I Like what spoonta says. At first I was thinking fiberglass is a bit too much, but you'd want to be damn sure you fill those holes if you're siliconing it.
Any surfboard manufactures or shapers near you they have always got scrap fiberglass laying around or try a surf shop and get a ding repair kit!
no mate just fiber glass and resign do not use silcone as the glass wont stick to it
I left my styrifoam bare. Never went mouldy. Now of course if u spray beer on anything it will go mouldy.
in my second keezer conversion I used enamel paint when I was priming my timber. Thst should see u right rather than screwing around with fibreglass
Bunnings has builders bog in small tins should do same job for about $10.Yeah also if u dont want to mess with fiberglass you could scrape some of the foam out and just use 2 pac car bog. it will seal it up and go rock hard too. and if it looks too shit just paint it and it will look like the shelves were never there.
Oh and yes he ment resing not go and quit your job
