I have to re-finish a water based finish (KTM-10 demo finish) and want to clean the surface thoroughly of all waxes etc. from some Maguiar's products. Ntw officially waxes but I think there's SOMETHING in these finishes and would like to clean the surface really well. What should/could I use to clean up a water based finish really well?

I would clean with naptha first to pull up any waxes that may be there and then with DA to get the silicones. I would clean again with DA after prep sanding for the new finish. What will you be putting over it?

Sorry to sidetrack, but what happened with the KTM that you need to redo over it?

Water borne finish again Brian. Probably the KTM if I have enough - Poly Whey if I don't.

Sanded through. VERY, VERY, hard surface after 10 days but had some stubborn scratches that I just couldn't get out so I went too hard in one little place - you know the rest of the story. I started too coarse, 320, and those scratches just wouldn't go away.

On a different guitar where I used the KTM again I level sanded the next day with 600 grit and it was much more reasonable to level by hand. 10 days it gets very hard to do by hand.
