Fiberglassing help

Does anyone know if I can just glass ontop of the black deck grip?? It looks like some sort of paint with silica. I need to level off some large cut outs in the deck, and can't for the life of me seem to remove the black stuff effectively. Was thinking of roughly leveling the holes, then laying up the whole deck?

Thanks in advance

That's what happens when people use sand as anti slip in their flow coat,you can't do anything with it
Far better to use plastic grains or if you don't want to buy then sawdust works too and you can get them off when you need to
I did one last year and used a 9" grinder with 36g sanding disks across the whole deck used a few disks but got there in the end
If your going to be attaching anything it should be ground back to clean glass if it's just cosmetic then a layer over the top may be OK to bury the problem but you do run the risk of it lifting in time as it won't adhere as it should

Yeah it's eating discs, used about 10 30grit clearing the sections you can see. Only a 6" disc though. It's cosmetic mainly and I've got new deck paint/grip to go on. Just want to make sure it's all nice and level. Maybe just have to suck it up and graft till it's gone 😭

I was the same with mine but I just took the view that once it was done it was gone forever
It's a horrible job I was like a snowman after mine
Best of luck with it!

tom use a steel grinding disc that will shift it on a 4" grinder i did mine 6 m boat but make sure you put some carpet over the tubes just in case you touch, be generous with the new flow coat to fill in the dents if you do use gritted flow coat use a small grit as the big stuff is too aggressive on the skin and kit IMO

cheers
