Default Proper way to shave spoiler holes-A DIY

I've seen a lot of threads on here about people "shaving" their spoiler holes with stickers, screws, epoxy, etc. While I'm not one to denounce the methods of others, I thought it would be good to show one technique that I found to work the best...welding.

Materials:
Welder
Angle grinder with 36 grit roloc
Auto body filler
Auto body glaze
Sand paper 36,80,180,220,320,400. Long board and DA style
High build primer
Self etching primer

First grind around the perimeter of the holes that will be filled.



Next, put your welder on the lowest setting to avoid overheating and distorting the metal. I know some of you will say "I don't have a welder". I'm sure in your circle of friends somebody has to own one, even a flux core welder will do. If not, go buy one. To fill the holes I use a technique called "spider webbing". Basically start on one side of the hole and bridge your way across with weld. For the larger key actuator hole I placed a piece of metal behind the deck lid, and then filled with weld.





Work very slowly when welding sheet metal. Weld/pause/weld/pause. I always wait for the prior pulse weld to be cool to the touch before welding again. Yes, it is a painstakingly slow process but will save you a bunch of time trying to straighten the heat distorted metal in the long run.

Then grind all your welds flush. I used a 35 grit roloc on an angel grinder. Grind slowly working area to area trying not to heat the metal too much.

Now it is time to apply filler to remove any inconsistencies in on the surface, I prefer to use "Rage Gold'. First grind down the work area with 80 grit sand paper on a dual-action sander. Use the sander flat and you will slowly start to see the different layers of paint/primer.



You will need a flat, non-porous, surface to mix the filler on. Everyone has their own techniques when it comes to using filler. I like to apply a good amount on my first coat. This first coat is where the majority of the "fill" should come from. Use a spreader to put down as much filler that is needed to fill the welds and overlap surrounding area. Let harden, and then begin to sand with 36 or 80 (depending on size and depth of work area) grit sandpaper on a block. Sand in a diagonal pattern // then \\ crisscrossing and creating an imaginary "X" over the work area. Do this until you level the filler with the surrounding metal. This will take some practice to get correct. A helpful trick is to apply a guide coat of black spray paint to see if there are any low spots or high spots in the filler.

Continue this process of applying filler and then smoothing, and after every coat go to higher grade sandpaper. (80,180,220,320,400). Stop when you feel, with your hand, that the surface is level with the surrounding area and there is no bumps, or dimples. You will finish the filler with 400 grit before applying the glaze. Glaze is basically used to fill any fine scratches still left in the surrounding metal from sanding, or pin-holes that are in the filler. You will apply this extremely thin over the filler with a decent amount of pressure to fill any imperfections. Let the glaze dry and sand with 400 grit using the same process as before, but not so much that you start to take off material from the filler below. You will see the glaze fill the scratches and pin-holes.

Now sand the entire work area that you will be priming with 400 grit sand paper. "Feather out", sand any lips from the various layers of paint to make sure there are no ridges that will be visible when painting. If you can feel it with your fingers you will definitely be able to see it when it’s painted.

Mask up for high build primer by back taping your work area and covering anything you do not wish to get primer on. Never apply primer to the edge of the tape or you will get a "hard edge". Apply "self etching primer" to any bare metal. Then use high build over the work area.





Let the primer dry for the recommended time, and wet sand with 400/600 grit paper. Use the same X pattern over the whole area. Be careful to not sand through the primer.

Then send it to paint:



Wet sand:



Then buff:





Any questions or clarifications feel free to ask.

Great post! Thanks for taking the time to show us all. All I have is a flux core but I tell ya what, if done right you can weld almost anything you need.

My only issue is the painting. Need to get a HVLP setup after the new year and force myself to learn.

Thanks again.

If you're going to weld the panel on a Subaru using GMAW (MIG) or FCAW (FluxCore) be sure to use the smallest filler wire. That is: .023 for GMAW. Do not think .030 wire is close enough. You WILL warp the steel using .030 or get no penetration at all running your voltage too low. No penetration means the metal you just added is sitting on top of the other metal. Might as well just set a coin on there.

Those who know how to weld (should) know how to do this. He did not state in his post that this should be your first welding job with a Lincoln Job-Pack, lol. But you are right, you need to now what you are doing.

Exactly! Picked up my trunk last night and it looks even better than it does in the pictures! Not to mention knowing that the job was properly done and will last me for the life of my car is really reassuring! Matt really knows what he is doing and talking about when it comes to body work and I wouldn't hesitate to contact him with any job of that sort, big or small.
