I have used the rubber discs on numerous mating surfaces over the years and not once has it resulted in a leak with the use of the CORRECT wheel. Use the incorrect wheel for the material and all bets are off.
Some automotive manufacturer's do not support the use of these pads due to the fact that the bristles may get into the oil supply and cause issues. Common sense should be used as to not hold it in any one place for too long.
At the same time I have seen just as much damage caused by people using a razor blade incorrectly on an aluminum surface. Visible gouges where the blade digs into the surface. Again, use common sense and all will be fine. Joe

Someone with minimal training can use a razor blade and not leave even a slight imperfection on a gasket surface.
Granted, a "hack" can ruin almost anything.
Certainly, we could do jobs much quicker (an thus make more money) by using the same tools and techniques that "flat rate" mechanics use.
I personally know several of these guys that don't even own a torque wrench.....they are very good with an impact.
I do very **** custom work....for the same prices that the flat rate guys charge prices.....and my statement stands. Use a 90 degree grinder on an aluminum surface with any kind of gasket removal pad (at my shop) and you will be "out the door"....as fast as the office can process the paperwork.
People are free to choose who to have work on their 928.....however, you would be stunned at how many jobs I have to redo...from other shops.

Plastic razor blades. Will not gouge aluminum, will get most gasket material off.

Worked for me on my WP. Beyond that I defer to your superior knowledge and experience.
Another possibility is that you have both on hand and use the steel blade if the other fails. Steel will gouge unless you are scraping with the blade perpendicular or shaving with the flat side of the blade against the sealing surface.

Thanks Everyone!
I'm going to hunt down some Permatex. I'm with Greg on this one...power tools on sealing surfaces....freehand...can't be a good idea. On my old GMC maybe...but not on an Alusil or aluminum block.

“It's unwise to pay too much, but it's worse to pay too little. When
you pay too much, you lose a little money - that's all. When you pay
too little, you sometimes lose everything, because the thing you
bought was incapable of doing the thing it was bought to do. The
common law of business balance prohibits paying a little and getting a
lot - it can't be done. If you deal with the lowest bidder, it is well
to add something for the risk you run, and if you do that you will
have enough to pay for something better.”

On that topic, Ive had this quote pinned on my office noticeboard for decades, still applies today ... and I too get many calls from those who've dealt with the lowest bidder and been burnt. These days I'm less sympathetic.
