Film covering types and fuel resistance?

Gentlemen:

I was all set to install a dirty diesel (PAW 19) on the front of my ARF Flite Streak, when a distant memory began nagging from the depths of my memory... I vaguely recall a magazine article commenting on different types of plastic film covering (polyester vs polypropylene?), with one type not well suited to diesel fuel.
Does this ring bells with anybody?
Which film type is the MonoKote on the Flite Streak?

Any advice much appreciated.

This is what I have on mine. Only area where there has been any problem is around the nose. The covering has let the fuel seep below it and loosen it. Other area to be careful of is the clear canopy, be sure it is sealed everywhere or the brown exhaust will get inside and look horrible.

Just a thought. The nose of the FliteStreak ARF has a reputation for being quite flimsy. It's possible that the PAW may not be the best choice.

I think I remember one post which described wrenching the nose off by using an electric starter on a glow engine. The rather spirited prop-flicking necessary with the PAW seems likely to do the same . . .

Another "stinky" engine guy,

Correctly applied, no electric starter I know of will cause damage to nose of an ARF Flite Streak. I constantly use the weenie option when starting my (insert designation of engine we are no longer allowed to talk about) and there is no problem whatsoever.

On the other hand, an improperly applied electric starter can be persuaded to rip the nose off a per-plans Oriental (no ply in the nose as originally designed).

If I'm remembering correctly plastic film isn't bothered by diesel fuel with the exception of the adhesive. Be sure to seal all edges so fuel can't get under the film.

Actually the cheaper, low temperature films have a tendency to shrivel when hit by diesel fuel. It really makes your model look bad fast.
Monokote and Ultrakote are not affected.

polyurethane glues(Gorilla glue, Elmer's Pro Bond) do a good job of sealing covering edges. Sticks better to the edges of most coverings better than anything I've tried, and it tends to dry to a solid edge, making it more durable. CA, epoxy, all will tend to let fuel seep under eventually.
