I was planning to plug it with polyurethane sealer, if I get access to remove it when the wing is fitted to re-Waxoyl the sill again in a year or two, we’ll see later.
I was just watching your brake calliper video, that Waxoyl is pretty thick so I think it will push most liquids through it, I think the nozzle is a bit blocked I’ll look at it, I have still the crossmember to do and then on to the brakes.
@Stevie Cuz cool let me know if you can it may be something I will get a hold of and throw some transmission fluid in it. For the caliper video if you rebuild them the seals have different sides, so watch how the old ones come out. Not sure if I mentioned it in that video.
