m105 then 205 and then?

[jackychai]

recently i have switched to m150 and 205 combo, results are great but there are still a little bit of swirls left, should I use menzerna 4000 to follow up or 4500? or any other suggestion?

thanks.

Before you add a third step in this maybe you can refine your process a bit with the meg's twins. What machine and pads are you using?

[tuscarora dave]

What type of swirls are still present? Are they buffer swirls from a rotary, spider web type scratches not removed in the compounding stage, or a haze of sorts left behind? How often are you cleaning your pad while finishing with 205?

You can work surgically clean as far as dirt and dust goes but if you are allowing a build up of abraded off paint and spent abrasives on the pad, this can leave some very light marring.

Perfect answer Dave....


SF 4000 would be a good choice as it has a little more cut and still finished down show car quality. If you're into doing show car work get both.

thanks for the info. i have got some inspiration there.

i am using rotary deWalt 849 with . lake county orange with 105 and white with 205.

cleane/squeeze/rinse/dry like 4-5 times on each combo for a small car. i have tried different pressure even sometimes with yellow pad with 105.

but anyway i will try again with more cleaning in between and maybe a bit more pressure.

how come the 4500 is so much cheaper than 4000? i just can't figure out why the menzerna has so irregular price on polish.

I'm going to give you my guess as to why SF4000 is more expensive than SF4500.

Having used PO85RD both with a rotary and a DA polisher, it is clear to me that this polish contains a diminishing abrasive that has a unique set of qualities.

1. The abrasives seem to be quite harder than most DAT finishing polishes. It takes longer to break down than a lot of other DAT polishes, suggesting that the abrasives are harder.

2. A lot of your cheaper DAT finishing polishes seem to have the occasional "not so finely milled" pieces of abrasives in them that cause tic marks or fine scratches in an otherwise nice finish. PO85RD doesn't have these stray, inconsistent pieces of frustrating oversized grit. (Could even be dirt, who knows?) SF 4500 "with the extra work of breaking down the abrasives" finishes out absolutely flawless with the right technique.

I have yet to use SF 4000, so this is the guessing part of my reply. From reading the description of SF4000, it seems to be a non-diminishing (SMAT) type of abrasive that would be not only harder than the abrasives found in SF 4500 but knowing something about Menzerna's high quality, the abrasives are likely to be just as finely milled, if not more finely milled than the abrasives in SF 4500. If this is the case then it would be safe to say that it would be a product that finishes down just as fine, but without the need for the special, learned technique involved in breaking down the abrasives.

This would provide the end user with a means to produce a flawless finish in less time. I'm sure that this was their intention in the designing phase of creating this product. "To make finishing more efficient at the MB factory" I'm sure the "You get what you pay for" concept applies to this product. Not to mention that it likely costs more money for the formulators to use these SMAT abrasives and to mill them finer and more consistent in size than what most of the other formulators in the industry do.

If anyone can set any of my theories straight, please do.
