Resin requirments

OK so if I were back in the states I would use the standard bondo and resin kits, however here in New Zealand I am limited to certain types of resins. I am trying to find a resin for a pep model and as it is my first one, I don't want to use somethign that will destroy the card stock. Any helm would be appreciated, just trying to figure out what to use?

Im in Australia im shore most prods are the same here as there if yu tell me what you are making and what you are using it for and all that ill give you a list of every product that can be used for all the difrent types of building props models sculpters what ever '
But basicly bondo is a brand its like what we call builders bog (i personaly use plastibond it is the top of the range in 2 part epoxy ) its a 2 part epoxy, but bondo being a brand has glazing puttys , fiber glass resins and a few othewr things,
but teel me what you are making and ill give you a full list
