I got mine at rc. It's a 3 step system, but I forgot what it's called exactly. But if u go in and talk to skip he will walk u thru the steps, u do have to buff in certain directions yo get good results.
Novus for fine straches...for deeper straches, determine if you need a sand paper type fabric. run your nails through it, if you can feel it, you will need the fabric. rc might have that too.
take your time to ensure all straches are take out. dont want to rush.
for bigger area for fine straches, you can get a circular buffer kit from home depot that can be use with your drill (use that with the novus).
I used this method 5 yrs ago, so there might be something new in the market I dont know about... hope this helps
protip: When your working down to finer grains of paper go at a different angle with each grit. Makes it much simpler to see when all the marks from the last grit are out. By the time you're done shouldn't be anything but the finest grit marks left in the surface.
