Today I spent my time on the Targa roof. Having quickly taken it apart in a spare hour before the car got loaded up for the paintshop, now was the time to sort it all out.
Firstly I scraped off all the old sticky caulking (like industrial blu-tack). Messy job but needed to be done.
Afterwards all surfaces where it had been got a good scrub with scotchbrite soaked in cellulose thinners to get every little bit off.
I then sorted out the underside of the roof where the headliner material is glued on.
It was covered in old impact glue residue. Not a good base to glue on top of so it had to be cleaned off. Rock hard baked old glue is not easy to remove and I found the best tool was my Stanley blade holding scraper
Working with the roof curvature (across the car, not front to back) I eventually got it all off after an hour or so.
Next I gave the whole fibreglass roof a damn good scrub wash with hard bristle scrubbing brush and detergent. This took another hour as I washed, dried and washed again until all the sand and grime was gone. Repeating on both sides to make sure it was spotless for repainting.
The top surface of the roof has a textured (splatter) type finish. Over the years this had been damaged and some sections were scraped & knocked so needed repair. With various grades of wet and dry I gently rubbed down and feathered the edges around the numerous patches of damage before re-adding the texture.
Using a bumper texture paint with a “heavy” grade nozzle in short burst to almost “spit” the paint out to replicate the original finish. The paint is specially formulated to set hard and maintain texture so it’s ideal for the job.
The top is due to go down the painters for a final satin black paint from a gun, no rattle can stripy paint jobs here!
After preparing the top I then started on all the trims and catches.
First washing and cleaning the stainless trims at the rear of the roof that holds the fuzzy “U” shape seal on. Afterwards they were polished up with brasso.
Next I cleaned all the flaky rust off the front and rear catches. The rear catches that fit on the roll bar were quite messy so ended up being stripped down to bare metal and totally repainted. The fronts came partially apart and got a clean & paint too. Finally the rear blocks that fit onto the roof and have the hooks in them that the latches hold got the same treatment.
After a quick cuppa I scraped off the caulking and sanded down the two channels that hold the rubber over the door window glass. I had a small issue when I etch primed them. Not sure what the original black paint was, but the etch just pickled it. There was nothing I could do but get the paint stripper out and remove every bit of old black paint off the two channels. After a coating of stripper the residue was cleaned off in a bucket of water with scotchbrite before hanging up to dry.
Next I got every single bolt washer and screw that holds the targa top together and detail wire brushed each and everyone until they shone. With a modellers brush I gave them all a waxoil coat before bagging up a few hours later.
Last of all this evening I gave the locks and catches a second coat before calling it a day.
