Nitrate dope and Lusterkote

[Phil Coopy]

Just found out the hard way that Lusterkote doesn"t stick to nitrate dope without primer. Question does it work with primer? Possibly if I mix in some MEK?

I've used Butyrate without primer and had no problem with Lustrekote. I haven't tryed Nitrate with or without primer.

Well I'm back to the nitrate coat....the adhesion was so poor that the Lustrekote peeled off like a layer of plastic wrap. Fortunately the only part I painted was the fuse on my Ringmaster (before assembly). The paint job looked great until I pulled off some masking and the color basecoat came with it.  I'm gonna' go conventional and use dope this time.

I have stated this a few times. Lacquers are chemical bond and enamels are mechanical bond. You must have a primer between the two. (or a trick)

Where does epoxy fit (what cate ???gory)?

[RC Storick]

Epoxies are a chemically activated mechanical bond type paint. Most Epoxies are activated with MEK. The MEK is sometimes hot enough to act as a chemical bond. So you get both property's in one application.

This is one reason I use lacquer thinner in my Urethane applications.

Thanks for the info.

Lustrekote goes over dope just fine, but you are correct, you cannot dope over Lustrekote, it won't stick and you have a mess.
Sparky knows all the techy info on this one.
