I'd like to add some cherry nitro to this spot but how do I avoid the dark line around the perimeter that typically forms from adding a touch-up? I.e., what is the best strategy for blending what i'm adding to what is there?

*Photo added* Ding repair on spruce top, 2015 Collings 0002HE #23701. What are y’all reaching for when repairing dents in nitro? GlueBoost fill & finish or drop filling with nitrocellulose? This is a well-used guitar; not pristine and the owner has reasonable expectations that the repair will not be “like it never happened” Bonus question: If there is bare wood, should I seal it with shellac to preserve the color before proceeding to fil…

Someone recently contacted me about a Gretsch in need of some finish repairs on the binding. This looks to be nitro that has chipped/flaked off over the years and possibly yellowed by nicotine. I'm curious if any of you have experience with this type of repair and what the best way would be to go about it. I'm not anticipating taking this on but I would be interested in knowing the procedure. Thanks! Images

Hi, Any recommendations for scratch safe and nitro safe bench coverings? Also the porous sanding mats compatible with vacuum tables with same nitro safe properties? My material science education is low in regards to stuff that will and won't react to nitro. Thank you.

So this 310 came into the shop and had a pretty gnarly crack that splinters some toward the lower left bout. Going to do a crack repair with the TJ Thompson crack corrector and some hide glue. The issue I'm inquiring about is the finish is delaminating around the area. I'm curious as to what type of finish it is. Seems a bit flexible and spongy to be a nitro alone. There's shards of finish missing, and dirt has found its way underneath…

Hey all! Anyone know what lacquer pigment might better match the deep black colour of this tele body? It’s an American tele deluxe with a nitro finish. Photos show: Finish damage was the size of a quarter. I’ve filled and levelled the area and sprayed on coat of Oxford black nitro. I poured a puddle of naphtha on to check the match and unfortunately no dice. I’ve used Oxford black many times for overspray during repairs and have always fo…

Hello fellow looths! I recently had a customer come in with a '71 Fender neck that is a fusion of the 60s and 70s style. It has a veneer fretboard, no skunkstripe, 4 screwholes, 70s style tuners, 70s headstock logo, and it seems like it has a poly finish on the back of the neck, and nitro (with cracking) on the front of the headstock. Can anyone tell me if this combination is possible or could it be fake? Another thing is, even without th…

Okay gang I have a doozy of a crack repair. Young guy brought in a Epiphone LP Limited Ed. He had picked up the case while it was unlatched at the guitar took a nasty tumble. Severe finish damage, and the wood has a shear split in it as well. The undercoat is thick with a thin layer of nitro color on top. Spoke with a sweetwater rep and they said that the finish was nitro. Here's the guitar specs via Zsounds: Epiphone Inspired by Gibson…

23 yo acoustic in for touch ups. EIRW, nitro. Has a couple of spots on the sides that look like this. In good general shape. What’s going on here? No texture, its under the finish.

This is just a rant against the Stew-mac touchup pens. Ive just never had them functionally work, without creating more of an issue than there was in the first place. Through an "act of god" I chipped a small bit of freshly buffed and polished laquer off the headstock of a Taylor that I refinished. The guitar had that nasty bubbling around the tuners and CA glue didn't fix the issue, so I stripped the front of the headstock and airbrush…

Hi there looths, Hoping you guys can help me identify what uv resin or other compatible finish can be used to finish this crack? I'm comfortable true-ing up the material and gluing, however I've only really done nitro or polyurethane finish touch up. Thanks, Aleks

I'm still working on this 1958 Country Gent and I am getting closer to getting past the structural stuff and on to the finish work. The entire body appears to have been resprayed with what I'm guessing is some sort of poly a long time ago. It's very yellowed, has multiple big drips across the entire body and flakes right off in big pieces. My plan is to remove it all, clean it up a bit and then respray with nitro. Anyone have great advi…

I'd like to start a discussion about guitar polishes. We have always been careful to use only non-silicone products on nitro finishes. We previously used Stewmac Preservation polish for years, but they don't offer that product anymore. We recently had maybe what was a bad batch of Stewmac "Clean and Shine" that was softening nitro finishes so we trashed it and haven't purchased anymore. The first bottle we got worked great, but the s…

Folks, I’m trying to make some homemade oil based pore filler to go underneath a 50s style nitro finish. I know pumice is one ingredient but don’t recall the rest of this recipe. Does anyone here have experience with this? Thanks!

I’m serious here, maybe crazy or funny, but please forgive me should it be obvious, because I don’t know shellac good enough to really know by experience if that’s doable or not would it be stupid to use some recipe on shellac for an electric Bass fingerboard finish? Would it be a good “filler” or way of giving some body in preparation for a finish like nitro or poly? Would it scratch like hell sooner than later? Could it be easily rebuilt…
