I've seemed to run up against the fanatics of AQMD California when it comes to solvents.  Seems the Air Quality people in California are banning just about any solvent you can think of.  So far they are going against the thinners in nail polish, lacquer thinner, acetone, denatured alcohol, and who knows how many other products.

Does anyone know of an alternative to all of these?  I did look at Aircraft Spruce Company, and they do sell Nitrate dope thinner, but it is $75 a gallon, shipped UPS.  Home Depot supposedly sells Acetone and Lacquer thinner at the local store, but it is supposedly banned in California.  I am wondering if the formula is different, and if they are still effective as thinners for Nitrate dope.

I remember that California was trying to ban BBQ charcoal, but not sure they succeeded.  From what I understand, California will be trying to ban sales of gasoline and diesel fuel in a few years, forcing everyone to go electric.  No, I doubt they can do that, but I wouldn't put it past those  in our government to try.

Hopefully the local Home Depot Acetone or lacquer thinner IS usable for thinning dope, and it is still available there.

crashcaley,
Have you considered Krylon spray? It is still available and it works for me.

The Calif Home Depot Klean Strip brand does NOT work with nitrate dope. The automotive Rustoleum might be OK but at the price they ask, you might as well get Randolph nit dope thinner. Heres the Home Depot offering: https://www.homedepot.com/s/lacquer%2520thinner?NCNI-5

There's always the future floor polish route FWIW. Lacquer makes snot out of dope.

Norm, Thanks for that information.  Yes, might as well shell out the money for the Randolph stuff.  I kind of figured that might be the case.
 
Crabby,  Yes, I've heard of people using Future.  It probably is good for coating the tissue,but wonder just how good it is at adhering the tissue to the balsa.

I dislike using the Randolph for brush cleaner.  Anyone here in California tell me what I can use to bathe my brushes in to get them clean, that doesn't cost an arm and a leg.

Crash,

I've been using Home Depot lacquer thinner to clean brushes for the last couple of years - it does fine cleaning both butyrate and nitrate from the bristles.  I haven't used it to thin either type of dope, but it does work well to thin enamel and Tamiya acrylic paints for airbrushing onto doped tissue.

You can use a glue stick as long as it is the permanent one. It will say “permanent “ right on the label. I do really well with it. I also think Flyguy does too. I never tried Future, but some guys swear by it. What about EZ Dope? Home Depot acetone will clean lacquer out of a brush.

Look at ordering quarts instead of a gallon.  That may decrease the shipping cost from Aircraft Spruce.

I have an older can of Klean Strip lacquer thinner. It’s not good for thinning dope, but it’s OK for cleaning brushes. In the attachment, the can marked “South Coast” formula, I would be leery of. The quart can is not marked this way and maybe it’s OK for cleaning (but not for thinning!)

I'll give the Home Depot lacquer thinner a try for brush cleaning.

I am going to order a gallon on the Randolph nitrate thinner.  I probably won't have to get another can before I go ten toes up.  :-)

I  am asking lots of questions so I don't have to waste money on something that won't work.  The reason is as stated before.  I am presently walking or taking a bus where ever I need to go locally because of a woman failing to stop at a red light, and totally not only my car, but another.  I have been saving every penny I can to purchase a replacement, so I don't have a lot of money to waste right now.  Hopefully the vehicle problem will be solved in a couple months.
