While it works.. emory paper or boards are super harsh on a points surface.. they leave shards that gouge the metal on a microscopic level, further reducing contact area, and making micro high current spots that actually encourage future burning. that said.. yeah.. I've done it before. when i do.. i use 1000 or 2000 paper. don't take much.. and I only do it for the most coroded points. i then pull clean white typing paper or brown paper bag thru them..or maybee with a drop of rubbing alcohol on them.
that's actually my prefered method to clean points.. stiff coarse paper.. like grocery bag, 20# typing paper.. construction paper.. etc. lets you see what you pull off.. and is an abrasive paper when it gets right down to it... if you've ever seen the surface of aper under an electron microscope it looks like a ridges rough surface strewn with fibers... cleans points good.
my 2nd favorite points cleaner, after coarse paper is a proper fine toothed ignition hone. in plain terms.. it's a file.. but it is exceedingly fine. trick is to slide it inbetween the contacts perfectly square and only a time or two.. you really want to leav ethe surface metal ( tungsten or other ) intact and not get into the base metal.. once you get the contact metal wore thru.. the base metal erodes pretty quick... that said.. i usualy get 4+ years out of points starting by paper cleaning.. then perhaps a honeing after a few.. and then after a few more.. the sand paper.. generally after 1-2 sandings and a few years.. it needs points.. I think I've been able to get 8yrs on my longest run set of points so far..
for mags, try to get everything perfect... fouled plugs are troublesome for mags,, kep the plugs cleaned or new ( I like the sandblast cleaners.. just remember to get the abrasive media completely of fthe plg with air... then a shot of carb cleaner.. then a dollar [edit])

AGREE. Show em some money! Unless there is real damage this will work best due linen content.If I let my Farmall Cub sit for a few months the points get a little cruddy. It doesn't take much to clean them up. Usually just pull a piece of paper through them. A dollar bill woks nice.
