Foam for Tray!

[foxloat]

I just got done removing all the foam in the tray in my superjet. Some people have told me to use the pink sheet foam that you can buy at menards since it doesn't absorb water. But has anyone used urethane pour foam before? it seems like it would be better since its expandable and would give good strength and also doesn't absorb water.

I filled my tray with the pink foam then used the pour foam on top to make it level and fill in any gaps.

But what would be the advantage of using the pink foam at all, if the urethane pour foam doesn't absorb water and would give better strength?

It will absorb water eventually. I think it weighs more too. However, about 30minutes into cutting up the pink foam to fit in your tray you are going to wish you went with the urethane.

Haha yeah I heard cutting the pink foam is about as much fun as removing the old foam! I guess i'll just use a combination of both like you suggested.

Removing the old foam was more funn!

That is pretty much exactly what was in your ski to start off with...it will eventually hold water, use the sheet foam and add drains.
