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. |

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
