I put this up on another thread (tried to remove it from that thread but can't).
I think it may be of interest to forum members, I have nothing to do with the product etc etc.
Here we have a commercial product that produces a dueco style finish, it's expensive and in Australia so probably hard to get hold of, it also requires some skill to apply it. If, or rather when I make another reso I might just have a go!

Interesting ! It works like a stencil, in fact.
I've tried marbling and scumbling which is not a dissimilar effect but a bit less subtle ! Actually a marble guitar would look good !

FYI there is a crystal lacquer sold here in the USA by Jurgen. Just google it. I bought a pint last year but have not spent much time with it, yet. Did spray a bit onto a metal tin and gave a very duco- like pattern but it seems to be somewhat fragile. When I sprayed some nitro over it, it disappeared. But in no way is my simple test conclusive. ( just want to say this s a great board and MM is a great host. I hope to be more active. Thanks)

Hi there !
I searched about a bit and found this :
"November 19, 2011 A. 'Frosted' or 'Ice crystal' finish can be achieved simply without harmful chemicals. A saturated solution of Epsom Salts in water is brushed on to a primed, painted or otherwise prepared surface. The solution is allowed to dry and large, flat crystals form as it does so. The speed of drying modulates the crystal size and appearance. Once dry, the colour-coat is sprayed on all over the surface.Any solvent based paint can be used. I understand Nitrocellulose paints were popular then and can still be obtained today. When the color-coat is dry the surface is swabbed and washed with water to dissolve the Epsom salt crystals. An abrasive washing-up pad may be needed in some cases.Parts of the colour coat come away in this process leaving the remaining paint in a crystal like 'frosted' pattern. A clear protective varnish coat can be applied if desired.

Looks like a similar dscription to what the guy in that video seems to be doing, no ???

Yes, I saw that blog Snakehips, but the guy says he couldn't top coat it because the effect dissolved!
Since I've never seen a Duco up close, are they smooth or do you feel the texture?

Interesting. I dd not see that blog before, but same results I obtained with the Jurgens lacquer. I have several original Ducos and you can sort of feel the crystals. So may nt necessarily need to topcoat. Or perhaps poly or other non nitro finish would work. Remember lacquer melts into lacquer.

Hi again !
I had Dark Walnut duco 1931 Duolian a while back.
The Duco finish was very tactile - you could feel all the crstals - not at all unlike all the later Duolians that are smooth on the surface.

There have been a few discussions on this forum about how to replicate a 1930s National guitar duco finish, and during the past 37 years that I have been around Nationals I have seen quite a few attempts at doing it. However, so far nothing I have seen, apart from Rik Besser's beautiful work, comes anywhere near the finish of an old National. Everything I have seen, apart from Rik's work, looks fine on motorbikes and hot-rod cars, but you wouldn't want to see it on a National or National-style guitar.
Shine On Michael

I would strongly agree with Michael...I was not too impressed by the result, as per applicability to duco in the above video. But I would dare to suggest that the Jurgens lacquer I fooled around with has the potential. It smells toxic enough to be the real thing. If the snow ever melts here in nj I may try to get out to the shed and try it again. The stuff was pretty cheap and if you live where it can be shipped, I suggest you try it.

I like the Duco finish on the guitarguru site, and as its his first Duco guitar I think he could do a "Good-as Rik" finish with practice , but it needs the 3 things to come together.... Skill as a sprayer , passion for guitars and time. PT The video (you have to search a bit) does tell you how to `Duco`, so the info is there for some keen spray-booth owner to get going. Meanwhile Rik is (it seems ) the only regular Duco sprayer , and will most likely be the best for some time

Okay guys, I never talk about how I do the frosted duco, because for me it is just this simple. No process, no technique, no problems. Just shake and spray. You just never know what you will find at a garage sale.

A large number of forum members are looking at the dusty shelves at the back of hardware stores as I type this. I think if enough forum member call Du Pont they will start production again! PT Seems like Du Pont stopped paint production in the `80s, might have to call Dulux
