Painting The Cold Start Injector
I'm pretty **** when it comes to looks and details about my car.
Although I don't yet have the $2000 for body work and paint quite yet, when I do a job I follow the do it once and do it right principle.
I am going to soon be replacing the cold start injector on my 85 TPI and wanted to paint it with brake caliper paint (The same paint I used to do the lines on the TPI plenum and seems to be holding up well) but have just one concern.
Since this is VHT paint after I'm done painting the object I always bake it in the oven at 200F for one hour to cure it. But this isn't a chunk of aluminum we're talking about here It's a cold start injector.
Yes I am aware that the injector resides in a pretty harsh environment temperature-wise on a running engine but baking it in the oven seems somewhat different. Instead of being hooked up to a toasty engine It will be completely engulfed in a dry, stinging environment while it cooks the paint in the oven.
I can only imagine that this may wreak havoc on the rubber O-Rings and whatever the internals of the injector are made from. When I baked the plenum, I cooked the IAT sensor with it but didn't see any reason for alarm there because it was just a simple temperature sensor. It was designed to do exactly that measure extreme hot or extreme cold. I will say that the high temperature plastic did do a good job of standing up to the heat so that is not a concern.
So are my assumptions correct and should I bite the bullet and hope that the engine heat does a sufficient job of curing the paint, or am I just overreacting and 200F for one hour actually would not do the cold start injector any harm?

VHT TO BE
200° will not hurt it.
Bake one for me, well done.
Happy Racing!
If People Drove Any Slower They’d Be Going BackwardsFog lights are not driving lights. They look dorky. Turn em off slow pokes.
How bout those dorks too scared to drive without headlights on in the daytime!
