Bale original roof at donor roof naka spot welding. Nag hire ng latero/torch para ma remove (?). Tapos final PU glue ang gamit. Naisip ko iyong strength ng dikit iyong weak point iyong in between na paint layer. Pero since PU paint din ang paint, same binding strength din ng PU glue?

Suwerte at malaki ang space sa work garage, plus may nagko-color match din ng custom spray cans.

Na suwerte pala kami sa 2000 Civic LXi namin. Nabenta last 2019 with original paint intact (except rear bumper). Taffeta white naging bone white after 19 years hehe. Smooth naman roof aside from normal paint wear.

Straight forward din mag tanggal-balik ng ceiling liner? Kailangan muna yata maalis ang windshield para mailusot ang ceiling liner. Magandang oppurtunity mag add ng roof insulation/heat shield.

Here's the sum of the work done...
Strips were around 7.5k, front & rear. No tinsmith hired though, spot welds on stock & replacement were just drilled loose. Absolutely no heat, gas nor rod welds done. All drill scars were primed w/ PU paint. Do It ColorLab compu-mixes OE stock paint codes & cans them for DIY rattling or pro spraying.
Windshield removal & reinstall labor was 4.5k. Headliner was DIY removed w/ extra care & clean gloved hands prior to glass removal.
Roof bones had no welds both old & new. The cancer was caused by wrong, corrosive twin-sided adhesive strips used by Honda Ph assembly. Nippon donor had zero rust.
PU has long been used in automotive panel joinery. New roof to car frame had PU in between all joint lines & rivets holding for good undisturbed cure. I've had spoilers installed w/o drilling....just trusty PU.
Adding extra insulation, that's a good idea, but just went w/ putting it back up to stock specs.....except the welds which would've required pro painting & more spending.
Hope this helps anyone who might Civics having the same problem. Very DIYable w/ planning & courage.....Pardon the long post.

BMW CF roofs are attached w/ no welds. We've used PU for various applications that require long term watertight seals. The documented & shared pics above were the general process. Stock & new scalps weren't full-welded, just spots along the front/rear top of windshields & along the 2 gutters. Both patient & donor roofs relied on factory PU joint sealing, not welds for watertightness & structural joinery.
