PC in tight quarters

What do you guys do when you are running your PC and need to get into a tight spot, or work up to an abrupt contour, or deeply recessed area that is not wide enough for the entire pad?
 
You can't get away with feathering or tilting the machine on a PC as much as you can on a rotary. Although I do tilt my RO from time to time to polish narrow areas like rear pillars and rocker panels (if my back doesn't hurt!). In some instances wherein the area is simply too tight, I make do with hand polishing.
 
I'm not sure if this is "proper" or not, but I was surprised to find that a lot of contours (that are convex, not concave) could be done by PC. I just thought "what the heck" and PC'd those areas with only partial pad contact. It seems to be okay. :nixweiss For example, I did some bumper surfaces and the door pillars (trim masked off of course).
 
Yep, go ahead and just do whatever's necessary or do it by hand. As jduarte said, it won't be as effective as with a rotary (edge-use of which might be TOO effective if you're not careful!), but it'll work. Using the new, larger pads gives you more edge to work with. The PC is still SO mild that the concentrated area of contact isn't a problem. But often it's at least as easy to just do those kind of spots by hand.

For really tiny areas (like around the keyholes, or little areas in the engine), how 'bout a Dremel tool?

Be VERY VERY CAREFUL using a Dremel on paint. Remember that it's a "mini rotary" and that all it's power will be concentrated on a VERY limited/small area of contact. No way *I'D* try that.



I still just do the really tight areas by hand when I need to, which isn't all that often.



Russ968- Using the 4" setup on the PC isn't the problem-solver that people expect (I tried it AGES ago when using a DA primarily for bodywork-related sanding). IMO, it's better to use the edge of a bigger pad.

Thanks for the warning, Accumulator. I thought I had heard the Dremel was a useful tool in those instances. If you wouldn't try it, though, then neither will I! :cool:
