Sonus Scratch Removal Kit PC Counterweight Conundrum

**D3mon** · 05-03-2006, 05:16 AM

Yay! my Sonus scratch removal kit arrived in the posts this week.

I`ve not tried to attached it to my PC yet, but I`m thinking I might need to mess around with the counterweight?

I`ve been using my PC quite happily so far with the Sonus DAS polisher Kit (6-7inch pads?) so I assume the counterweight is currently fitted (can`t remember now)

We have had many counterweight discussions here. The 7224 PC comes with a 5" counterweight, while the 7336 comes with a 6". There are some who feel the counterweight makes no difference. Others of us (myself included) contend that the 6" weight makes the PC smoother at high speeds (6). I think most of us who use the 6" counterweight just leave it on, even when we are using 4" pads, it doesn`t seem to negatively affect anything.

Thanks Mike. Good to know I wouldn`t have broken anything if I`d been lazy! All I`ve got to do now is find the wrenchy thing to change the backing plate...

I just bought a 7424, and FWIW my understanding is it is now shipping with the 6" counterweight. My PC in a kit came with the 6" counterweight installed.

Didn`t get the PC there, but this info came from the excellent info page at Coastal Tools (look on bottom of page):

I`m finding this waay hard work. The sonus scratch remover `feels` kinda weak as it seems to take so much effort for small improvement! Is it my technique?

I`ve spritzed the 4" pad, put on a `cross` of scratch remover and gone in on a setting of 3 on the PC to distribute the polish (at medium pressure). As the polish seems to get nicely spread, I move up to 5.5 or 6 on the PC dial and work it in (with good pressure). I`ve made two passes like this, but the swirls are only about 60% gone? The car is a ford, so I wonder if the paint is particularly hard?

I haven`t tried the Sonus stuff so I don`t know what you oughta expect.

It *does* sound pretty mild.. but for two passes to remove 60% isn`t all *that* bad. If you use a more aggressive product you`ll have to be more careful and you might have to do more than one step to get a ready-to-wax finish.

FWIW, I don`t spritz my pads, but rather I distrubute the polish uniformly and prime them that way.

IIRC Ford clear is considered kinda soft...so I *am* a little surprised the 4" setup doesn`t correct it faster. But there are worse things than using a safe and mild product/pad combo a few times.
