Sandblasting Alternative? DIY Steel Hull Repair

In Wrangell Shipyard, we’re tackling the electrolysis scars on our steel sailboat Alaskan Gypsy. Instead of full-on sandblasting, we test a Monti German-made bristle blaster (scored on eBay at a bargain) that usually sells for a high price new. It promises to deliver a sandblast-like profile in a handheld grinder. Can it really dig into deep, sharp-edged pits and leave a coating-ready surface? We compare results against traditional methods, talk about consumable costs, and share next steps—whether to fill with Belzona epoxy putty or go for clad welding with 6010 rods. Shipyard life is never simple: safety concerns, budget calls, and “good enough to coat” decisions all come into play. Follow along as we work to get Gypsy back in the water.
