How to fix roof rib? - Defender

[VladTepes]

OK... so every time I do something on this truck another little 'surprise' raises its head :bat:

When I removed the roof lining I found this.....

That is the centre longitudinal rib running from the middle cross rib to the front windscreen. (make sense).

Anyway its obviously supposed to be a little bit more... attached.


Would I just scrape out some of the old glue, and glue it back it with some sikaflex? (If so where would I get sikaflex from?)

Please help.

Is it not supposed to be screwed / welded to anything at the front? Just sikflexed to the roof panel?

Vlad, as 87county has said bunnings will have what you need, but there are many different types of Sikkafex. Look for one that is automotive grade and is an adhesive (for metal) rather than say a sealant.
Also, get into that gap with some sandpaper wrapped around a flat stick and get the paint off first. Bare metal will be best to get a good bond.

We can get It from Bunnings , and Masters down here , if you don't have those , most auto suppliers should have It ...

[uninformed]

Since it is most probably aluminium you will be bonding to, if the paint is clean and has been bonded well from factory, it would be ok to sika to that. If you clean the paint off you will have to etch/prime the aluminium. Plumbers pvc cleaner/solvent works well.

There is a difference between simply sticking to the surface and bonding to it.

Sika make primers, but bunnings most probably wont have them on the shelf.

I think what Vlad might have been getting at, is should this not be more seriously attached? If it's just stuck with glue, what's the point of the rib? :confused:

[VladTepes]

Indeed that is my latest question?

Anyone have an answer?

To reduce reverberation I would have thought.

They glue planes together. .. seriously

And PT boats in the good old days, Mosquito A/C all LR vintage :)

Sikaflex 227 i would be thinking

Multi-purpose polyurethane
Suitable for automotive bonding,sealing and seam welding
Can be used for vibration reduction and sound deadening measures
Fast curing, can be painted and sanded as soon as skinned

A supporting rib over a long span adds more strength than nothing, but less than being riveted along its length.
Granted it could be fastened better, but then again, its not designed to walk on, just take the load of a wayward magpie or the occasional heavy splash of rain :p

probably more likely there for wind pressure at why speeds.
