Interesting. I did not know that abut the KTM factory.

What I found worked best for me was to tint the actual finish rather than the wood. I used to use a very fine brush. I believe back in the day they recommended the foam brushes but I never had luck with that. If you heat the KTM in a water bath it helps it flow better too. I don't use water base anymore so I don't know what the SV means in the KTM-SV so perhaps it's changes a lot since I used it.

You are absolutly right though, screwing up KTM is indeed a nightmare, hence why I don't use it anymore.

KTM Factory info is from LMI.

[:Y:] Thanks J.F. for the water bath idea, makes perfect sense! [:Y:]

I was warned that toning the finish would cause problems but not how or why, so either I agree with you because that does not sound right (lack of info), or because it would just be so much easier to not have to fiddle with a blotchy dye job. I have had no problems with dyes so far, and am more worried what brushing the finish may do to the dye job.
gaah

I did test the dye on some swamp ash, and wiping it on I could not get it into the open pores no matter how hard I squeezed and rubbed, so it is already proving to be a ich. It does enhance the grain nicely on the ash though. Maple is way easy in comparison. I am going to redo the experiment, and use a tooth brush on the stubborn areas to overcome the surface tension of the solution.

I kind of want to do both: dye the bare wood, and tone a few coats of the finish. Toned finish has a groovy glow about it dying the wood can not achieve, and makes for a subtle but good effect when using two colors, one on the wood, and the other in the finish.


I hate those foam brushes!

What kind of personal safety and exhaust do you use with product you are using, Stuart?

Alex


I have a strong wall mount exhaust fan. I still use a respirator but I'd add that it isn't necessary.

I used polyester gel-coat in business years ago. In a closed room we sprayed small amounts of gel-coat (very similar to clear poly...catalyzes with the same MEKP...Methyl Ethyl Keytone Peroxide). We used more in one session than you'd ever use on a guitar. You'd think that was nasty stuff but the catalyst was used in such small quantities that the Washington State Dept of Labor and Industries set us up with a "voluntary respirator" program....essentially allowing the employees the option of wearing a respirator if they wanted. Two guys from the state spent a whole day in there with measuring equipment.

In a small, closed area I'd use one. Mine is a 3M 5301 with organic vapor filters.


I have to admit I am interested in doing some test panels. (pore fill). What brand "cheap" gun are you using? I'm not sure I want to run this through my good gun. And what cleans it up?


Acetone...and one of the cheap Grizzly guns is fine.

If you order a new one...see if you can't also order various orifice sizes at the same time. Having options on size provides great latitude getting liquids with varying viscosity to lay down nice.

I have a half dozen HVLP gun laying around...a collection begun decades back.

I keep meaning to ask... does the sealer itself provide a degree of hardness on the the top? (assuming you apply it to the top)
