Hi; I am looking for opinions on the finishes that you see in some type of boards. I remember some 15 years ago all those HP boards with the 400 grit “parallel” sand finish gloss
but I do not think that several boards that I have been seeing lately sport that kind of grit finish.
Looks like the polisher rub out the gloss then the desired part is sanded with a 3M sponge? because I do not see those parallel marks more like swirls and completelly matte.
Wet sand to 320, then Scotchbrite pad maroon (fine) or grey (ultrafine). That’s what I do.
Just my 2c…
well; 320 is what most of the crew use to start polishing the gloss so then a fine pad cannot get rid of the 320 marks.
You mention maroon but I think that you are referring to the Purple one that seems like 500 grit
That’s cool Stoney! Never had seen that chart. Good info. Mahalo
…however; I have here two or at least one 3M pad that are not there. One is the Purple but I accept that for some colour blind persons Maroon in could be Purple but Also they sell the Green one that is a coarser grit. I have it but I never used it for this application.
What I obtained with the supposed maroon/purple is: after 320 cannot let a nice finish; then if you use it like in many shops after the gloss polish I obtain a matte finish but somewhat bright yet not like those boards mentioned.
I buy the cheap coarse Green ones and use them for a variety of things. Cleaning paint buckets, getting adhesive off surfboard left by traction pads and washing dishes. By the time you’ve scrubbed your cast iron skillet with it a few hundred times, they are nice and soft. Not as coarse. I use the Grey pads for burnishing wipe on finish.(ie “Secret Sauce”). Indasa also makes the Grey and Maroon pads. As good or better and cheaper than 3M.
