1:12 Tamiya Porsche 910 :- 5- Exhausts

Now to do the exhausts.  The pipes were done as per stage 7, but to make sure the pipes C16 to C21 set in the right position I dry fitted them in the mounting holes on the engine block till set.  All what was then needed was to sand & fill the complete system to remove any seams.

When it came to painting I followed Tamiya's instruction & sprayed them Black...  WRONG! just see below how they came out

Having seen race cars this is not how it should be.  Time to give them a sand to take off most the paint without removing any detail & re-do them. 

This time I gave them a base coat of Vallejo grey primer & allowed it to cure.  The front part of the pipes in a 1:1 mix of Vallejo Gun Metal Grey & Matt Black & the box section in just Gun Metal Grey.  The rear pipes were done in Vallejo Buff (976) as if coated in a heat protective layer & allowed this to dry for 48hrs.  All that was needed then was to scratch back some of this layer to show the grey base to simulate wear & tear.  To me these now look more real than before.

With the pipes set at the correct angle they glued into the engine block with no issues & there you have the complete unit ready to mount in the chassis.
