What causes buffer marks?

[wizardofahs]

Besides the obvious... a buffer?



I used my rotary for the first time last night and this came to me... there's all kinds of info here on what the marks are and how to get rid of them.... but what is it exactly that causes them?



Is it a buffer going at too high speed? To fast over the paint? Too much product? Not enough product? I don't see any buffer marks on what I did with mine (haven't gotten it in good light yet though) but I want to know what I need to do/not do to prevent them.

Buffer marks are caused by a too agressive pad, product, or a combination of both. Holding and moving the buffer at a really high angle. HAving the buffer bounce/skip the surface. Having a dry pad or unprimed pad. Having paint that is too soft/fresh. And like you said a buffer mark and BURNED paint can be attained by having the buffer at too high of a speed and combined with the wrong products and pad.



There are a lot of things that cause buffer marks, but I find that someone using the PC or the like for a while and reading a lot about rotary buffers seem to have less of a chance of having buffer marks over someone just picking up a buffer and going at it (no prior experience with a buffer.)
