Welding in the Miata Rocker Panel – MX5 Miata Rust Repair Pt. 4


Hey, what’s up, this is Pete and welcome back to underdog garage We’re now into part 4 of our Miata rust repair series and we are finally getting to weld in our new Replacement rocker panel on this mx-5 Miata. It’s definitely been a really challenging process It’s definitely stretched my abilities, but I think it came out pretty well And I think it’ll be pretty valuable for you especially if you are tackling this repair yourself, and if not, It’s pretty cool just to watch some good footage of welding and metal going on metal So with that said, let’s go ahead and get into this install of this new replacement rocker panel First I needed to figure out which parts of the rockers panel I had to trim off to get the perfect fit after a couple test fits. We were ready to start trimming the panel I also made some adjustments on the body to help it Since the inside of the rocker panel won’t be accessible. I sprayed rust converter to try and neutralize some of the remaining rust I can’t get too The car body ready it’s time to prep the patch panel I grind back the paint on the areas of welding I’d spray any excess bare-metal spots with weld through primer One final check on fitment and it’s time to weld I started in the center and worked my way outwards in a circle with the wealth This panel is so big. I wasn’t really concerned with overheating and warpage I moved to different areas of the panel to keep the heat less concentrated in one area You know when you’re first putting the panel on like you’re just thinking to yourself holy crap like thing actually gonna work So it’s actually working and looking like actually part of the car and it’s just a such kick-ass feeling a Couple sections on the front and back Required but welds so I attack them in place first then ran a bead after between the tacks Once all the welds are finished I ground down any excess filler for a smooth finish and cover the bare metal with well through primer Inside the rocker panel, I sprayed fluid film This stuff helps to prevent corrosion and future rust as it coats everything in a wax film All right, so we’ve gotten our rocker panel fully installed everything’s welded in There’s a couple things I have to go back and touch up on some areas to prime and I need to put some seam sealer Down in some areas to prevent water from getting inside the panel one thing I did want to point out is because I didn’t get a chance to film it on the underside of the rocker panel where the panel meets the unibody structure I ran seam sealer all along that edge because it kind of has a lip and could collect water pretty easily especially if there’s no Preventative material there. Other than that this panel is pretty much in in part five We are going to be installing the quarter panel and we’re going to get this repair completely finished and the car ready for bodywork All right, that’s it for this episode.
