Default Seeking correct interior metal paint/coating source?

Hello,

It began of course, like all great projects, with turning the ignition switch and getting nothing.
I took out the battery for charging and found a mess in the battery compartment. 2 hours of cleaning and scraping down to shiny metal, and then a coat of automotive paint primer.

Could someone please assist me in sourcing the most "accurate" paint/coating products to finish this job?

Thanks in advance!

Dan

Mine looked like that. I did the scraping and wheeling and sanding , then painted with Rustoleum. I wish I'd understood the miracle of rust conversion back then.

After the coat of paint, I used spray undercoat from the FLAPS and smeared it around into a thin coat. Then I left a 100W shop light on in the compartment for a couple of days.

Kinda jury-rigged, but it seems to have worked.

I can't answer your question, which was paint code, on mine the battery cover door looked to be the same paint as the exterior but with no clear, the inner was closer to linen.

I stripped it down, used the rust converter then bed liner. To keep it neat for spray application I taped a plastic bag around and cut an access hole for the gun.

That's a great looking job.
You also have a couple of drain plugs that I seem to be lacking!

Thanks for the help.

Don't know how much the batttery well paint changed between MY '81 and MY '89. The box in mine is painted with a grey/beige'ish finish with a bit of dark 'spatter' in it. If I didn't know better I'd say it looks something like a spray-on truck bedliner material. Mine is still original so not much chance of it being actual bedliner material.

I updated the positive battery cable with some 1-ga marine cable, with swaged-on ends with shrink sleeve. I notice that your cable has one of those temporary emergency repair clamp on pieces dangling from the end of the positive stub. Exposed like that, acid fumes from the battery, especially if the battery is not externally vented (outside the box), will corrode not just the copper you can see there, but that cancer migrates up inside the insulation and does even more damage. Replacing the cable was an exercise in bending and threading it all back through the original shields, hold-downs and clamps. I spent the best part of a casual afternoon gettingeverything fit back in and dressed out to look like the original.

I only have one drain with a plug, the other 2 were open.

On the last picture I hadn't yet removed the tape from underneath to stop from messing up mu garage floor anymore than it already was.

dr bob: Thanks for the heads up on the positive cable issues, will make sure to square this away also.
wpgshark: Thanks for clarifying those "phantom plugs" in your photos ha ha...

Today I received correspondence from the local Porsche dealership parts rep:


Daniel

The coating you are looking for is discontinued through Porsche. The part number is 91109606300 and PET says it is Glassohyd 1109. That is the only info I could find on it. If you need anymore help with anything just let me know and I’ll do what I can.

Thanks

So a little more checking, and this Glassohyd 1109 goo is also used by GMC and Jeep. Maybe I'll be able to find some at some point. I'm going to check a couple of local auto body shops too. It sure would be cool to find something as close as possible to orig.... That's part of the fun!

this came up on a German board a while ago and Glasurit is the manufacturer of it.
Try this one: Glasurit ® 1109-1240/X

the X determines version, check 1109-1240/6, should come in 1 liter container, suitable for gravity feed gun, smooth version, other versions /4 are textured (require some special spray gun??).

Research and an alternative coating...

Following the suggestions of oaros (thanks!!) and the local Porsche parts guy, I looked up the tech data and MSDS on the Glasurit 1109
http://techinfo.glasurit.com/en_UK/P...109-_print.pdf
I then spent some time comparing the specs on the Glasurit 1109 with some more readily-available products. I found that several "elastomeric coatings" have properties very similar to the 1109. This includes cure rates, surface prep, and durability.

Of all things, I ended up with a gallon of "Elastomeric Siliconized Aluminum Roof Coating", white.....

So, I finished the priming and cleanup, mixed in some acrylic black to match the color in my rear too/battery area. and put on a good thick coat. Results below. Should be durable enough, I am going to add a rubber pad below the battery, a venting tube, and a new positive cable. Thanks. Dan
