Reading some German sites on the issue of that illusive aluminum based anti-seize, Optimoly-TA, it appears the stuff can be had at BMW motorbike and Mercedes Benz dealers... probably for less than a Porsche dealer would charge for 100g tubes.
However, if its really needed isn't clear. I and most folks, I think, have been using standard auto-zone'ish 'anti-seize' paste to install spark plugs into aluminum cylinder-heads for a long, long time without issues about bimetallic corrosion, as far as I know. Otherwise, there would be a supply of paste use in aluminum heads, right?
The stock lug bolts are steel, right? As such there is even less issue I'd think.

I use Wurth CopperPaste for my wheel bolts as well as its intended purpose of exhaust systems and other high heat areas. Lubri-Moly compound, available at most Porsche online parts suppliers is 1/2 the price for a tube.

I just finished taking all four wheels and spacers off, cleaning the Blue Loctite off the bolts, spacers & inside threads, properly applied Loctite Anti-Seize to all bolts and reassembled. I set the torque to 96ft.lbs., and have a new Precision Instruments split-beam torque wrench on the way. This better take care of the problem. I will advise after a hundred miles or so.
After 100+ miles, the bolts are holding tight, problem appears to be solved.

Do you mean you tightened the lug bolts and they are not staying tight? I'm not sure what that has to do with the spacer. I'm not sure how the spacer is supposed to be secure to the disc without the screw that is present on the OEM spacer kit. Am I missing something?
I installed H&R 7mm front & 15mm rear wheel spacers on my new CAB a few weeks ago, but they just aren't staying tight. I originally tightened them to 96ftlbs., then retightened them a tad after 40 miles. Today after another couple hundred miles I thought I'd check them just to be safe and they were surprisingly loose, by that I mean half a turn. This was not my experience with the OEM Porsche 5mm spacers & bolts. As you can see from the photos they look great on the car, but I am worried nonetheless.
Is this normal??

The wider spacers require new bolts which I originally installed without anti-seize, which is required to achieve the correct tightness at 96 ft.lbs. OCBen stated the specifics in this topic. The small screws that secure the OEM spaces are not required, and not applicable for H&R spacers. Take a look a the whole topic, all the answers are there.
