lingering emery and white spots

[eyekandi]

I've been running into this alot lately on my truck polishing i'll have streaks that appears to be my rouge left behind when i use a sisal wheel to beging removeal of corrision and some pitting. i change directions to remove it but it stays. i'm using a hand buffer spinning 3250 with and 8' wheel any ideas? Then on another note i've been running into white spots i do some light sanding to smooth things up a little and no matter how hard i try with the wheel it seems to stay, is this because alot of truck washes use acid and it has really ate into it?

Usually when the compound sticks, I find it's either due to not enough heat while buffing, or I haven't spent enough time with the last step. Seems the compound wants to stick in the micro scratches.

Perhaps you need to do some sanding before the emery...?

The white spots - may be just due to the fact that you're doing spot sanding, and those spots are going to look different from the surrounding areas. What grit(s) do you use?

ditto on what mike said. also i agree you should at least sand once all over. you can sand the scratches out and work them down then final wet sand the whole part with at least 600 grit before you start to wheel it with the emory.
