Hello all! I just curious about everybody's finishing schedule for nitro. I've seen stewmac's, and I've read of a few that are different. Whats your finishing schedule? |

Sorry to double up on questions, but I've got another. Stewmac claims that you can wetsand and buff after 4 days of curing. Is this REALLY enough cure time? |

I don't use nitro no mo, but I think a month is good. |

I use nitro--at one time, only Lawrence-McFad but switched off to Behlen when L-Mc had production problems, etc. Here's my schedule, and it has worked pretty well for me. I've never had a major problem and can generally part my hair in the finish when it's done:
Use whatever dye I am gonna use to get the desired color (tape off binding before dying). Sand back the dye and re-dye if I am trying to emphasize maple curls, etc. Hit everything with some sanding sealer (generally, shellac in a 1 lb cut). Very light sanding with 320 grit then pore fill with Timbermate thinned and stained to closely match the wood I am filling. If I am finishing very pourous wood (oak, walnut, etc.) I will sometime use some Z-poxie under a razor blade squeegie. I sand the Z-poxie (if used) very lightly between coats, and don't quit until I have everything pretty silky smooth (check it out under a light and look for the low spots). Z-poxie is not always necessary if the Timbermate does its job well. Another coat of shelac (just to make sure all the pore fillers are sealed in). A couple of coats of vinyl sealer. Start building coats with the nitro-generally I shoot two coats per day with an autobody style HVLP gun about an hour apart--up to 10 coats total. I let the guitar sit for 10 dayst to two weeks and gas off. Wetsand up to 2000 grit. Finish with a R/O buffer and McGuires finishing compounds. There are guys on other forums who recommend a minimum of a month curing before wet sanding. I never wait that long. Generally, if I cannot smell and fumes, I think it is ready. |
