Trainees trying out for Navy Seals have to endure something they call "Hell Week".
I am in no way comparing myself to those tough SOB's, however I've been going through my own "Hell Week" here myself.
So, in the week since my last update I've started in on the filler work.
In a big way.
I'll get to the pics and descriptions here in a sec, but I just wanted to say this first:
Having the AstroRoof stamped in the middle of the roof has sure had some weird effects on the straightness of the roof. This roof is wavy as hell, and very little of it is or was related to my repairs. In fact, this roof has more waves in it than a Hawaiian surf competition!
😕
There are strange high spots in weird places, and the edges around the AstroRoof opening are much flatter than the surrounding areas. This all adds up to a very challenging surface to try and get perfectly flat and straight.
I attribute it to the poor stamping practices of the time, I can think of nothing else that would create these weird characteristics. I can certainly see why they painted this one white and slapped a vinyl roof on it. Far cheaper to cover up all the sins than to try and fix them/make them acceptable.
As for my "Hell Week", it's been just that. In the last week I've created and eaten/breathed in more dust than I care to admit. It's hard work blocking out such a large flat surface, I've been drinking nearly an entire 2L bottle of water every time and sweating most of it back out again.
In the mornings I ache. Everywhere.
The back from leaning over at weird angles, my arms from the long blocking strokes, even my legs from keeping my balance on step stools and the floor inside the car.
Anyways, you get the point, so I'll stop my complaining. It's hard work.
It took me 4 full days alone to get just the large flat area of the roof from the back window to the AstroRoof opening blocked out and straight, and finished in 120 grit.
I started off all the filler work by filling the roof seams with short strand fibreglass filler and blocking them out, but I didn't see the point of taking any pics. It's just the foundation before body filler anyways. You can see them done in some of the following pics.
This was the first full application of filler on the roof:

And yes, I know what you're thinking.
"Damn D, that's a LOT of filler!!"
And you'd be right. But before y'all start flaming me for having a "bondo bucket", or other such terms, this is the correct way to do a large flat panel.
A common mistake that many novices make is trying to fill many small areas and sand each one individually. This doesn't work, this just creates waves in the final product. You have to skim the ENTIRE area, then block it all out as one. The filler will stay in the low areas, and will get removed from the high ones.
As bad as it looks to have that much filler spread across the roof, keep in mind 90% of it gets sanded off and ends up on the floor. In fact I've become very proficient at turning large quantities of expensive product into worthless dust!
Lol
Anyways, back to some pics. Most of these are just "in progress" pics, usually taken at the end of a fairly substantial step.
These were after the above application was finish sanded in 40 grit:

As you can see, it creates quite the mess!

After that step, the area was blocked out in 80 grit to remove the 40 grit scratches, but this left the area slightly low.
Time for an application of glazing putty. The putty serves several purposes, it fills any pinholes in the underlying filler, adds a thin skim coat, and provides a finer, smoother easier sanding surface prior to primer.
Again, ya gotta skim the whole area:

The masking paper covering the back window is to keep any drips or spillage from getting into the window channel areas and off the window itself. The putty is quite a bit more runny than the filler, so I didn't want to take any chances.

This is the back part of the roof now completely blocked out and flat, finished in 120 grit.

It still looks thick, but as you can tell by the bare metal areas, it's actually pretty thin. I can't sand any more off, or I'll get into low areas and will create waves. It took 4 days just to get to this point.
