If you aren't French Polishing, but using a different type of finish i.e. KTM9, Nitro, Target USL...do you use a seal coat of shellac before your final finish? |

Yes. Some have said they have had issues with KTM9 directly over Zpoxy or other epoxies. Others say they have had not problems at all. I always seal with a 1# cut of shellac before spraying nitro or KTM9 |

use a seal coat of thinned epoxy about 50% DA or better yet grain alcohol like everclear, wiped on thin. |

I had issues with KTM-9 over shellac, but I think it was because I didn't sand the shellac. It was too slick a surface for the KTM-9 to grab hold of. It needs a good mechanical bond. I've tried it with shellac that was sanded, no problems. |

I use McFadden's nitro, and I use their vinyl sealer on top of pore fill, but not shellac. However, I tend to sand back the epoxy so it remains only in the pores; I don't like the color or texture of epoxy on top of the wood grain. It's a bit tedious, because it's easy to overdo it and remove the epoxy in the pores, but it's worth the effort for me. |

i have only one experience,, KTM9 over system 3 epoxy on maple.. Didn't need to pore fill, but liked the tone the epoxy gave to the maple. The KTM9 was cold and very clear. No trouble with adhesion. Mike |

Like the crazytooguy above I've been spraying McFaddens and use their vinyl sealer over the epoxy. I've had no adhesion problems . I've used various brands of epoxy for pore filling and recently tried the Zpoxy stuff from LMI and like very much as it sands really well. |

Same here. I've used Oxford PSL and more recently KTM-9 over System 3 epoxy with no problems. The oldest one of mine is about two years old and no worries so far. |
