    Abrasive HELP

    In the General forum there have been some questions regarding abrasives. I though I'd post over here in the finishing section and see if anyone has any good advice.

    1. What brand & where do you buy 5" & 6" ROS abrasive pads used for polishing or rubbing out a finish? I'm talking about the series of finer & finer grits and finally buffing pads used with car polish.

    2. If anyone has experience using water based finishes like Target USL etc...what type of sandpaper do you use. Looking for quality first, price second.

    Thanks
    John Whittaker

    If you're referring to the MicroMesh type paper, I've bought from these folks before and gotten good service.

    3-M has great products... The Trizac and Micron discs are great for going to a polish. Mirka's Abralon is excellent as you get past 400 grit, and can be used dry or wet. I also like their Abranet products (no hole pattern necessary since it is a mesh) for normal ROS. A little more expensive, but doesn't clog. For bang for buck, I stock alot of Klingspor products. Many great buffing compounds out there -- 3-M marine paste, Farcala water based G systems. Are you polishing a woodend substrate with finish, or a solid surface like Avonite, Corian, or some form of stone?

    John and I both are going to use some Target water based finishes and need stearate free products for these projects. Any information along these lines as well as answers to Johns origional questions would be of great value also.

    John, I've sprayed about 6.5 gallons of Target USL and had good results with this "rubbing out" routine.

    Spray 3 light and 2 heavier coats of USL lightly sanding between the 4th and 5th coats with 3M 400 grit paper (dry sanding). If you find a bunch of bumpies on the first couple coats, burlap will knock them down pretty quick. Use a damp towel to clean any dust off the piece.

    Let the piece cure for a week or more.

    Sand the final coat with 3M 600 grit wet/dry paper using water. Sand just enough to knock the nibs down and get a even scratch pattern on the piece.

    I then get out the RO Polisher (PC 7424 is what i have) and the Meguiars Fine Cut Cleaner and give it a good going over. This should give you nice satin finish that can be further shined up with Meguiars Machine Glaze or polish if you wish. Final polishing is by hand using Renaissance Wax. The wax and polish i get from Highland Hardware.

    The big thing is to let the finish cure for at least a week or you'll find it difficult to get a consistent sheen.

    I'm no Flexner so I'm sure there are better or faster processes but I've had good luck doing it this way. YMMV

    Hi Brian

    Glad you are here and thanks for the info. This is exactly the type of polishing/finishing I'm looking for. (Allen too I bet)

    Is the P/C 7424 a polisher only or is it the one that can also be used as an ROS?

    I use USL all the time. I have a Festool Rotex Sander. First I sand with there Platin 500 grit. The switch to Menzenra compounds. with a Hard felt pad. It's sold though Traget Coatings website. Mostly the DD3, And 2L. Between coats I use Festool's Brilliant abrasive 400 Grit, It's Stearate free. With my 150/3 but for the most part after the first coat isn't necessary.

    John, Thanks for the Welcome!!

    The 7424 is sold as a 6" RO Polisher. I comes with a stiff Hook and Loop pad and a polishing pad but I'm sure to would perform well as a sander, albeit with no dust collection hook up. I envision using it with some 60 grit paper for shaping a chair set but with no DC......

    Here's a quote from Amazons discription.... The way itís designed, most people will be able to control the tool with one hand, whether itís being used as a polisher or as its original purpose, a random-orbit sander.

    I used to use a 12" Craftsman Polisher and found the 12" pad did good on large open surfaces like a table top but became all but useless when working on installed shelves and such. The 6" pad on the PC fits much better and still does a good job on the large areas.

    Although I haven't tried them yet, somebody (Lee Valley????) sells H&L polishing pads for a standard ROS. It may be a cheaper option than the $120+ PC, however, i also use it on my truck and the LOML's car. (Hmmm shouldn't that be the other way around????? She uses it on my truck and her car??)

    Make sure you show us how your finish turns out!
