Step 10. Epoxy. Wear some rubber gloves, have alcohol and blue towels handy. Get your epoxy gun ready. Install mixing tip. Reinstall cap to mixing tip to secure it to epoxy tubes. Lay down an 1/8” bead of sealant around the entire perimeter of the roof frame and drip tray. If you have holes from completely drilling out the spot welds, make sure to go completely around the holes. NO EPOXY GOES ON THE ROOF FRAME CROSSMEMBERS. PERIMETER ONLY. Spread the bead of sealant around bonding surface.

This body panel adhesive is unique as it has glass beads in the adhesive to maintain correct bond line thickness (keeps it from being squeezed entirely out). This epoxy has a 45 minute setup time and a 4hr hard set. Cure time is a full day. Plan on getting all your epoxy laid and positioned in 10 minutes and your roof clamped into place in 10 additional minutes.

Lay the roof on and locate it to your marks. Work hastily to ensure that it is centered and not crooked. Once you have it where you want it, clamp the center of the front lip. Then clamp the center of the rear lip. They do not have to be super tight but snug enough to squeezeout sealant from the bondline. Start working your way around clamping up the front and rear lips. At a minimum you need 4 clamps on each lip. Lay down microfiber on the left and right side of roof right n the center. Place large heavy things on the microfiber to help squeezeout the drip tray bondlines. I used small tool boxed and paint cans. Maybe 30lbs each side. Walk around and inspect squeezeout along driptray. Repair any area that mis missing sealant. I followed up mine and placed an additional 1/8” bead along the driptray to carbon panel interface. I don’t think it was necessary. Take your rag and go along the underside and wipe any epoxy drips.

Take your clips from step 9 and glue them down to their pads to mimic OE location. Use a piece of carboard and squeeze a quarter sized dot of sealant out onto it. Dip the clips in the epoxy and squish down on to the locator pad. Press down with a good amount of pressure to ensure good bondline and squeezeout. Roll the car out into the sun and let bake for 4hrs minimum. I waited a day before popping the clamps off even though the epoxy was rock hard after 4hrs.
