Hi Gary,
thank you for help with color codes. I looked in my log books and didn't find any record of any paint job, so I still think that it's the original paint. The blue colors have plenty of chips and nicks but somehow they look fresher and shinier then the white. I will take better pictures and will check if somebody on GG will recognize the colors. If not, I will have to trust the paint shop guy.
I have put 2 spacers on the top right mount and 2 spacers on the bottom right mount. The left mounts have one spacer each.
I started saving my installation notes on Bondline:

When you get a chance, please take a look. I would like to know what you think.
Thank you,
-Boris

Hi Boris,
If the white is still the original 817U, it will buff out nicely. Odds are, if the blue is still shiny, it's been repainted.

The colors on the 70's era Grummans are RM Centauri Acrylic Enamel. It's not baked on.
Also, the colors are not custom colors. The orange, for example, is the orange from a 73 Volkswagon. The metallic brown is from a Dodge or Plymouth of around the same year. I'm sure if you take your ELT cover to an automotive paint store and try to match paint colors from 73 on, you'll find yours.
Also, DuPont has totally revised the paint codes for paint sold in California.
So, the numbers may not match up. Most paint stores have the old codes though.
So, tell us, how's the installation going? How many shims on the engine mounts did you need?
Gary

How was the alignment to your original cowling before you started? How much changed with the installation of the Jaguar cowling?
Boris wrote: "Rivets to attach the upper cowl halves to the hinge - cherry-max countersunk head 1/8". 38 rivets - 19 on each side. Install manual asks for CR3212-4-2. According to Aircraft spruce <https://www.aircraftspruce.com/catalog/hapages/cherrymax.php> those have grip range 0.63 to .125. I measured hinge thickness + upper cowl thickness = 0.142". Maybe CR3212-4-3 is better? Ordered CR3212-4-2 anyway. Those require drill #30, Aircraft Spruce part 12-04217 and #30 countersink, Aircraft Spruce part 12-00880. The cage for countersinks is Spruce part 12-00940. "
- - - - This is a gray area. The layup procedure calls for extra plies along the hinge attach. In theory, the hinge line has a thickness of about .055 to .060 inches.
Boris wrote: "Nutplates to hold lower cowling halves together. 9 on the bottom + 3 on top. There are also 2 to hold upper cowling halves to lower cowling. Total 14. Install manual asks for MS21048-L-08. I believe Manual says 'countersunk' by mistake. I found those on www.cessnadirect.com. AircraftSpruce has MS21047L08. Aren't they the same? "
[b]- - - - The difference is the MS21048-L-08 won't rust.[/b]
