Rear hardtop securing plates

Postby Nick3 » Thu Mar 12, 2015 4:25 pm

Greetings, Fellow Enthusiasts.
Long story short - I had to remove the chrome rear hardtop securing plates, the ones that the Frankenstein Bolts screw into, and now want to re-attach them.
I don't trust the water-sealing ability of the original, and very compressed, rubber gaskets, but will be replacing them anyway.
I was wondering what might be a suitable gasket-goo / sealer, to ensure a watertight seal, but which won't bond them permanently to the car ?
Thanks in advance.

Don't use gasket sealer.

Just replace the rubber gaskets. Either items from Mazda, or but a sheet of rubber from CLark rubber (or similar) and cut it to size. (make sure to clean any dirt etc that has collected)


The silicone works by sticking to the items to seal them, if it's not stuck water can weep through where it isnt stuck on.
Rubber will be compressed tightly enough to prevent water wicking through.

IF you want to use silicone still, and aren't concerned with it being sticky, I can recommend Sikaflex (forget the exact version, but it's the black one)
It's the stuff they use to seal windscreens..... BUT it's very sticky, you could just about glue the car to the ceiling with it.
