At work I use the 3m range of compounds after flated or nibbed a panel I go to polish up with either fast cut plus or xl but can never seem to be able to get rid of the marring and scratches that it leaves even following up with there yellow top and pads they don't shift I make sure the pads I use are clean And try different work times with the compound to break it down is there a trick to this compound or is there an alternative to use as a follow up to this step because it is frustrating to see the scratches it leaves behind any help thx:thumb:

Probably either not working it fast enough or not long enough or not enough pressure I'd of thought. How long have you been working it for?

Are you using their green pad with it?

It's been a long time since I used the 3M range.

I used to add a little ultrafina to fast cut plus to increase work time. Its oily nature really helped for me.

1800-2000 RPM was my preferred speed range for fast cut plus


As above I'd say cutting sets short is probably the culprit

Make sure the pads are flat too. I see lotsof people on rotory angling pads for flat surfaces which is going to cause trails and holograms every time. I think you should hit it with Blue Top as that is their recommended finishing polish. I didn't know any of the other 3M compounds could finish down perfect other then Ultrafina, althought I haven't used any of them.
