I want to make the engine bay look a little more OEM of years gone by where it wasnt full of plastic. I went for black as it looks cleaner for longer. Also replaced all the silicone with black ones.
With the wrinkle finish paint is a little awkward and took me a good 8 hours to do (on and off of course)... I cleaned the parts meticulously with 'gunk' and then rinsed and dried them. Then used a red metal primer and gave it 3 coats. Once done i baked them in the oven at 90oC for about 30 mins. Once cool i then applied the wrinkle paint which is a pain to use. The nozzle keeps blocking .etc but it turned out OK. The key is to do lots of fine layers.... I tihnk i did about 5 in total.
It then got baked again for about 2 hours at same temp, and this is what makes the wrinkles really tight. You have to let it cool, and then cure at room temp for 5 days before fitting.
Sounds like a pain, but its a good finish if you take the time to do it right. Masking it all off took some time but wanted to get it perfect and have really nice clean lines where i masked it off.
