So I'm seeing a pattern, in the US cars anyway. 1985 and older cars all appear to have a grey powder coating. 1986 -1987 all seem to have a white powder coating. The grey stands up well to the passing of time, whilst the white finished ones don't. Does the white finished chassis denoted when a TVR started doing the powder coating in-house?.

I thought the "in house" came much later, Chimaera/Griffith era?

Two different types of powder coating...the grey is a non setting and the white is setting, both done externally, neither done to well, the grey if heated melts and drips off the chassis and 'skins' if rust gets under it, the white shows up the poor preparation and thinner coating with failings in high angle corners where the postive/negative charge of the process leaves these places 'dry'.

I have white on my 87 350i...Showing some sign of rust...However Delilah 82 280i had grey plastic coated which looked like new in most places..There was a bit of a joke as to if you had a "Weekend Chassis"...Which meant the chassis was finished on friday, Left the weekend and then coated on the Monday...This allowed the rust to set in pre-coating...

IMHO, sadly, the grey 'non-setting' powder coated chassis can be deceptive, in 'looking good' but then rusting inside the 'shell' of the coating, I have in the past sliced a skeleton of 'grey' off a rotten chassis.

Nowhere ..not quite...Zinc spray oxides under powder coating. IF the powder is left dry and in the tight corners (same issues that they show off in primary schools with metal filings and corners). I have just stripped a full set of wishbones off a customers car that all his bright red powder coating was just a skin over a white oxide powder!!

Thats may be the case, but I watched every second of the coating process and Im completely confident that ALL of the coatings were done to an excellent standard.

And despite this, I will be waxoyl coating the main/usual areas of corrosion, just to be sure.

Quite often the rot is on the inside of the tubes, and the first you know is when the remaining "foil" skin is all that is left, and punctures....

Seems a shame to cover it with a fibreglass body.

Think of the performance with that lardy fibreglass body in the skip!

A long time ago at a kit car meeting I saw an open spaceframe racer, with just a windscreen and a seat inside the frame, the barest instrument cluster, and a V12 Jag engine and mechanicals. Don't know if anyone has a photo or a reference, but I reckon it must have accelerated "quite nicely".....
