Much has been posted about reducers.  I am getting mixed technical information.  Can someone post a link to an authoritative site that dispels rumors and states why you use a reducer that is labeled for Nitrate with Nitrate dope and one that says Butyrate for Butyrate dope?  I an not talking about experiences some have had, good or bad results as there are a lot of other factors to include, just need the reasoning behind this issue.

Bill,

Thanks Pard.  I was darn near sure my thinking was correct but before I get started on my next painting project I wanted to be sure as I can be.  Brodaks new paint supplier says that the two "thinners" they call them reducers BTW are formulated differently to eliminate the problem of the paint craziing and cracking.  I am going to be investing a lot of time masking and re-masking [dad-burn you Randy Powell You made me do this  ] that if it goes Sout I'm gonna be one unhappy camper.  Now you, I totally trust.  And Thank you for spelling out the thinner - reducer issue, there's a lot of misinformation going around.  Me? I always called anything that thinned "Paint" a thinner.

What is a reducer please?

Hi Ron,

Who uses it most, Dunno, but if you hang around the automotive crowd it is used an awful lot so since they use 2 part ummmm, paint?  you probably nailed that on dead on.

Hi Dennis,

Here's a couple if ideas to try.  First, google DuPont and go to the link in their site for paint, automotive finishes or do a site search for acrylic reducer.  Use the yellow pages to find a dealer for automotive paint, or look up a body shop and ask for the paint guy and see if he uses DuPont and where to buy it.  If memory serves, Nason is a division of Dupont and from there you can source which Dupont product you want.

Hope this helps

Guys, still looking for Dupont reducers. No one seems to carry Dupont stuff in the Philly area. I am still checking. There's a lot of lacguer thinner around in the automotive paint stores. Usually fast dry or medium dry. It's quality thinner according to the men behind the counter. Any other lacquer thinner that you know of to work with Brodak dope?

Make sure when you find the Dupont thinner that it is 3608S.  It must have the "S" suffix.

There are other suffixs for 3608, and so far they have not been acceptable for me.  Only the "S".

I found one place that can get the 3608s thinner, but does not stock it. I would have to purchase four gallons at $16 a gallon. Which means $64 dollars worth of reducer. Not much more expensive than acetone though at Home Depot which I presently use to clean my spray equipment. So I'm considering this and will look elsewhere. The automotive paint industry of course no longer uses lacquer much, a function of the EPA and more durable easier to apply finishes. Lots of our model airplane friends also have strayed away from dope. Has anyone used lacquer thinners from other brands to thin Brodak dope? I can buy that stuff up the street. Virgin lacquer thinner, either fast dry or medium dry. I'll probably get a gallon (can use it to clean spray equipment I guess) and mix and try a test patch.    

I've hit the Dupont website a few times. No phone number available, which means email inquiries only. My search for an alternate to Brodak thinner began when my primary supplier of things Brodak told me Brodak thinner was on back ourder. Called Brodak this past week, however, and it's not a problem to buy some retail from them. So the major issue is almost academic for the moment. However, I'm still interested in an alternative reducer that will work without a hastle.

Thanx to all.

Thanks for replying Randy. I'll keep all that in mind.
