8. Cut using an appropriate power tool. Gelcoated fiberglass siding can be cut using a jigsaw with a scrolling blade, a small hand-held circular saw with a plywood blade, a spiral saw with a heavy duty tile bit, or a 45-degree angle grinder with metal cut-off blade. Use fine-toothed blades with carbide tips. Garner the world to be removed as dwarf as viable, on the other hand beyond the damage. Practise the incision square in shape, now eventual repair Testament be easier.3. Sweep the duty globe to remove any loose info.
