My ballast is about to poop out on me.
I have a replacement coming in but I wonder if I should protect the new ballast with the neverwet spray. I'm just wasn't sure if it would hold up to the heat of the ballast, if any, or if it would be safe to spray it on the eletronic of the ballast. I seen a YouTube vid of someone testing on RC car toy receiver success but don't know how long.
Yes I've have encapsulated/potted ballast. I was just wondering on a alternative way.
What your two cent?

 

If you mean the one behind the dome shaped cover then it should be fine as is, it's got a rubber seal

 

If its your OEM ballast under your headlight it should be fine. If its after market, you may wanna consider a better quality one that is water resistant AMP. OEM ballast shouldn't get wet anyways

 

Unless you have a broken seal or cracked housing (that lets in water) you shouldn't have to spray never wet.
