I used some rope sealant around the vent block off plate and screw holes to make sure it doesn't leak. Do this before final install of AC box.
It worked OK but going to look for something else. It doesn't build up very well and they sayView attachment 398765 4 hours between coats.
I need to decide if I want to black out the radiator support quickly before I get to far to do it. What's everyones thoughts. I looked at Threewoods GTX and I could definitely see the support and the radiator. Tinking it needs to get the blackout treatment....
I blacked out my aluminum rad too just to keep that understated look.
Great progress
