what would be the best way to repair hairline spider cracks?
I've watched a few youtube vids but one was saying to widen the crack lines to about 3mm with a dremel/grinder, the other was saying to grind them down then lay more sheet/resin in the low spots. Both were for boats
this is on a mould on a van (the outside...cant see the cracks on the rough side)... about 4-5mm thick, cracks were caused by things moving about in the luton of the van
other pic is another bit of damage on the same mould that needs repaired too
