Re-painting satellite dome

My satellite dome was painted to match the coach from the factory... but the paint is coming off and I need to re-paint it. Is there anything special I need to know? I just plan on sanding the old paint and re-painting with a spray can. What say you?

Hmm.. Would it be worth it to take it to a body shop and have them primer and paint?

Read an article several years ago about just such an undertaking. Something to do with a fellow painting a dome and could not get a signal afterward. Turns out he had used some sort of paint with a material that would not pass a satellite signal. I believe he was using some sort of reflective paint. Too many years to recall clearly :(

Check with one of the manufacturers like Winegard, as I am sure there is a special paint for the domes. I doubt if you will be happy with regular automotive paint or hardware store paint as you will likely block the signal.

We winter in Yuma. Mine started looking crappy from the road so I took it off, stripped it, then took it across to Los Algodones and had a desert mural painted all the way around it in colors that blended with the RV. I like to haggle so I got 'em down to $40.00 and looks way cool. Signal is fine. Had them do my portable dish also (another $20.00). That being said, if you take it to a body shop, it's gonna cost you some serious jack between matching the paint and the clear coat. If that was my only option as it may be yours, I'd see what the price on a new black one was since it's going to happen again. Paint gets beat up from the road and weather. You can also check e-bay for a black one.

Do not use any paint that has metal in it, such as iron oxide, titanium dioxide, zinc chromate and others.

Strip all the old paint off. If the antenna is metal, just clean the rust and do not repaint.

Use a very thin coating of paint, otherwise the distributed capacitance of the paint can change the resonance and cause a downward shift in frequency reception. This could prevent the antenna from receiving frequency of the intended signal.

In the "old days," paint was made with a lead based material. Shy away from any lead (or iron) based paints as they will cause loss of reception.

Personally, I would call the manufacturer of the antenna and ask their advice. They may even have a special paint that can be purchased.

(Research is great! - sources - Internet)

Happy trails.

I took my exterior refer door off, (has all three colors of paint) to a automotive paint supply and asked them to color match. The tan color on the door is what my A/C covers are painted with. As WayneM stated, you need to use a non-metallic paint. If you intend to sand to the original plastic, there is a product called "Bulldog". It's a plastic primer that will make the color paint you select adhere better. "Bulldog" can be purchased at Home Depot.

Thanks for all the info... I just went with Krylon Fusion Plastic paint. No priming needed. Also, no interference with signal. Simple solution to simple problem.
