All I use now. I tossed all my other clean up and grinding disks. Only cut off wheels and flapper discs. HF will run specials and sell the 60G in packs of 3 for 5 bucks or so. The name brand ones are better and last longer, but they are not 450% better.

I bought only one flapdisc, just to try. It for sure was fast, but loaded up as 243 mentioned. I'll pick up some coarse grit today. This frame is in good shape as I have already cleaned it up once. I am redoing it now because of incorrect prep work previously. I wear a dust mask, especially with the flapdisc. Thanks everybody for your input. This has been a big help.

Scott,

I would not use flap discs for the initial material removal on the frame, it will take forever!

Use the wire wheels and go back over it with a course flap disc.

243- Thanks. I agree with you. I figured it out with OJT!! I'll stop posting in this thread and continue in my Bedliner for Frame Paint thread, so as not to duplicate. Your advice on the 36 grit was spot-on! Got three of them!!

Might also consider shooting the old finish with "Aircraft Stripper".. paint stripper. It comes in both brush on and aerosol cans. Shoot it on, let it sit a few minutes (don't let it dry) and then scrape it off with a putty knife. It will blister most finishes almost immedieately (including powder coating) and slough off really easy. Scrape large areas, then come back over with that knotted wire cup.

Should be able to easily strip an entire frame to bare metal in about 1 day.

Keep in mind that paint stripper is harsh. Eye protection, chemical gloves, respirator and a tarp (to collect the junk that falls off) are the order of the day.

Thanks, BESRK. Even with the new abrasives this is still a tough job. I have some on the shelf in the garage. We'll try that tomorrow evening.

The flapdisc flat doesn't play! Pick up the grit that you want and you can rock-n-roll. Another option that would work very well is a sanding disc on a grinder. Check out the thread Bedliner for Frame Paint... I have a picture of the sanding disc I used. Someone mentioned earlier about using a mask... either of these methods will create copious amounts of dust, so be sure to have something handy.
