Firewall and Engine Bay Detailing | Part 3

Since there's only so much that sanding alone will fix, I decided to use Bondo® Glass body filler to fill in and smooth out a few areas that looked horrible—thanks to someone at the factory using excessive amounts of seam sealer, and never bothering to make the area look halfway decent—especially around areas that are visible the moment you open the hood.

Once the body filler had cured, I sanded with 60-grit paper, and then applied a skimming coat of glazing putty, which might have been overkill since the bedliner spray will cover sanding scratches.



In order to make my life easier, I also tagged some of the vacuum hoses that were in my way. This will allow me to mask them properly and gain ample room to spray the firewall.


Bondo® Glass is reinforced fiberglass filler and is easy to use, although you only get a few minutes of working time, so working in small sections is the best approach. You just have to make sure the filler and the hardener are mixed thoroughly.





The filler creates more work, but it will make a huge difference when it's painted as all the cracks will be gone. And I also used it to cover a couple of screw holes for an even cleaner look.

Originally I was going to replace all the grommets, but I think that won't be necessary as everything should blend in nicely when painted with bedliner spray. Having said that, I plan to use new hardware, and since I will clean as much of the wiring as possible, I may choose to leave some of it exposed which, I feel, will provide a nice contrast.

Thanks for reading, and stay tuned for Part 4.
