Great job...looks like a lot of hard work.

My first Nova was a 1970 Forest Green L78...bench seat/4spd.

Nice work, and thank you for posting and documenting all this.

I hope you don't mind if I go back a few pages and capture some questions:

What is this "old JB Weld trick" of which you speak?

Do you all know if these little posts are available as a repair?

My Chevelle is missing a couple, apparently from the factory.

Yes - had to replace a few on my Nova ... I'll have to look at my records and see where I got them from ... Craig

They are available from Classic Nova (pop rivet style) and SS396 (screw in style)

wvhylander 10-14-2022 01:09 PM

They are available, you need a stud welder and the appropriate end to install them. They’re a couple YouTube videos out there.

If a window channel is pitted up in some areas (but no perforations) a guy could use all metal filler or something like JB weld as a filler layer to smooth it out. If it is sanded out and sealed over with paint you will be able to get an adequate seal to the butyl for glass install. (It is more durable and water resistant than bondo but not a great repair for larger damage)

Miscellaneous bits
Everything was sprayed in the same session using three booths.
Two coats of clear, allowed to dry a couple days, sanded open, allowed to gas off for a couple more days, then resprayed with two more coats of clear.

I wanted to used House of Colors clear for this job but was talked out of it by the shop owner.
He suggested their Sikkens production clear for reasons that they have everything available "IF" something were to go upside down. Plus painters are familiar with it and there would be no concerns with compatibility to the base.

It turned out awesome and the Sikkens is a great product. The choice did however come back to bite me in the color sanding and polishing process.
I'll get into that in the next chapter of the Green Bastard !!

Ya, it's a looong road. Big project for a back yarder like myself but I normally don't put deadlines on so I just enjoy my pace (and wait on parts).

That said I just entered it for the local March 2023 car show so now it's hammer time !! (It is currently a roller again, will catch up on the posts).

Then MCACN 2023 ?!?

These are what I used. I didn't have NOS quarter panels installed so I could drill holes in them for screws. Some folks will use the screws and seal them with urethane. Didn't like the idea of possible water intrusion around the screws.

Well once you've spent hundreds (cough cough 1000's ?) of hours getting the body as straight as you can and having it painted what any insane person would do is start sanding it for polishing :eek:

Most of us know of the typical flaws of dust, drips, runs, orange peel can be reduced or eliminated with polishing. This clear was applied in two fairly heavy coats, scuffed and allowed to "gas off" for several days then hit with another two heavy coats. With the specific purpose to have good thickness for sanding and polishing. The part I didn't know is, this particular production clear (with surface additive) is not very friendly to sand or polish.

The sail panels had about the worst orange peel, the light reflection and angle here makes it appear exaggerated and very obvious. (I had already started sanding the side of the quarter)
Attachment 228683
Similar surface finish on the trunk appears much better at this angle of view
Attachment 228684
And the lower rocker area... the reflection in the red box area shows the surface imperfections which were pretty consistent on the whole rocker but show up more in the right reflection.
Attachment 228685

I was STRONGLY advised by the paint shop to not go more aggressive than 1000 grit to start (we'll get back to that later). For most areas I use this aluminum block wrapped with wet/dry paper and use a spray bottle with a couple drops of dish detergent for lubrication and to clear the sanding residue.
Attachment 228720
This is the same rocker area after a first pass with 1000. You have to make many rounds sanding, wiping and drying off to watch your progess. The high spots show up as dull (sanded) and the low spots remain shiny. You have to be VERY cautious around edges. You can see on the door... I have stayed away from the body line with the coarse paper. The paper will cut aggressively across corners and edges so it is easy to cut through the clear.. then it would require repainting. As soon as you cut through the clear the base color will also require repainting. Experience, experience, experience... I have watched many and learned (and burned though before). You have to be careful and patient with the sanding... it is easy to sand out a low spot if you cheat the paper and dig in an edge of the block. You need to be very consistent with holding the block flat against the surface and checking progress often. You can't see anything when it is all wet. And just like with bodywork the straighter and flatter you get it, the longer it takes to remove material.
Attachment 228721
The top of the drivers door had a couple of heavy runs which I first scraped down with the flat (90 degrees to surface) edge of a razor blade.
Attachment 228722
Then further sanded out.

The desired result of the sanding is to achieve a perfectly flat surface in preparation for polishing.

Here's where things get interesting... After sanding every square inch with 1000 grit, You have to follow up with ;
1200
1500
2000
2500

The first grit is the most time consuming because you have to remove the surface defects and the following grits only have to remove the previous grit scratch however....
You can understand where the hours start to pile up.

After 2500 I also quickly orbital wet sand with 3000, 5000 and 8000 to cut down on polishing time (arguably ? as most polishing time is spent removing stray coarse scratches which the orbital grits would not cut out)

Being that the paint was fairly fresh (only three months since sprayed), I worked the sanding around the entire body for each grit allowing further time for the paint to gas off (evaporating out the solvents). As you get to the finer grits some shine begins to come back.

Attachment 228909

Attachment 228910

As I began to coarse polish, the Green Bastard reared it's ugly head again. For starters this paint was a Bear to bring up (get the shine back) and work out the stray scratches (I believe that was mostly resultant from the additive but this is a production type paint so not specifically formulated for polishing) I was working my way around the body and I noticed when I looked back at the first area completed it seemed to be not as nice as when first finished.
Note the "bumpy" look of the light reflection. (the reflection doesn't lie!)
Attachment 228911
So I went back and resanded an area that was first completed. :shocked:
Back to the drawing board... The best we can figure (along with the paintshop guys) is the paint was not yet fully cured. Due to the heavy application we think the drying process (cross linking) was actually still moving the surface around. This panel had been fully sanded out flat and polished out about 3 weeks earlier.

Attachment 228912

Attachment 228913
So... change in plan back to MY "normal" routine. Firstly start with 800 grit ! So I picked one area and re-worked it until I was satisfied.
The reflection doesn't lie !!

Around this same time I was helping out a friend with his 70 SS 454 Chevelle.
The car had previous damage on one door that was poorly repaired.... and it bugged him bad. I stripped and bodyworked a (very solid) door for him which he sent out for paint and returned to me for polishing :smirk:

Sanding and Polishing time start to finish for this door was about 8-10 hours.

By comparison, a Green Bastard door probably took me 30+ hours !!Attachment 228915

As for counseling, I think many of the people on this forum who strive for perfection and date coded/NOS parts need counseling..:grin:
