotating....
Funny how things are different when you do although I have already watched tons of videos about polishing....

Some pics...
Before 1st pass...

After 1st pass...

50/50 after 1st pass..

After 2nd pass..

Trying to get a comparison between test section and adjacent...

Well it's pretty hard to see differences in red (that's pretty much well cared, but did saw many swirl washes already, but not anymore) and not under the sun... this camera also clips red pretty hard, so I did my best to deliver some reasonable pics...

You are correct as you have experienced that when you apply too much pressure the pad will stop rotating with a DA. You only need to apply about 15 lbs of pressure for paint correction when using a DA. One way to learn how to calibrate this is to take your DA machine and put it on a scale like you weigh yourself with in the bathroom. Then put your hands over it like your polishing and apply downward pressure until the scale indicates an extra 15 lbs beyond the weight of the machine.

Nice tip! I Just did that I guess I'll practice from time to time over the scale... :xyxthumbs:

Speed 5 with foam pads, speed 4 with MF pads. This would be for correction.

Thanks for the tip! Right now I'm using LC Hydro-Tech Kompressor pads, but I did bought a MF kit in this week VIP's because everybody says it is so good.

I really think Kompressor pads are best suited for a rotary polisher. Next time, buy flat foam pads for your DA. :dblthumb2:

The MF system is GREAT!!!

Why ? Does kompressor pads need a more powerful tool ?

I also took the Yellow CCS pad bogo.

It's the design of the Kompressor pad, not the power of a tool.

LC Yellow pads are pretty aggressive and will leave behind marring/haze on the paint. You will have to follow with a finer pad and polish.

Yeah... that's the idea... I bought it for the tough work

There's really no need for the yellow pad if you bought the MF system. The MF cutting pad will cut and finish better than an LC yellow pad.

Well it does is on bogo... so I think it wouldn't harm to have.... and I think it's good to have some spare in case I came across a really bad paint, with clear coat failure and don't want to mess with my MF pads....

You're better off getting the Surbuf pads than the yellow ones. The Surbuf when used properly on some clear coats have more correction ability than the MF pads. Plus the Surbuf lasts longer and cleans alot quicker and easier than the foam pads too. If I had the money to do it, I'd have about 4-6 pads for each of my preferred pad colors and then about 10-15 Surbuf pads.

Why so much concern about the noise? If you're only doing your car on one day, for an hour or so, I wouldn't think it would be thought of as any different than someone cutting grass or some other routine residential chore.

That's a lot of pads.... LoL....
I'm just starting it.... I'm yet to do my first car because of the lack of place to do it... so I just take it slow for now...
I just got the yellow because it was on bogo or else I wouldn't....

Well.... because I live in a apartment building... so even though I'm doing it in the garage, the noise can propagate to some apartments and it will be pretty loud inside the garage....
Hell! I can't even use the power outlet from the garage..... but I use it anyway... :dblthumb2:
