Another good thing about it is by doing it my way you have a simple method of checking that you have a good over all even run of shielding, by lightly sanding after the mixture has gone off gives you the same as a carbon track on a pot or preset so by applying conductors both ends ie copper tape with enough copper exposed for testing each end then off you go around the coil.
Two coats takes you into reliable kohms per sq inch.
Providing you do the fine sanding after its gone off after say 2-3 days you can bring the resistance down applying more coats.
Todate as stated previously the kohms per inch is magic on the TGSL which is two coats and a light sanding.
Let me put it this way, If I can reduce falsing to almost nil without loosing depth, you would have to agree the shielding is doing its job.
I have proved with no shadow of doubt that thats where the problem lies with those who have used mylar blanket, because its patchy far as continuity, hence why the quick fix is running copper wire around the lenth of the coil to make up for the o/c with every crease within it, some that cannot be seen by the naked eye but can be detected before copper wire applied with a simple ohms meter.
The kitchen foil which most of us have used for years, if applied correctly is constant, ie little falsing but the draw back been its to good as it also screens out things we need to detect.
So doing extensive tests in practical terms in real situations is why ive come to this conclusion.
The reason why ive not posted yet is because for instance the formular Ive used has now been on test for nearly three months, no cracking or change in resistance either on the coils or styreen housing infact it like granet, would have to be hammered off with a chisel, and is above my expectations
However when first applying for the first 48 hrs its up and down like a yo yo, so was hoping to give it say 6months then tell all rather than jump the gun.
Like all projects experiments on here it will always be ongoing but feel theres a big leap been made here far as DIY shielding of coils and housings.
Warm regards
