nitro over poly?

[TrevorOfDoom]

do i have to strip a poly finish before i spray nitro?
i've seen one person apply nitro to poly for a cool relic'd look, and i'd like to do the same, but i'm curious as to how it'll stick.
any thoughts?

If you rough up the Poly a bit it should stick...

The ReRanch 101 tutorial has all info you need to do this.

I would still try to strip the body myself with a heat gun. Or maybe not. Depends on the condition of the instrument you are refinishing. The bass will need to be level anyway if you don't want your new finish to look like funny.

Dark Horse from Lone Star Relics has done this to a Squier Tele bass. You might want to pm him.

I have heard that you can use shellac as a buffer between poly and nitro

Rough up the poly and use Zinnser B-I-N shellac-based white-pigmented primer-sealer between the poly and nitro.

I usually use poly as a grain filler/sealer and sand it down to 400 grit. Then I spray nitro on directly. Works great

I like to use Zinnsers Bulls Eye Seal Coat, which is a fairly new product available in quart cans and is free of wax. De-waxed shellac dries harder, is compatible with almost all finishes and can even be used under water based finishes where shellac with wax would be a failure. I like it much better than any other shellac I've used and now won't use anything else unless I absolutely must spray on shellac.

It's harder to find than the other stuff though. I haven't seen it in Home Depot or Lowes. I get mine from a trendy, high end paint store. If you go to the Zinnser web site you can find out how to find it. Around here there are only two stores within 40 miles that carry it.

It has a two year shelf life when unopened and has a date code on the can. I pay about $14 Canadian for mine.

+1 on all counts

I use several gallons of Sealcoat per year; I buy mine in one quart cans from my local Rockler store:
