I recently got introduced to these Poly clean & strip discs, They are so very useful and work brilliantly, so far i have used them for removing mill scale of black steel, one wipe and its gone, also they are great at cleaning gasket surfaces as they remove everything but don't damage or remove any of the steel. They also remove rust down to clean metal.
Also great for removing paint.

Oh yeah - 3m and Norton have a couple of different grades. I don't use them on aluminum as they will gouge soft metals, i.e. intakes
They are also great for also removing several layers of skin for the careless.
I have but do not like how fast they wear.
Yup,,I use the spindle mount ones on an electric drill,,wear them down to almost nothing..Good for getting into tighter places..
after stripping a 55 chevy with the large ones i invested in the blasting setup. :) wore me out but they do work well. i do like using them to clean up after blasting . less time than a da and 80 grit. they will get rid of flash rust quickly .
I have been using them to get into tight spots after I acid wash scaly parts,along with another neat little tool that has inch long rubber prickles/spines.It doesnt take long to rip the rust scales out..Quote:

Used the drill mount 3m varieties on removing most of the paint and rust off my fenders. They do work great, but with the drill mount they wear your arms out, and will take off across the project it your not real alert! I would love an angle grinder version!
stopped using chemstrip in the early 80's . since then it's been razor blades and scotchdisc . now days i just fire up the diesel and blast away. :)
they been out about 18 years used them in the body shops i worked at we called them rice cakes . used them mosty on a hand drills. speed is the trick to getting them to last along time just like sand paper on a D.A and other tools no more RPM then it,s needs to keep cutting any more your just burning them up
I have one for my drill motor and it does seem to strip somewhat faster.Thing is the drill doesn't seem to have the guts.So I went out tonight and bought two from HP for my 4 1/2 grinder.Costs me $20.00.
We must be gettin' old, Shine!!!! Faster ain't always better........Quote:

I still like my DA and a stack of brand new 80 grit discs. Also becomes a very good time to thoroughly inspect the sheet metal and mark all the spots that are going to need attention. Media blasting is good, great for frames, suspension pieces, inside body braces, etc. but I'll stick with my DA to do the skin work.....
the last car i striped was a 63 caddy 4 door over 18 feet long of fun .i did dry strip many cars and trucks at the shops i work at many were Gm delamination but not many as big as this boat less sand paper and work. tape off joints lay paper on the floor keep the striper wet till it,s working up paint clean off with a body filler spreader brush more on till metal is allmost clean use a red 3m pad and lacquer wash dry .no damn sand or beating the guts out of the air compressor . i did a vett that some bone head use a steel house scraper on he could not tell the paint from the SMC i had alot of time getting it back were it would take primer
i can peel one in a day or so with my blasting rig. no damage to sheet metal. i have a media for paint, one for rust . i can blast fiberglass also. but i run my rig at 30-35 lbs of air . depending on the car i still use the heat gun / razor blade on many . peel them down to primer then clean up in the blast room .
dave, i can tell how old i am now every time i pick up that 1 1/4 hose . damn thing will wear you out .
Man Shine-what size compressor do you have??. Huge CFM??. Air respirator??.
185 cfm diesel powered compressor . 6 cu ft hopper. i wear a blast suit with a nova6000 air supplied hood .
My blaster pal Paul has a huge rig like that, travels and does a lot of stationary equipment and State equipment in their yards.... He'll swear up and down that hose only weighed half that much when he was 30!!!!!Quote:

Paul's the same way with blasting, given time to set the machine up, think he could blast the skin off an apple!!!
Well I tried the disc's and confirmed to do a decent job stripping,but don't last very long.I'm going to upload some pictures of my rust repair tonight on my rust repair thread.
speed is key on them the cheaper clean strip wheels have a stamped arbor were if to much rpm you can spin the center out or wear them out .we pick them up by the pack and pick up a arbor or i made them up were i would run two at one time buy stacking them 3m and dog brand were the ones i usedQuote:
