I have to fix a slide going to a pool.  It's curved, so a new one is big bucks.  There are some cracks int he bottom for FAT fucks trying to go down, and a good size missing form the top (say 18x18)   
Could fiberglass be sued to fill that gap?  For all slide repairs?  Do I have to stick with epoxy?   
I was thinking epoxy the stress cracks, and fiberglass the gape.  Opinions?     
Thanks
