Yet More Bondage...
Just been reading a thread in the MK section about foam padding, which points people back to a thread titled Bondage.
To summarise, the thread is all about using an adhesive for attaching the panels rather than a million and one rivets. The general consesus was that
its probably best to use the adhesive on bare metal, i.e. not painted nor powder coated.
Now, for those of us not technically gifted enough to weld our own chassis and have bought a powder coated chassis (Luego, hence not posting in the MK
forum...  ). What does everyone think of applying the adhesive on top of the powder coat. I'm guessing that as long as I'm not relying on
the adhesive in a structural sense it should be ok?? I have no idea whats involved in the powder coating process, am I likely to pull the powder coat
off the chassis?
I also noticed that the polyurethane adhesives say to use a primer, of which there seem to be 3 types... one for plastic, one for metal, one for
glass/ceramics. The metal one says don't use on plastics, the polyurethane isn't going to do something nasty to the powder coat is it?
PTM, it seems you were a bit of a pro in this field in a former life... any tips??
Cheers.

I was thinking about bonding the panels- it does seem easier and may look nicer if you don't like rivets.
The disadvantage is that if you get any damage or need to change anything you can't just drill the rivets and remove the panel- it's going
to be a right mission to get them off.
Cheers,

Too true!
I used a PU sealant when I fitted the rear panel to my chassis. After deciding that the panel was no good I first drilled out the rivets then
attempted to remove the ali sheet.
The sheet was trashed in the process...
... and PU sealant was never intended to be a glue. I would imagine that a proper adhesive bonding tape would be many times worse.

Point taken, but if you have to remove the panel because it is damaged, then surely even more damage to the panel isnt going to matter???
On some panels you may find that after a bit the rivets (on their own) start to work loose. I've rivetted AND bonded my panels to the car, to
prevent the above happening, and hopefully get some more chassis rigidity for free.
P.s. I did however bond to a painted frame, so the bond is compromised slightly. However, the total surface area of the bonded surface is quite high,
so I personally dont see this as being a problem.
Cheers, Stu.
Dont just build it.....make it!

Yup, bonded and rivet too, but to metal, just sanded it off then squeezed the PU sealnt on, easy. I only rivetted every 2 inched rather than every
inch.
