I bought a used SG STandard with a little too much light spider webbing caused by some over-zealous pick action and light buckle-rash. I had ordered this to try and I was impressed.
20 minutes of polishing with small circles and they'd pretty much gone. I compared my SG to a brand new one after using the polish and mine was honestly much cleaner and fresher looking. I used it with a micro-fibre cloth and I'll keep using it. Oh, it also did a great job on the pickguard removing a lot of the marks.
If I had to make a small 'moan' it would be that I'd of liked the option to purchase a larger bottle of the polish. I need to wait until I have enough of a back order to get another one or two. That said, I didn't use much at all, I just intend to use it on all my guitars when I change the strings next time.
I guess 10-15 guitar polishes is about what I'll get from a bottle.
