The last two days I was busy with lacquering the underbody. The fact, that my big last paint job (the monocoque) dates back somewhere in June 2012, was responsable, that the underbody didn’t got perfect because I was a bit too less patient. A few times, the lacquer runed away a bit and made a bit an irregular surface. But not much.
If someone detects a difference between this and the real underbody (except the size) the person should tell me. 😉
Regarding the heat shieldings I have almost no reference. In my opinion, also the area under the radiators should be heat protected. But at my pics of the engine cover, there is no heat shielding at the radiators area.
Underside of the underbody.
With the heat shields I covered the area under the engine and the lower line to the water radiator.
