Humbrol enamel

Question for any of our UK cousins: I have seen photos of this used on some major size Scale models "over there". How "fuel proof" is it and to what degree nitro? I have used it on plastic shelf type models for years and never tried it on anything else.
I looked at a shot of one gent's Heinkel He-219 night fighter that was about 6 foot or so span and painted with Humbrol and would hate to imagine what he paid for the paint in all those tiny little tins.

Gloss Humbrol Emamel is pretty ' bullet proof ' once it has dried. (which takes ages...)good for 10% Nitro.

Biggest available can I have seen is 250ml.mainly matt finishes.

Good flying

It is 100% fuelproof up to at least 20% nitro provided you apply it over a fuelproof finish. The matt paints are slightly porous and the fuel will go through it and attack the finish underneath, causing the enamel to bubble. When dry, you should apply a coat of machine oil (3in1) to the matt finish. This gives it a slight sheen and stops it showing finger marks. Don't be put off by the small tins, it has great covering power. The only snag is it's heavy.

Can it be applied over a clear polyurethane base?
I have this in mind for a rather smallish 1/2A Scale job, which is why I asked.

Thanks,

Jake, most of the polyurethane finishes that I have tried are also porous and have the same problem. However, there are so many polyurethane and so-called polyurethane finishes around that the only way to find out is to try it. The other thing about polyu is that it doesn't like synthetic oil.

Thanks for the info Dave. I'll give it a try. It's not like a NATs PA comp model is lost if it doesn't work. I only run straight castor anyway.
