Replace a Gutter Corner
1. Grind centering holes in the coroded rivets with the #945 grinding stone. Next, drill out the rivets with the #150 drill.
2. After removing the old corner, clear away the old sealant with the #121 high speed cutter.
3. Position the new corner and drill holes for the pop blind rivets. When drilling, try to use the same holes from the old gutter corner.
4. Use a pop blind rivet tool to install new, color-matching rivets. Then apply sealant to the joints (sparingly) so water doesn't become trapped.
