Hello again and happy New Year everyone!
I'm well aware that it's been quite some time since my last update and I apologize - that's not to say that I haven't been busy on the car, quite the opposite in fact.
There's a saying that says "80% of the work takes 20% of the time, but the last 20% of the work takes 80% of the time...".
Nothing could be closer to the truth in my case when it came time to wrap up some of final details on completing the composite headlight mod. The bulk of the heavy modifications to the header panel actually went fairly smoothly and quickly, but as you'll see making the modifications to the headlight bezels and getting them and the grilles to fit well was time and labour intensive and took a REALLY long time.
🙁
So that's what I'm covering in this particular update.
This may seem like it's going to be another of my long updates, but actually most of it will just be lots of pics. I'm going to do this in a step by step format so that it can be seen what was required to achieve what, in the end, appears to be a really simple result. So hang on, and here we go...
Ok, first off, you may remember that I got my ballasts, transformers, and bulbs for the HID kits already installed. This wasn't simply for kicks and looks, it was actually so I had the proper and final bulbs in place to be able to accurately aim the lights. This was step one as the final bezel shape needed to be based upon the headlights properly positioned and aimed. Once that was done, the bezels and grilles were de-chromed at my local chrome plating shop. They DO NOT chrome plate plastic unfortunately (more on this later), but they do have the ability to remove existing chrome from plastic parts with a simple chemical bath. Once my parts were stripped and I had them back, I was ready to start the process of modifying them to fit the new lights. Here's what I started with:
Before I could even start to rough fit the bezel, the center bar needed to be cut and removed. I tried a multitude of different methods to cut the plastic, but just a simple fine toothed hacksaw blade (removed from the saw itself) seemed to work the best. Here, the center and a small amount of the upper flange have been removed:
Even with this removed, further trimming needed to be done to get it closer for a test fit. The biggest area of interference at this point was actually the top portion of the bezel. The angle of the "roof" portion was too great, and hit the top of the light preventing it from fitting. So pencil marks were made on either side as cut lines to follow, and another line was scribed along the leading edge with a compass to outline the offending area. Note that I stayed well away from the corners on my initial cut - it's always easier to remove bits at a time than it is to add material back in.
The bezel that I'm working on in these pics is the driver's side, in this photo you can see where the upper portion was removed.
With that done, I was getting closer, but now the same area needed to be trimmed from the lower portion. The marking and trimming processes were repeated the same way.
Finally, with the largest areas that were causing interference removed, I was able to get to the point where I could physically fit and attach the bezel in place around the light with the mounting screws. As you can see, still more trimming was needed particularly in the corners...
...so more marking, trimming, filing and fitting was done until I had gone as far as I could with removing existing material. In determining where the radiused corners needed to be in relation to the black "gasket" around the new lights, a fine file was used to work it to the desired shape.
With this filing and fitting process repeated until all four corners were close, it was time to start adding material back in to make it look right. First to get addressed were the two slots on either side that were originally used for the factory sealed beam light adjustment. The slots and the surrounding area was sanded with 120 grit to rough up the surface and provide some tooth for the repair compound to stick to. Once that was done, the back edges of the sides were back-masked with 2" masking tape to create a "dam" for the compound to stay where it was needed.
Some of you may have heard or seen me recommend and use this product already - but this is what I used as a "filler" if you will on these parts. 3M 8235 Semi rigid plastic parts repair. It's suitable (and recommended) for use on ABS plastic parts, which is what these bezels are.
This is an excellent product, however, it has an EXTREMELY short work time - only 50 seconds! Yup, better have your sh*t together before you dispense this product, or it WILL set up on you and become unworkable before you can blink. With that being said, there's obviously not much time that can be spent on smoothing it out and making it look all nice n' purdy. So now you'll understand why it looks so rough and crappy in the following pics. It doesn't much matter anyways as it all gets sanded out afterwards.
