Title: -03 Finish
Post by: didymus21 on November 22, 2007, 05:47:17 PM
Can anyone tell me the EXACT finish that Larrivee would have used on a '98 satin guitar?  I'm going to be doing some repair work and want to know the closest finish I could use and the best place to buy it.  Thanks a bunch.

Matt

Best place to get an intelligent answer would be from Larrivee itself.
Hope the job comes out well!

Yeah, but I know people on the forum have repaired Larrivees.  I didn't want to wait the 2-3 days it takes to hear back from customer service there....

Call them. Even if others have done repair, the only place to give you an "exact" answer would be Larrivee.

OK, so they wouldn't tell me anything other than it is a "complex" satin finish that they use.  So, in other words, they wouldn't tell me.

Now I do need to know...who has done repair work on them, and what was successful repair finish used?

If I'm not mistaken its a UV activated polyester with a chemical suspention in for that satin finish.Its a pain in the butt to deal with it.The gloss is the same stuff but without the satinizing chemical in it.What are you planning and on what finish.You can always call me,I my be able to help you with your project.

Thanks for the offer, Rob.  I've got a beater -03 and wanted to try to do some drop filling on some top nicks.  Practice, so to speak.

I'd give Unclrob a call if you have any questions.

I gave my old L-03R the Orsinoized gloss and it turned out well, so that might be another option for you.

Repairing the UV finishes is a very tricky task. Most conventional air dry finishes will not adhere to the UV over the long term. Matching the gloss or lack there of is almost imposable if you do not have the same material. Often there will be a bit of variation from batch to batch so even with the same material but from a different lot there can be some visible differences. There is a dulling past that it put in the coating that creates the satin effect. It is also responsable for the slight texture that you can feel and hear ( the swish sound ) on the surface. Once this texture is altered the gloss goes up. This is what you folks are doing when you buff the surface. If you look very close to the buffed surface you can still see the remnants of the texture.
   I have discovered a trick the resolve the adhesion issue with non compatible finishes. French polish made with dewaxed flakes and applied with a pad with no oil will adhere to the surface for the long term. Conventional finishes such as nitro lacquer will adhere to the french polish. This resolves the adhesion issue but matching the gloss is still very hard.

Well...................its UV poly , you guys have that right.  satin has suspended particulate that creates the refraction of light.

Actually many finishes will adhere to it.  But to drop fill I'd suggest using CA or superglue.  Go to Frets.com.  Frank ford explains the process well.

Finishing is hell on earth.  So to tell you to sand it back and replace it with nitro that you can get through Stew -Mac , would be correct but problematic for you.

If you've polished your satin finish and there is texture left-over then you've skipped the leveling step (first step) with steel wool or wet-dry sand paper.

the easiest way to go is to completely remove the top's finish and replace it with nitro.
