Priya's 79 chrome bumper conversion project
I think I told the painter I had sanded to 120 grit but since my husband asked me about it I'm not 100% sure I did mention it to him. He said put 4 coats of the 2 part high build primer on it. The instructions on the can say to sand to 180 grit and then apply 2 or 3 coats but I think I'm inclined to leave it at 120 grit and put on the 4 coats, I'm pretty sure that's going to cover it.
I think it's pretty hard to judge how good my work is unless you're here to see and feel all of it yourself. I was pretty disappointed in how my Eagle came out after the paint went on. We were in a hurry on that car to get it primered and painted and I didn't get to spend the time on perfecting it that I wanted. The car I did before the Eagle, a 75 Buick LeSabre I didn't set any deadlines and had at it until I didn't think I could improve it any more and there were no flaws in the body work that I noticed although I never severely scrutinized my work as I was nothing was readily apparent after the paint went on (unlike with the Eagle).
I want to do the best job I'm capable of and no doubt that's added a lot of time to the job. If I had it to do all over again, I wouldn't. Now with having the back end converted to chrome bumper but not the front I don't think the overall look can be any better than it would have been if I had left the car alone and just put the pace car spoilers on it, which is a fantastic look. I've been driving a rusty old Oldsmobile for the past 6 years when I probably could have been driving a nice pace car style car after perhaps only a couple of years doing just a colour change. I figure it'll still be a couple of years till I have paint on the car.
So, yeah, I wish I had just changed the colour and put the pace car spoilers on it and saved the thousands of dollars in parts and materials and years of labour. But, nevertheless here I am so there's no going back now

There was, to the best of my knowledge only one thing that didn't go right. He was building a car which, by his design, would be at the top of the class. While in process, the SCCA rules were changed, and his car was bumped up a class. That was the end of that!

In the same picture you can see a bit of casting flash on the bumper cover in the same place as the penetrating oil:
I cleaned the bumper cover again, focusing on the space between the bumper cover and the body and sanded away the casting flash that was making the gap between the cover and the body tighter than I would have liked in that area for painting the car with the cover on:
The bumper cover had a few tiny nicks and stone chips on the forward edge which I sanded off. Later I noticed that edge was sharp in places and more blunted where I had sanded (blue arrows in picture below):
I could have bought some rubber bumper patch and added fill to the blunt parts of that edge to make them sharper but adding fill to an edge is a lot tougher than adding fill to a relatively flat area so instead of doing that I decided to sand down the rest of the sharp edge so it was evenly blunt all the way along. When the car is painted no one is going to notice that that edge is not as sharp as the factory made it:
I'm hoping to avoid removing the headlight buckets for paint as it looks like a big struggle to get to the bolts holding them in place and they are nicely lined up already and I don't want to have to get them back into proper alignment if I remove them. The problem with that is the part of the headlight bucket shown in the picture below (blue arrow) which would be difficult to paint on the car and wouldn't give as good of coverage as it would if the buckets were removed:
So at this point I'm not sure whether or not I'm going to remove the headlight buckets for paint.
When I bought the car I noticed the hood was misaligned note the gap at the front centre of the hood (green arrow picture above),
You can also see the gap between the back edge of the hood and fender and between the headlight surround and the centre front edge of hood in the two pictures below:
Since I bought the car I had been thinking all that was necessary to fix those gaps was to lower the rear edge of the hood which would bring the front edge of the hood back up into alignment. Now I'm not so sure that's going to fix it. The front centre of the hood is 1/4" or more lower than the centre of the head light surround while the front corners of the hood are level to the head light surround (blue arrows in picture above).
I think lowering the rear of the hood will help with the alignment on the front edge of the hood but I don't think its going to make up all of the quarter inch or more of gap there. I can't just raise the hood at the front until the front centre is in alignment with the headlight surround because doing so will raise the front corners of the hood above the fenders. I don't know if the hood is bent or the headlight surround is in the wrong place or both. I thought about adding fiberglass to the top of the hood to make up the gap at the front but that would take a great deal of mat and resin which would have to cover almost the whole length of the hood which would be a great deal of work and would make the hood pretty thick at the front. I think I'm going to have to lower the rear of the hood and hope for the most possible rise on the front and live with the gap at the centre front of the hood that remains.

As an aside, since fastback chrome bumper cars look so good, I'm thinking of mimicking the fastback "look" with the sugar scoop buttresses, by extending them almost all the way to the rear. Going to mock them up on my parts vette and post pics.

I like the 68-73 rear with the front rubber bumper OR the chrome front end...it's unique.
Do whatever makes you happy to the front end...it will look great!
I have plenty of Crazy to spare...IF you need some............
The prior owner of my 73 added some of that rubber bumper filler when he had it painted twenty years ago.
The front bumper on mine looked horrible and that filler was cracking all over the bumper edges.
I like the front bumper on my 73, because to me it has better cleaner lines than any chrome front bumper model.
The one thing that does bother me is that the chrome rear bumpers don’t flow good when looking at the car’s lines.
I decided to replace the 73 style front bumper with a new fiberglass piece and remove the chrome bumpers, fill the holes and mold in the valance on the rear.
The guy who will be painting my car said this is something he has done many times over the years.
He showed me on a car in his shop where he welds in a crossmember directly behind the rear valance which supplies the same protection as the bumpers and brackets would in a rear end collision.
I can’t wait to see what you do next!

I've been also thinking I could take the hood off, add mat and resin to the undersides of the front corners and then shave them down from the top. The only thing with that is I don't know where I'd put the hood, there's no room in the garage to put it without having it on it's side. That was a hurdle on doing the chrome front end too, I know the 68/69 front clip would have to come off and on the car several times and I didn't know how I could do that with no were to put the front clip when I needed it off the car.

Check out Stinger Fiberglass Design/American Sports Car.
I purchased my new hood and fiberglass front bumper from them.They manufacture the fiberglass pieces for most of the vendors, their quality is flawless and they have been in business for decades.
They offer several different front bumper design’s and spoilers for C3’s.
If I remember correctly they also have a Pace Car spoiler.
