Sanding vs. Wool

I'm in the middle of another project and just shot the last of my paint. I was picking up supplies and saw some 0000 wool next to the tack cloth so I picked some up. I have never used wool before so I'm wondering what are the pros and cons of wool vs. wet sanding and which is prefered. Also when is it okay to use wool? Is it good for the final paint sanding before clear or just after clear is done? Thanks jemsters!

Re: Sanding vs. Wool

Steel wool should never be used on paint you're intending to polish, at any stage of the job.

Re: Sanding vs. Wool

I have used 000 and 0000 wool between coats of polyurethane clear coats with great results. I cannot comment on paint, stick with rich's recommendations, as he's usually right. If you start working with poly clearcoats, steel wool is less messy, lasts longer, and conforms to the guitar's curves better than sandpaper for roughing in between coats (i've found). I've been warned away from steel wool with waterbased products, though.

Thanks! very helpful, I will try that. What about for the final sanding? should I stick with wetsanding up to the end? Thats what I usually do.

Re: Sanding vs. Wool

I've used it on doors between coats, but if you want a gloss finish I'd never use it on guitar paint. There is no control over the depth of scratching with steel wool, where sandpaper has a constant grit.

Re: Sanding vs. Wool

You should also know that ANY traces of the steel wool left behind WILL oxidize.... in other words RUST under your clear. Stick to wet-sanding.....using an automotive sanding sponge will get you around any contours nicely.

Re: Sanding vs. Wool

To reiterate what rich has said... do NOT use steel wool on paint. DO NOT. Ive used almost every method possible to finish clear coats. Steel wool does NOT work.

Right now, Im using polyester, urethane, and enamels to clear. Wet sanding works. Why tempt fate with steel wool?

that said, nothing replicates steel wool over an oil finish (i.e. your neck! )

edit : 600/800/1000 wet sand, then buff with scratch and haze remover. Polish with a good polish.

good to know. I will be using true oil on the neck so I could use wool on that, plus I have some dirty pots and pans I need to wash. lol
geez, I've been wet sanding up to 2000,, an I obsessing?

Re: Sanding vs. Wool

I finished the final paint sanding with...a trusty sanding sponge!!!, one of the thick ones with the angled edge. Jesus. I've had this thing sitting around for years and finally it hits me to try it. I won't be going back to sandpaper ever again.. (except for the clear coat) The sponge did it all, even the edges, with no sand-through and everything turned out super even..

Re: Sanding vs. Wool

so much hating on the steel wool A word of caution on those sanding sponges or nylon abrasive pads. I bought some from a local hardware store, red was medium and blue was fine. Red did a nice job, but blue rubbed blue streaks into the finish that were difficult to get out. I can't remember the brand, but they were NOT 3M. I switched to steel wool and didn't have this problem.

By the way, that paint job looks great and we are looking forward to the finished guitar

Re: Sanding vs. Wool

Thanks,
Seems like 3M products are the way to go. The headquarters(its like a little town) is literally a few blocks from my house! I tried to get a job there years back but they were not hiring at the time.
