bulletin explains various techniques for making sunroof installation possible and relatively easy.
Similar height ribs may interfere with a sunroof install in the Jeep Liberty, Chevy Astro, GMC Safari, and in the rear
sections of many full sized SUV’s.
I. Metal Frame Sunroofs
In order to accommodate the added thickness of the ribs, longer clamp frame screws or peeling one score off aclamp frame may be required.Install as normal, with any of the following options:
A. Use CS-105 (3/8″ x 7/16″ D-shaped foam seal) as main frame sealant
1. Measure and cut sunroof hole as usual
2. Apply self-adhesive CS-105 to sunroof frame (approx. 9 ft. per sunroof).
3. Join CS-105 ends at a 45° angle (not a butt joint). Apply sealant to the joint.
4. Clamp sunroof into hole as usual. No cleanup is required
B. Use non-corrosive silicone sealant to fill between the ribs.
1. Measure and cut sunroof hole as usual
2. Apply a bead of silicone in between the ribs to fill the gap
3. Apply a bead of silicone to sunroof frame (in place of butyl or foam tape)
4. Clamp sunroof into hole as usual. Longer screws may be required on some sunroofs.
5. Cleanup is required. Neatly smooth and feather the silicone around the sunroof frame.
NOTE: shims can be helpful, but are not required – metal frames will not twist out of shape
