I have to point out that the worst substance you could have as a heatshield would be aluminium. It is highly reactive for a start, and burns very easily. To coat a multi million dollar spacecraft in aluminium would be foolhardy to say the least!
Logic... Logic... Now where did it go? It's "hull" of heatshield. (which is then covered with protective material)
