Why Polyurethane Sealant ?
Getting exciting now ...at stage of sealing cracks carpeting (well rubber matting) and trimming etc
Question though..
Is there a reason for using polyurethane sealant in motors as opposed to silicon or anything else ?
Polyurethane sealer is relatively expensive compared to other stuff and I see in the Screwfix Catalogue that they have "weathermate"
Flexible Roofing Sealer "sticks to timber, metal galvanised steel" and its £3.49 a tube. Cheapest I've seen poly is £5.00.
Would this stuff or any other cheaper sealer be ok ?

A lot is down to the characteristics of the products too - shear strength, UV degradation, resistance to chemicals.
Silicone is an inferior adhesive in a lot of areas.
Unfortunately this is reflected in the prices - I've used Sika products for years and never been disappointed.

shop around though as prices vary from retailer to retailer!

Theres a place down here that doeas Polyurathane Black sealer for £2.65/tube.Trago Mills. Also does other cheap bits and bobs.
Its the muts and I used 2 tubes. Bastard to get off the hands though. And your best clothes when you really know that you should have been doing the

Bl**dy 'ell!
is that all?
What nozzle you use... hypodermic needle size?
We've used 5 IIRC! 
But then we've PU'd everything up... to stop it rattling. Obviously we would be able to hear a pin drop @ 90 ...
But then again...

another alternative is the sealant used for sealing up guttering etc an exterior weatherproof stuff from homebase or b&q has the added bonus of
being black
