I had a finished top that just needed sanding and buffing but I noticed a slight bleeding from the rosette are... I sanded that area all the way to the wood and sanded away the stain. Now I'm re-applying KTM-9 but that area is a lot lighter that the rest of the top!

Do you guys think it will darken up while it cures for the next week or so? Or should I just sand the whole top down to the wood and redo it?

thanks

Question . You do not use a sealer before applying the finish? I always seal all rosettes, purfling and bindings with shellac before pore filling and seal the entire guitar with two light coats of sprayed shellac before applying finish.MichaelP38918.6038773148

what did you use on the top to seal it? It almost sounds like you forgot to lay down more epoxy or shellac etc under the new finish. I would refinish it myself. Done that a lot!

I don't normally apply epoxie or sealer to the top as I like to keep as thin as possible.

Thats why I'm confused
there should be no color difference....

welcome to waterbase - I had a similar issue, but a rubthru on a walnut top, and then resprayed PSL - it looked pale in the area and would not blend to my liking (ie - this wont sell). Stripped it all back, and switched back to nitro. After that, I gave the rest of mine away.

I have had times when a guitar sits around the shop for a bit before I can finish it. When I pick it up again sometimes I give it a light sanding and notice that the top now has streaks. It had actually darkened from the UV light in the shop and I sanded areas down to fresh wood underneath. You must then thoroughly sand the entire piece to get the color uniform again before finishing or you will have streaks.

Good call Robbie. The color difference is probably due to oxidation in the wood.

I recommend sanding down to wood and going at it again. The only way you'll get a perfect match. Or do what Hesh always does on all his guitars...SUNBURST
