    Paint help needed

    Hi, I'm new to the forum, and just getting back into the hobby after a long hiatus.

    building a Sterling 1/2A CL scale Fokker D VII from plans. Have it covered with Brodak silkspan, which I'm very happy with, but not happy with the Brodak dope, and thinking of switching to something else before I get any farther along.

    What is everybody using for paint (fuel proof) these days?

    aerogloss out of business, Formula U same, perfect/chevron same.

    thanks,
    Frank

    If Sig still sells dope, that would be my first choice. I use Randolph from Wicks Aircraft.

    Thanks Jim. I'm starting to figure out that humidity is probably my problem. Brodak dope is made by Randolph so it should be compatible. Does Wicks sell hobbiest quantities? I don't want to buy a gallon. Would prefer smaller than a quart if possible.

    Wicks has an on line catalog. I don't know how small amounts they sell as I have only bought quarts of various clears. They sell a retarder. I have used Sig retarder with good results. I generally add a little bit to start with. With blushing happens, I sometimes brush on pure retarder which solves the problem.

    High humidity will certainly cause blushing in dopes. It is not a problem at all. Just wait until dry (24 hr.) and spray a coat of dope thinner over the surface and let dry. That will release all of the trapped moisture and return the gloss.

    Thanks. I'll try that.

    I buy mine from Aircraft Spruce. They carry Randolph dope available in butyrate and nitrate tautening and non-tautening in quart quantities (smaller quantities will have to come from a hobby supplier). If you buy quarts, there will be no haz-mat shipping fee attached. Just use their search function for butyrate or nitrate.

    Any dope, in any humidity above 50% +/-, will give one Heck if one does NOT use a "retarder" in the mix. Retarder slows the drying. Here in SE TX even in summer, (especially with the normal high humidity) retarder is definitely required. In winter, same!

    Brodak and Sig are Randolph. I have used several aircraft varities and all require some retarder. My shelves now harbor Brodak, as it seems to do better. Brodak spent a lot of time and money getting Randolph to use his formula, some years ago.

    +1 on the Brodak Dope. It has alot more pigment in it & needs to be cut with more thinner than some of the other brands. I can get even the light colors to cover usually in one pass with the air gun. I now use it exclusively with excellent results on my models. I have a build thread going on RC Groups in the control line forum under" Brodak Shoestring build", where i am useing all Brodak paint over silkspan. ( i guess i can say that on here)....Gene

    Aerogloss was thinned to consistency for brushing out of the bottle. My Sig bottles are getting old but if Sig is still the same, it requires cutting with thinner for use.
