How difficult is it to remove badly failed(micro blistering) gel shield?
40ft Mobo,4ft draught,it's a large area:(
What blasting,if any would remove it,I understand the gelcoat underneath the gel shield is softer and creates problems when blasting?
Or is it as I've read on here a case of just pushing a random orbital sander into it and gritting of teeth,or pay a yard,how large would the cheque have to be?
Many thanks.
