Wood veneers for exterior

My plan is to build a true woody teardrop and I was wondering if anyone has had luck applying paper backed wood veneers to the outside or their trailers? I wanted to have a darker color on the exterior and found out that birch is a pain to stain, especially with the limitations introduced by later applying epoxy, mainly no conditioner and only water based stains.
To give some more detail, I will be skinning the exterior walls and roof with 1/8" birch and applying the veneer to that. I will also be using epoxy and spar varnish to protect and finish the exterior after the veneers are attached.
One problem I can foresee is applying pressure to the veneers which will need to have very even and total coverage. I was thinking I could use veneer glue which after being applied to both surfaces could be reactivated with an iron. I have heard this is a very effective technique.
Again, thanks ahead of time for your suggestions.
Cheers,
Ryan
