So the AMG GT3 spoiler was really bothering me. And since
@AOS- gave me the idea of just... well, fixing it, I decided to go for it.
I remembered that I have some old photoetched saws by tamiya that would work perfectly to detach the spoiler. The plastic is very soft, so it was quite easy.
Originally, I wanted to keep one side attached and simply re-glue the other side properly, but since the saw is only 0,1mm thick, it didn't take off enough material. I'd need to awkwardly sand that side away, trying not to damage anything. Alternatively. I could just saw the other side as well and work on the spoiler that way, with more freedom.
This car cost nearly 15€ + shipping.
With the spoiler off, I decided to do more work on it than I had planned initially. I sanded away the cast seams and clear coated the entire thing to protect the decals. The image above partly shows why. Admittedly, with the spoiler attached the seams aren't too apparent, but detached they're quite obvious.
The decals, being quite exposed on the edge, started coming off. Surely due to me touching them a whole lot during the removal process, but partly due to them being a bit big for the spoiler as well.
I used semi-gloss clear coat, which looks a lot like the bare plastic anyway. I re-attached it with standard cyanoactylate glue (superglue for all you non glue nerds).
Final results:
I reckon it looks much better than
originally. Not just due to better alignment, but because the decals and plastic look a lot more uniform thanks to the clear coat, which doesn't come off that well in the pictures. If you know what to look for, the glue is visible, but honestly, not nearly as visible as the plastic seam that I had gotten rid of during the process.
Since I hadn't even noticed the seam when I first got the car, it's worth assuming that the reattachment job probably isn't all that obvious either, so job well done in my book.
I know this is towing the line between this thread and the customisation one, but I mentioned the problem here originally, so posted the followup here as well.
