bonnet insulation

Postby RyanT24 » Fri Jul 07, 2017 5:35 pm

Hi Guys, does anyone know of a supplier for a bonnet insulation kit for a series 2 XJ12? I think Barretts have them but are there any others? The underside of my bonnet is a bit scabby and would look better covered up, don't want to use the modern foil type unless i have to

Not all Series 2 V12s had bonnet insulation originally. Some had a simple painted finish over a spray of body schutz to eliminate drumming. Hence, it might be easier and no more expensive to have the underside painted to tidy it. Mike.

Thanks Mike, thats obviously what they did to ours then, for the time being then i think i might just remove all the loose stuff since its all in one area and just spray the whole center panel silver, won't be a perfect job but good enough for the rest of the year i think

Hi Ryan,

That pattern of surface rust at the front of the bonnet, ahead of the above radiator seal is very typical. It's not difficult for anyone with painting skills (not me!) to get the underside of the bonnet looking respectable again. On my own car, the chief thing that spoils the bonnet is grease from the aircon compressor. Even new units only seem to last a few years before grease and other debris start to emerge from the bearing at the pulley end and bespatter the bonnet underside. At least it's easier to clean a painted surface than an insulated one. Mike.

Ryan,
My Series 2 had some ,like 1/8 inch thick fibre board glued to the bonnet underside, which of course was original factory fit Over the years it became buckled with the heat and partly un glued. so I pulled it all off which revealed very minor corrosion.

I removed the bonnet, cleaned and primed and painted with matching colour. That was two or three years ago and have agonized ever since about sound proofing. I shall probably never bother to fit a lining as it looks respectable as it is
