Cavity waxing box sections

Anyone done theirs? i want to to my sills and lower inner rear arch sections but want to find out more about drain hole/plug locations as i dont want to block any up, For the sills on the toyota diagram it shows plugs on the bottom of the sills, anyone able to shed any light?

Will do the very same in the next months right after my car is back from the paint shop. I'm going to flood every cavity, even on the inside though. Just try not to overdo it and you should be good. And I'd rather something grease based like Mike Sanders rather than wax, which keeps on creeping when it gets warm again.

Ive ordered Builthamber dynax S50, seems to have good reviews online, and Bilthambers products have all worked well so far for me with rust converting, removal etc

There is a hole not plugged just inside the sill fold in front of the rear wheels which I 'think' is a true cavity.

Quite a few rubber bungs elsewhere some go straight into the cabin or boot so it needs investigating, it would be good to get a definitive answer on all holes bunged or not
