Which Meguires product, the ultimate compound or something out of the professional line?
I have Meg's 101, 105, & 205 plus the ultimate compound. I find for hand stuff and small patches the U/C works pretty good. Now the 101---------------OH BABY! I love that stuff then follow it with 205 and a very soft pad= ooooooooooooo shiny. The pro line is a bit pricey for a bike, but it is a sickness of mine LOL.
If you used the Meg's pro line stuff there is a little coarseness label on the bottle, you want to finish up with nothing higher than a 4.
Hope that helps.
