HVLP allowed me to spray epoxy prime in the doorway. I was very concerned about overspray, but HVLP overspray is not the same as high presure guns of old.
I waited for a day that had the wind blowing out the door and shot the primer.
the tarps caught the overspray which is more like little drops of paint not like the mist cload you get with high presure guns.
If I would of painted the car with high presure the paint would have been all over the walls as it went out the door.
HVLP stirs up very little dust compared to high presure gun .
200sx down pipes are small.
I bought an extra thick flange for a header made for a 2 inch pipe. the bolt pattern was off a very small amount, and a file took care of that.
