Bump-outs are made from hand-laid fiberglass, so minor contour variations and small dry-fit gaps can occur. Check the panel alignment and bonding-flange contact around the perimeter. The finished installation needs a continuous adhesive bond with the thickness specified in the installation guide; do not squeeze the adhesive down to zero thickness. \u003ca href=\"\/pages\/window-installation-instructions#bump-outs\"\u003eRead the bump-out installation guide\u003c\/a\u003e before cutting or bonding.\u003c\/p\u003e\n\u003ch3 style=\"font-size:18px;line-height:1.4;color:#18354e;font-weight:650;margin:24px 0 10px;\"\u003eHow can I clamp the bump-out during installation?\u003c\/h3\u003e\n\u003cp\u003eA little preparation makes installation easier: dry-fit the bump-out and have your supports and clamps ready before applying adhesive. Padded C-clamps can be used from the inside where accessible, and suction clamps can help hold the front portion of the bump-out from the exterior.

Protect finished surfaces, maintain the adhesive manufacturer's required bond-line thickness, and use only light, even pressure. Clamps should support a properly dry-fitted part; do not use them to force a poor fit, squeeze out the adhesive, or lift the bump-out.
