Buzzy bars

[CRH]

ooooooo, liking the idea of expanding foam.  I've never used the stuff myself, are there different types? If so, if there a particular type I need to be using or is expanding foam expanding foam?

Possibly a bit of a noob question, but thought I'd best check.

just use the make/brand available to you!....best to ware gloves when using it?...but its supplied with a long nozzle which you insert in bar anyway?..so you should not find it messy??....just make sure to leave it to cure?..usualy ..15mins in open air will do?..
