hi jason hysol 9462 is a epoxy based product if you do your home work you will find that it is just simply epoxy and micro balloons mixed together just because a certain model manufacturer label it as areopoxy does not mean it is some thing special and the gun you need is a rs products model number is 503-379 that is if you are going to get the cartridges if not just mix epoxy with micro balloons and you will have the same thing and i would use wing skinning epoxy as it gives you more time and pipe it out off a plastic bag just cut the corner off it and pipe it out regards jetman
