@@olly22n Cracks normally are ground out to give a 12:1 depression. So if fibreglass is say 4 mm thick you would feather the sides back to about 48 mm (12x4) either side of the crack, then fill the depression with wider and wider layers of fibreglass to make up the 4 mm. Then apply your additional layers. :)
a question oliver.. seats are mounted to de fiberglass floor ? or you will mount them to the roll cage for obvious safety reasons ? cheers from Montevideo - URUGUAY
