Kframe, engine bay, front suspension questions

I have done this. I recommend buying an inexpensive low pressure gun (about $160). This was my first time spaying, rather intimidating (I am a mechanic not a body man). These are low pressure - so very little over spray. Now you can spray from bulk pre-mixed single stage paint. Now that I have the gun, I can shoot paint or primer in any custom color. I say- go for it!
