Removing 604 horns

[Cal Weldon]

I have the 604-8H and I want to remove the horns as the look kinda cloudy. I am guessing someone used something on them. They are not here where I am so I can't see for myself, but I go there everyday and I can do what you tell me.

How do I remove the horns and what do you suggest to make them not so cloudy and oxidized looking? I wish to remove them so I don't damage the drivers while doing the work.

Thanks.

I had GPA rework a 605A that someone had replaced the multi cell horn with a blue UREI.

I recall they used a solvent and lots of Qtips . I think they used MEK. DONOT BREATHE this stuff .

I'm pretty sure you have to cut the felt ring to get at the screws, I'd shoot for something more along the way of that armor all stuff for blackening things. Not sure what it's called.

Just getting back to this, thanks for the responses. I guess if I am careful, I could just do the Q-tip and Armour-All type stuff.

I wasn't sure if you wanted to remove the whole horn or separate the two parts of the horn. either way they both sound scary. Good luck Cal. I saw something pretty scary on youtube but I wouldn't want to try it. They were using a heat gun on automotive plastic to bring it back to life. also saw a guy on there using Pam....

I've used the heat gun "trick" on my bumpers (86 VW Jetta) to "bring back the black". Not recommended.

Alternatively, I have used black (kiwi brand) leather shoe die with outstanding success on said bumpers and other plastics. Lasts about 5 months before it starts fading due to rain.

It must be kiwi brand though - other brands have a purple hue to them. Found at the local Walmart (only in US not Canada).

I actually have an extra unopened bottle in my desk at work. If you are interested in trying it, shoot me an email with your details and I can send it off to you!

That's a super generous offer. Let me see if I can locate it here and if not I will let you know.

Thanks.

You may want to try a mixture of boiled linseed oil and paint thinner, or straight BLO. It works wonders on plastics and last longer than anything I have ever used. Makes grey whitish plastic turn black and lasts and lasts. Good luck....
