Brodak Crystal Clear Dope
« on: April 30, 2010, 11:04:20 AM »
Hello Pilots

I Know that alot of guy's and girls use Sig's Lite-Coat dope to finish there planes for a fuel proof upto 15% nitro
but where does Brodaks Crystal Clear Dope stand at ???

Is it fuel proof ?   

And how much nitro will it take ?

Thanks Bryan n~

It stands at about $30.00 a quart and if it is like most Brodak dope it doesn't tolerate much nitro. Some have said not more then 5% nitro. Frankly I prefer Glass Kote.

I guess i'll use polyurethane clearcoat .  I wanted to use Brodak Dope products all the way
but i have to use 10 - 15% nitro here in Colorado to get good engine runs. 

Are flying field is at 6100ft  elevation.   D>K

I use Randolphs (nice because it's about $75 a gallon). Seems fairly fuel resistant up to 10% nitro. But I usually don't use it as topcoat. I go with catalyzed polyurethane. It's very resistant to fuel.

Was Glass Kote a mis-print of Klass Kote, the epoxy, or a whole 'nother product?

Hi Randy,
 You mentioned that you use Randolph clear, I've been to the Randolph website and they offer several different clear dopes... nitrate, butrate, with  tautening and non-tautening versions of each.
Which clear is the one you've been using?
               Thanks,  Tonyk

I use Randolph Nitrate, tautening for undercoating balsa surfaces and for applying silk, then switch to non-tautning butyrate for final clear coats. I then use Brodak Crystal clear for final two coats after color.

That is complicating things to this old man.  I use butyrate from the first coat.  After reading an article that Windy U. wrote,  I thin the dope considerably.  Then I slightly remember Robert S.  saying something about doing two coats of base clear before sanding.  So far have not had dope lifting at the fuselage to flying surfaces.

My bad, I meant tautening butyrate for the final clear coats before color. I found out that the butyrate colors from Randolph are all non-tautening. John, didn't mean to confuse anyone, the Randolph stuff is cheaper than the LHS dope, so thats the reason I've been using it. Been back at this less than 2 years and have learned so much fron this forum and others. See, an old dog can learn new tricks! Even learned how to use a spray gun.

For Randolph Clear you want A-1690.  That is their untinted, non-tautening butyrate.  It does not have the slight yellow tint that standard Brodak Clear has.  I bought a gallon a few months ago at Spencer Aircraft in Washington and paid $43 for a gallon.  A lot better than $30 a quart for Brodak Clear Coat.  Most Randolph colors run about $22 to $25 per quart which is the smallest size you can get.
