Following standard practice, most of the external trim was trial fitted as part of the preparation of the bodyshell. This enabled the bumpers and/or bodywork to be fettled to ensure a perfect, even gap to the bodywork. Once completed, the bodyshell was passed on to the paint shop and the chrome parts sent off for re-chroming.

The exception was the rear bumpers which sadly had to be replaced. The car had obviously had a minor rear-end shunt that had resulted in a crease in the middle bumper section and the outer sections distorted beyond repair. Hutsons had trial fitted the new bumper sections, which they’d sourced from SNG Barratt.

One of the reported problems with the reproduction bumpers is that the chrome plating is generally thinner and not of the same quality as the originals. Even so, when the painted bodyshell and rear bumper were delivered, I wasn’t expecting to find the inside faces to be showing signs of rust!

I wasn’t too impressed as this really should have been spotted when they were being trial fitted and rejected. The dilemma now was that these fitted the painted bodyshell perfectly which may not be the case if I got Hutsons to replace them.

The intention had always been to paint the inside surfaces to provide better protection from the elements. So I decided to keep the new, rusty rear bumpers.

Meanwhile the remaining chrome trim had been dropped off to ACF Howell, who had been recommended. At the time, I felt reassured seeing many of the recognised Jaguar specialists listed on their white board of work in progress.

When they were returned, they’d already given the insides of the front bumpers and overriders a light coat of silver paint. However, on closer inspection, the paint was lifting in places on the overriders. Rather worryingly the cause was found to be more rust! So everything would be given a good coating of the silver Epoxy-Mastic 121 that I’d used on the front suspension.

Once all the chrome surfaces had been masked, the rusty areas of the ‘new’ bumper were bead blasted and the insides given three generous coats of epoxy-mastic followed by a couple of coats of Dinitrol 4010 hard wax. Hopefully this should be sufficient overkill to keep corrosion at bay for a while!
