Recently Apogee released a two-part epoxy with the consistency of modeling clay. The epoxy clay is similar to regular epoxy as it comes in two parts, part A and part B, that must be mixed together to activate it. It comes in two small tubs and weights ¼ pound and is scooped out instead of squeezed.

According to the Apogee Web Site "Once mixed together, the clay is still pliable for about 1-3 hours, so you have plenty of time to use it in your rockets. While still soft, it can be shaped, rolled, stretched, or sculpted. It sets rock-hard overnight, and then can be machined, drilled, tapped, sanded, or painted. It is water-proof, and has 0% shrinkage."

I have used up one tub at this time and have tried using it for a number of applications. The main thing that I have used them for is fin fillets. It will bond to just about anything from wood to plastic and is easy to mold and smooth. With a gloved finger dipped in rubbing alcohol, you can smooth and feather the edges so that they almost don't need to be sanded.

It does have some drawbacks.

It is not cheap. It costs more than the same amount of regular epox (although Tim might argue with me on this). It is also very sticky and not that easy to mix, I like to use gloves when handling epoxy. It must be kneaded between your fingers to mix it and it sticks to the gloves which creates a challenge. The epoxy is a clay-like consistency which does not allow it to soak into paper or wood.

This is a great product if used in the right place for the right application. For small to mid size models where small amounts of epoxy are needed to add extra strength and for creating and molding one of a kind parts this is your product. For large fin fillets or where you need a lot of epoxy or for it to soak in this is not the product to use.

I give this product an overall rating of a 5
