The proper stuff to use is called DumDum. It is a black non-setting sealant a bit like thick putty. It is also used to seal in the windows. Youn can get it from Paddocks.

Personally I don't like DumDum and I detest silicone or similar on joint that you may reasonably be required to take off in the future, such as gearbox/transmission tunnel, floor plates, etc, if for nothing other than access.

I have used a foam rubber sealing strip which is self-adhesive on one side. Press all around one panel and then bolt  up. The foam rubber is compressed between the joints forming a weather tight seal. But the beauty of it is, if you need to take that component off, it will come of and the foam strip can be scraped off easily, so less mess and hassle. It has an added benifit of better sound insulation I have found. This type of sealing is frequently used in ductwork and ariconditioning units, etc.

I think Screwfix have started stocking it too now. I kinda get mine for free at work..... :wink:

If you're after non-setting waterproof putty, I've come across Plumbers Mait before now from B&Q, or any hardware store. It's a non-setting putty that plumbers use, worth a try perhap? Comes in 1.5kg or 750g, and not expensive either.

Plumbers mait would not be of use in the applications described I am afraid. It is primarily a jointing seal for threaded pipework. Used between floor plates for example, it wouldn't cope with the minute movements and would end up messy.  :wink:
