Dude,

I don't want to be rude, but all I want to know is if some bubbles are normal. I am somewhat new to these planes and that is why I am asking advice. I have a degree in mechanical engineering and have a very thorough understanding of basic fluid dynamics.

The foam is fine. It doesn't need a thorough investigation as to whether my foam is better than other foam. This has nothing to do with it. As I said the tank is in there tight.

I am sorry, I don't mean to be a jackars. I've had a long day and it gets under my skin when I feel that someone acts like they have all the answers.

All I ask is if some bubbles are normal.

Thanks,

Wings
