My first time: Bodywork, Wet sanded & Polished (tons of pics)

I am finally getting around to posting pics of some of the work I did over the winter/spring (and part of summer :lol:). I bought a used hood that had the corners damaged and set out to repair it with fiberglass. I had never done any kind of body work in my life, nor any fiberglassing.

So I did a lot of research and set out by starting to make a mold for the fiberglass to rest on while it hardened. First, I had to grind off all the broken glass until I hit the good stuff, creating as much as a feather-edge as possible to create the largest possible surface for bonding.

Then I laid 5 layers of mat to make the basic shape and let it set over night. Fiberglassing is actually pretty easy to do but is intimidating at first.

Then I ground down the access and kept refining the shape. I had to add some more fibreglass and got closer to the shape. I traced the ends of the stock hood onto a piece of cardboard and then used that as a template to make the basic shape. Then used a very thin layer of bondo to refine it.

I mounted the hood and discovered that along the each side of the hood where it met the fender, the fender stuck up about 1/4" along the whole sides (no pics though). So I then used short-strand fiberglass bondo on both sides of the hood and block sanded it until the shape was perfect. I block sanded the rest of the hood to get out all the waves and imperfections made in molding process of the hood. I then block sanded the bumper and both fenders (fixed a few dents too).

I then had the front end painted. Well after painting, there was a lot of orange peel and some runs, but I expected this because 4 heavy coats of clear were added on top of 2 layers of base. I couldn't stand the orange peel so I wet sanded the entire front end and then decided to wet sand the rest of the car. I started with 2000 grit first but then realized I should have started with 1500 grit to help speed up the process. Wet sanding took balls for the first time and I was also afraid of ruining the stock paint (because everyone says its thin) so I wasn't as aggressive on the back half of the car. Wet sanding took many hours and sore arms. After standing back and seeing the completely dull, I started to wondered what the hell I was thinking!



You can see the orange peel in the lights

So I started polishing (another thing I had never done in my life). Polishing was a lot of trial and error at first to see what worked. I started out with a Porter Cable (Optimum Compound with an orange foam pad) and quickly realized that no matter what combination of polish or pad I used I was never going to get the 2000 grit sanding marks out with the PC. So I borrowed a Makita 7224 rotary (another first, and you read/hear about all the horror stories with rotaries) and started polishing with a wool pad and Optimum Compound. This started producing results. I then started mixing 50/50 with Optimum Polish which really finished nicely and saved a lot of time. I then switched to a Lake Country white pad and Optimum Polish with the rotary @ 1000-1200 rpm and the shine was starting to really come out. This was basically my last step.

For my last stage protection, I put on 3 coats each of Zaino Z5 and Z2 with Z6 between each coat. And as you can see these are the results. I am pretty happy with results for being the first time doing body work, wet sanding and polishing. However, I think I should have gone one step further with a black finishing pad and glaze or another polish like the Manzerna (which everyone speaks so highly of). Black shows every little flaw.

And of course I have the car clean for one day and the very next day it rains.

You got big b@lls to try what you did! and my hat is off to you! Awesome work for you to attempt this your first time!:2thumbs: :2thumbs: :2thumbs:

My bad, i should have elaberated a bit.



Sorry, I should have too. SMC = Sheet Molding Compound. That is what they used to (still do?) make Corvettes from. I'm not sure I remember the exact process, but the SMC is the "raw material" that is put into a die and formed in sort of a similar way to how a metal part would be formed. Hand layup is too time consuming for a production vehicle, although since I have seen composite tape-laying machines for aircraft parts, who knows what they do for cars these days.



At the risk of exposing myself to ridicule, I will reveal that in the 80's, I bought a used '82 Chevrolet Citation X-11. This car had a High-Output 2.8 V6 (135 HP!) with a functional cold-air intake hood scoop. This model-specific hood was 'glass, perhaps to reduce the cost of tooling based on lower quantity or difficulties with the shape of the intake (or perhaps for weight). Interestingly, I had paint problems on the hood, perhaps for the same reason some of us currently have problems with CC failure on plastic/composite mirrors/spoilers due to the much lower thermal conductivity of these non-metallics.



Interesting how GM changes things between different models of the same car, I found out my current GM has an aluminum hood and trunk, which I suspect was done as a weight reduction measure based on a particular option package...or perhaps they are all aluminum.



Sorry to have gone off-topic...
 
That is one hell of an amazing job you have done there :bow :bow There is such a big improvement on the orange peel and the car looks fabulous in the after shots :goodjob .
