Sealing heat shield against pink dust?

[JvdBosch]

The RCZ R's have a documented issue with pink dust settling in the engine bay, with the heat shield as source. As far as I have found out, the heat shield consist of two pieces of metal with a layer of glass-wool insulation inbetween. Apparently the seal between the two pieces of metal is not sufficient and the insulation leaks out over time, spreading the dust.

A new heat shield does not really solve this. I thought about removing the heat shield and somehow improving the seal bewteen the two pieces of metal, for instance with this:
5cm x 5m Heat Reflective Tape Gold 400 °C - Heat Shieldings B.V.
Or maybe some heat-proof sealant like this:
Amazon.com: J-B Weld 37901 ExtremeHeat High Temperature Resistant Metallic Paste - 3 oz : Grocery & Gourmet Food

Anybody has some thoughts on this? Looking for a long term solution to keep my engine bay clean.

Oh, does anyone know the partnumber of the shield?

No idea of the part number, but I’ve wondered what the pink dust was on my R, now I know, thanks mate

It is normal not sure about OCD; I had a brand new heat shield fitted by Peugeot after a local dealer damaged my heatshield (like many seem to be dented) leaning on it. To remove/refit is a complete arse by all accounts front bumper lights etc needs to be removed to get to lower bolts of the heatshield; I was told. The pink dust was evident immediately after a brand new one was fitted. Be more worried when there is no pink dust as the healt shield loses it's efficiency.

There was a used R (possible track car) that had had a Forge 'turbo' blanket fitted to it, would worry me given the huge amount of heat generated by the R.

Just use an airline/blower to remove dust...or have a possible world of pain to replace........
