If they are tiny, I have had good luck with Finnesse It. It is a 3M product. I think LMI sells it if you can't find it locally.

Which Menzerna compounds did you use the cans of paste or the dry 3-pound bars?

Lance, the Maguire's polishing compounds work well. I think it is the number 7 that's used for this. I got the tip from Mario a year or 2 ago.

You can also find them locally, which is a plus.

I used the 3 bars from Grizzly - and Brock _ tried the fennissit it 1 2 and the glazing compound - and it gives it a blush look.
Ill stop and get some Maguires today.

Thanks Guys.

Lance,
Unless the area is just too big...I always use the Micro Mesh on Nitro repairs. Take it up to 12K and it should be like new...no marks!

If I have one that blushes or hazes I have followed that up with a water/soap buffing.

micromesh 12,000 is way coarser than any polishing compound. If Meguiar's #7 won't get it out, start with #9.

You positive this is nitro, and not polyester? Nitro's a breeze to buff.

This repari started out with 6 spots where the PLASTIC bindings had pulled away from the sides, both at the waist and in the cut away. I tacked each spot down with CA, and after sanding and leveling - and appying the nitro - all the spots have seemly come together on the back side, they just kept growing - so ive buffed the entire back out, the side areas were kept smaller.

Lance:
Are you using 3 SEPARATE and CLEAN buffing wheels? If not then you will have marks because the coarser compounds are still impregnated in the buffs.

My last Menzurna compound is "Very Fine" and I have never had any marks in nitro with it. I follow up with McGuires #7 for a slippery and shiny surface.

Lance, scratch head, beat against wall if required, re-think plan of attack. I think chances are somewhere between polishing grits all the scratches from the previous grit were not removed or you started too fine. If you go too fine too soon the deeper scratches just won't go away. I have a shelf full of buffing compounds and polishes to prove this hard learned lesson. Also what others said, clean buffing wheels, polishing cloths, and lots of compressed air and cleaning before the next grit. Good luck.

You can get it through aout supply retailers. I apply with felt pad on a 1" sq. block, one for each paste. I use vigorus padding motion then buff off with a small 4000 rpm auto buffer with a lams wool cover also a differnt cover for each paste.

Lance,
are you still sealing using Z-poxy? Spraying Nitro over the Z?

I seem to remember Mario posting something about reverse sanding to remove deep scratches. Does this apply here?
