I've had good luck using Doculam. It's sold in 500' rolls and turns clear as it's applied. It does not shrink with as much force as Monokote and is less likely to warp light structures. It is easily...

Soldering will produce some smoke as the rosin burns. That can be fairly pungent if there is not adequate ventilation. Perhaps that was the cause of your reactions.
