Starting my second DIY build and have been combing this forum and others for ideas and to refire the neurons about finishing... i had reasonable success with shellac and danish oil for my ash/wenge project a few years back (shellac on the ash, oil on the wenge). This time the body is all Swamp ash -- hasnt arrived yet, but im reading /prepping in the meantime. Planning on adopting a very similar method to Telegraph's fabulous thread here http://www.tdpri.com/threads/swamp-ash-grain-fill-with-dye-tutorial.371080/ (so useful it should be a sticky!) , but am reversing the contrast and trying a quasi "dog hair" /Silver Fox finish approach: Aiming for a gloss-y black with silver /metallic in the deep grain contrast. Thought about using a Wudtone kit, as they seem to have this idea already configured, but I'm interested in a more home -grown approach, lol Thsi thread here was helpful -- http://www.tdpri.com/threads/silver-fox-finish-how-do-they-do-it.320296/ and I've been looking at several other grain filler threads, but there doesnt seem to be a lot of resources on how to acheive a metallic grain filler. So I did some digging, and here's what I'm finding for options -- would love to get opinions and any experience: Jimmy Clewes Metallic Cream Filler per the page, " Often referred to as gilt creams, these metallic cream fillers are typically used as a grain filler or surface embellishment that adds beauty and contrast to wood. Real metallic and mica pigments in these cream fillers provide brighter, long lasting colors with excellent lightfast properties. The silky smooth texture also makes application and buffing easy. While they can be used alone, spectacular results can also be achieved by using more than one color over top of another for a layering effect. Solid colors are semi transparent and can be used alone for a pastel appearance or in conjunction with metallic creams. If for any reason you don’t like the way an application looks, you can start over by removing the cream filler using a rag saturated in Danish Oil. Jimmy Clewes Metallic Cream Fillers are compatible with most types of top coats. A top coat of quality sanding sealer such as Deft is highly recommended prior to finishing with a lacquer finish of your choice. If a cream dries out, you can reanimate it by mixing in a small of mineral spirits. Non-hazardous, these cream fillers can be shipped via Air or Ground. not sure what this is exactly made of and wondering about its efficacy as a grain filler for something as cavernous as ash...planning on sealing with Zinsser clearcoat before /after and using Fiebrings leather dye for the black. Anyone use this, or can think of any compatibility issues? Mica pigment powder This seems intriguing as a tint or mix if Im using drywall compound for the grain filler. Seems like it plays well with alcohol or water based layers. Thoughts? Metallic plasters There are some threads out there on other woodworking pages-- not many -- on using plaster as grain filler. Not sure how plaster as grain filler works on guitars, or if so, if these metallic plasters are chemically different from Plaster Of Paris. But its an intriguing idea. A couple of options: pearl paste "Pearl Pastes are acrylic water based pearlescent metallic plasters which offer limitless design possibilities. As a result of their relative high viscosity, these products are typically applied with a trowel and have exceptional tolling strength, which enable the achievement of rich lustrous pearlescent textures and patterns. Pearl Paste is available in 13 colors including blue, coffee, ruby, violet, blue & gold plasters." portofino "Portofino is an elegant, shimmering, pearlescent coating which is typically applied with a stainless venetian style trowel." CRB Pearl Metallic Powder Marbling Pigment this is used to color epoxy for fishing rod finishes... if one was to grain fill with ZPoxy this might be the way to do it, but im leaning towards the dry wall compound approach or maybe plaster. would love to hear pros and cons or observations on these options from the experts!
