It's been 15 yrs. since I did this , so I'm recalling a little at a time , easiest stuff to bond your inner firewall is called core-bonding compound, very strong -long open time , fills voids, for a roller you want a grooved laminating roller.. a cheap plastic one works just fine, don't try to brush resin on matt , stipple it on , then roll out bubbles [resin & air]
