Over 40 years ago I was researching matching paint for my 70 TR6 after an a=
ccident (I still have it). The car was painted white after someone had spr=
ayed it with candy apple metallic red. Stripping down paint on body panels=
, the original lacquer paint were red, dark green and yellow. I had seen o=
ther white TR6's but my research at the paint supplier showed that white wa=
s not an original TR6 color. The color I went with was Jaguar white.
The shop that painted the car had problems with the paint at the seams betw=
een the panels cracked--they had tried some fillers to fill in gaps. Turns=
out the panels pretty much just hang on the frame and flex independently b=
ecause they are held on by "square threaded" bolts, which do not pull sheet=
metal panels together like modern sheet metal screws or fasteners. Back t=
hen I was not able to locate these square threaded bolts from any source, i=
ncluding a local hardware store that had been around since the early 1900's=
.
The other thing I found out by bringing in a panel to that hardware store t=
o get fasteners was that WW II veterans recognized that this came from a Br=
itish car because the British would dip their metal parts for everything in=
vats of lacquer paint and air dry them since their weather would immediate=
ly rust everything. That's why original TR panels, including every nook an=
d cranny have the same color paint. And if you scrape the color coat--no p=
rimer.
I went to a lot of "pick and pull" auto wreckers in the 70's trying to find=
body panels and these square threaded bolts were on all of them. When I t=
ried to connect panels with these original bolts, the bolts would not cinch=
the panels together tightly and would quickly fracture if I tried to torqu=
e them down. If you find a panel where the bolt holes are deformed or you =
don't find paint inside the hole, it probably was put on after a replacemen=
t.
So a black engine compartment was probably sprayed over the original panels=
because the car is pieced together from panels that didn't have the same o=
riginal color, or maybe it was sprayed with a high temp paint.
The biggest problem with lacquer dipped panels is eventually there will be =
lacquer check. Spraying stuff on top can hide it for awhile, but eventuall=
y the checking goes through the new sealants and top coats (maybe there are=
new sealants that can prevent this that have been developed over the last =
40 years, but I doubt it since all of the "solids" that used to be availabl=
e as fillers in paint are gone, and those old ones would not stop the lacqu=
er checking, just hide it for awhile.
Anyone remember the debate in the 60's on Ford with its enamel paint and or=
ange peel problems, versus G.M. with its smooth lacquer finish which probab=
ly wouldn't start checking while you still owned the car.
All my info came way before the internet and I didn't look for my old notes=
when I was trying to keep my 70 TR6 original. My research showed mine was=
pieced together and very little was original from the same car, and I neve=
r did find a TR6 in the boneyard that had all color matching panels when yo=
u pull panels apart and and look at the color of the seams.
Anyone else come across these square threaded bolts?

<original post> Hey Jeff. Well, a "paint job" is a very relative conversat=
ion. If the
engine bay is black then it's been repainted - someone correct me if I'm
wrong but Triumph painted the engine bay body color.
