The Local Painter

He is adamant that Laquer thinner is a better choice than urethane reducer, I have learned most everything I know on this forum and from personal experience. I just wanted to let everyone know that there are some guys who use the old school Laquer in the new base clear system.
 
JC Daniel, really want to piss this guy off? Send him a link to this thread...
Not sure I would do that unless you have other jobbers in the area to get your supplies.
 
I think the last time I tried using cheap lacquer thinner in base was around 1991. Even then it was no good. Of course back then you could get good thinner, I was just trying to be a cheapskate. But nowadays, good lacquer thinner doesn't even exist. Well, it's just changed names, it's now called SPI 885.
 
Back in late 80s and early 90s my brother in law was a jobber at a store that carried two of the big name paint companies products. Just paint , no car parts etc. I remember him trying to get the shops to start using this new kind of primer called 2k and also epoxy. Most did lot work and lacquer primer was king. Interesting to look back on. They didn't want to try something they weren't familiar with.

I worked in a PBE store when this was coming up, The hardest sell was the price, as the lacquer system was less then half the price. But it shifted quickly as the lacquer started going up and the 2K down, plus the high build and quality of the final finish switched everyone but the final few.

There is still paint grade lacquer thinner available, but it's very expensive, and other then a few specialty applications, there's no need for it. I have an industrial account that buys a gallon about every 2 or 3 years. I think they said they only use it to thin some old school adhesive.
 
the difference here is that urethanes use moisture to cure. lacquer thinner will have a moisture content in it that is probably through the roof. the moisture screws with the cure rates of the clear and primer. clear can kick too fast and or too hard. could be hazy, die back, have a dull finish, all kinds of issues can occur. good urethane reducers will have a super low moisture content. that is what the "urethane grade" means. you dont have to worry about moisture content with lacquer since its not cured with iso.
 
That's interesting about wanting to use lacquer thinner, just the opposite is true.
I do a lot of cabinet building in my wood shop and use a commercial epoxy finish
made just for cabinet makers, it's called "conversion varnish" tough stuff.
It specs out that you should use lacquer thinner to reduce it. (MFG specs)
But a lot of finishers on my woodworking sites complain about problems
these days and thanks to what Barry told me years ago I recommend them to use
urethane reducer to thin their product like I do.
It really does work much better for flow out and smoother finish.
So no way would I use lacquer thinner in auto paint.;)

He told me that I did'nt know what I thought I did about paint materials, He said he used urethane reducer before and since he has used laquer thinner he can tell no difference in anything he has done. I said before that he painted a black truck and the whole truck's clear coat was like a hazy milky look and he said he had no idea what happened, I told him it looked like a moisture issue and he said he never has moisture problems. Jim C said laquer thinner has a lot of moisture in it and that was probably the issue with the clear. This guy is my friend and I like him but he just will not listen to me on this issue. I appreciate your advice and experience.

I second that JC.

Leave the guy be. In regards to this type of work he's a dumbass. Arguing with them will get you nowhere. Trying to reason with them will get you nowhere. Just do your thing, and show something to him one day. Ask him why his stuff doesn't look like this. He'll hem and haw but inside he'll know.
