Quoted from terryb:Hey lladnip, I could be wrong, but I presume the engineer's at Novus understand abrasives fairly well. That is why when I called I specifically talked to an engineer rather than a customer service rep.
Wood is a whole lot softer than a lacquered or clear-coated playfield. So you really can't compare the two. Use some 1200 grit sandpaper on wood and use it on stainless steel and you will find very different results. That doesn't mean the abrasive rating is wrong, just that you're using it on materials with different hardness ratings.
My original post was not intended to start an argument about how abrasive Novus is, but to remind people that it is abrasive, which most pinballers don't seem to understand. It is a polish, not a cleaner.
As markmon said better than I did, why use an abrasive when you don't need to.
in my personal exp- being wood fab, metal fab, glass work, or painting and clearingcoating surfaces sometimes automotive sometimes pinball playfeilds i can only state they dont have the same cutting action.
dont misunderstand me- i love novus products, 1 2 &3 have them in the shop and find there preformance to be very good, and tend to be fond of 3m for sandpappers for that matter and i tend to go to at least 3k to 5k befor i ever switch to rubbing compounds.
material removal process is fairly complicated for being so simple, and involves a few varibles such as substrait traits of whats being being cut, the cutters harness, size, angle or cutting work edge, matrix suportng this work angle, force being applied, and efficient removial of cut matreial to get it out of the way so you can get a fresh bite at new material......
anyways- im my opinion they are apples and coconuts, and i dont think should be stated it's
" x-it like useing x grit sandpaper" well because its not. its an over simplication. i dont care if its an engineer giving the advice- if i wantted my playfeild clearcoated and polished out i would not go to an engineer.
(boreing side note- at the nuke station ive done some work at it has been an ongoing proublem in the past where somebody changed protocal and voilated procedual use and damaged plant equiptment as just being told something, even by engineers- as such were under directive to stop work and the procedual must be offically admended befor we can mod an item)
everbody can be missinformed its ok its how we learn
