header wrap? pro's / con's

I wrap them really tightly after soaking it in water hanging on a hook in my garage. Then I used near an entire can of silicone header wrap black spray paint. (i.e. I did it right)...
again it's been almost two years and the next time I have them out I will repaint them... I would have liked to have painted them again last year, but I don't want to try and do it with them in the car as I don't think I'll get a nice even coverage and I don't want to get that crap on everything else...

I bought a used set of TTI 2'' from a guy in Witchitaw about 10 yrs ago , he had them wrapped , ''over chrome'' . I rewrapped them after straightening 1-3 tubes where he had them mashed up for steering box clearance. After I had them about 5 yrs, I got tires of the fiberglass and took it off and had them hi heat coated black.
The chrome was scaling , and all most decayed off, blasted them pryor to coating , so far so good now.
