Filling Holes Without Welding
it was at this point i figured, man, i'm bout to paint this thing anyways so i might as well take it a step further.
In a perfect world i would cut out little metal circles, use a magnet to hold them in place and then tack weld them in etc..But i don't have a welder here. I used this stuff on my Lexus when i had to fill spoiler holes in my trunk. You basically put it on the inside of your panel and it gives your bondo something to adhere to. Otherwise your bondo is just going to droop into your hole.
So i cut pieces that covered the holes. (it has adhesive on the metal grate)
I scuffed the mtal and degreased it then stuck it on both sides. You can see it if you look close up under that hose
view from the top
both holes slightly coned and protruded like a boob so i used a big hammer and very lightly bounced the hammer aroundthe edge of the holes to flatten them. this was before i did that
sanded around the holes and degreased, then mixed up some good ol body filler and covered them up
But then it was Thankgiving and i had to roll this dismantled Denali all the way out to Phoenix for a get together.
Here's a pic in Gila Bend (half way to Phoenix)
