| I only use a rotary, I feel it delivers the best results in the shortest amount of time. As for usage my words of advice would be to keep it moving and keep it flat follow that and you should be okay. You don't need to crank up the RPM to grinder speeds, 1,000 - 1,200 has always worked well for me.
can you screw up a paint job fast with a rotary? yes! spend 1-2 hours here reading the posts about rotary usage and you should have developed a good mental library on what "not" to do or how not to use a rotary then give her a try. also, take your time at first, hurry it up and you'll screw it up. |
