I was grinding the rust out of my longs, when I got the notion to keep going. Has anyone done this with decent results? The hypothesis would be that a brass cup would generate less heat than a sanding disk. Any thoughts.
I should also state that my homebuilt air compressor is a little on the whimpy side. Quincy pump 3.8 scfm @ 100 psi. (probably not enough to run a d/a) Thoughts and criticism (on the idea) are welcome. thanks bryan. This is my second post. Please be patient. |

Not a good idea... you'll have so many deep scratches it will kill the body.
If you do not think you compressor is up to running a DA then purchase a inexpensive (read not cheapy) electric orbital sander with a soft hook and loop pad. You can usually get a 6 inch pad. Use AUTOMOTIVE sandpaper, hook and loop style. I recommend Norton papers as they are my brand of choice. |

DON"T USE A GRINDING DISK!!!!
I think you're talking about a wire brush, which would be ok as long as you don't get the metal too hot. I prefer using a large DA (~10") and course paper (36-80 grit) to do the initial removal, followed by a finish with less course paper until you are down to bare metal. Matt |

i used the grinder (with a wire brush) a lot when i was working over my engine compartment and my rocker panels. along with aircraft stripper, por products and god knows what else.
i can't say the grinder was better for me, but it sure was faster! anywhere i thought was critical, i sanded afterwards for a better look. i wasn't doing a concourse job though and i had little patience for the project after a while... still, it turned out pretty good. |

Eastwood has a brillow pad type paint stripper (probably a 3M or notron product) that goes on a RA grinder. Supposedly works well.

QUOTE Eastwood has a brillow pad type paint stripper (probably a 3M or notron product) yes you can get these to mount on air or electric grinders. Use a coarse Scotch-brite type disc, theses dont load up with paint and goo, dont impart alot of heat into the parts, and last pretty long. That compressor is wimpy for driving constant duty air tools. This is an example of a suitable disc |

Sorry to post and run, I got called in to work. 914 q.t. cut short. (so sad) Anyway thanks to all who replied. Sounds like the random orbit is the way to go. I may wind up doing a culmination of scotch bright, wire wheel, and r/o. Did i mention that the previous owner forgot to use primer....excluding the trunks. thanks again for the insight. Experience outweighs opinion everytime. -b |

You only thought it was a day and a half because of the fumes. You were really out there for a week. (IMG:style_emoticons/default/lol2.gif) J/K
