Doing it middle of this week and decided to document the steps. Will add to this as I get them back.

They came off easy, took just a few minutes using a 10mm socket.

All cleaned up and going to the coater tomorrw.

Flat black is the plan!

Had mine done a gunmetal ceramic coating. Did powder coat at first and learned my lesson. These tips get way too hot on the 991, and something that withstands higher temps like ceramic is the only way to go. The powder coating failed on my tips. Started cracking and chipping off.

You will love it.

STG, I'm pretty sure the coating failed on your tips because it was undercured. That's the symptoms of that. When powdercoat gets overheated, it gets soft, it doesn't chip.

To be more descriptive it looks like it bubbled up and the raised parts popped if that makes sense. The temp threshold isn't enough for powder coat. The tips are a foot from the mufflers and not that far from the engine either.

improper prep or undercure. The tips have an air gap around them. I've got 11 years of professional powdercoating under my belt. But, since I just did my tips today, we will see how they hold up.

MJG911, what constitutes proper curing? Thank you. Assuming proper prep.

STG

Keep us posted, I've researched this quite a bit and have talked to many guys. Many who told me I should never have powder coated. The 991 tips get HOT. The ceramic is good to something like 1700 degrees or more. Powder coat is like half that at most.

Rear engine car and close mufflers = hotter than your average car.

not to threadjack, but this is what happens when powdercoat gets too hot. You can see it melted and actually slung some off of the wheel and onto the brake rotor. plus not seen, are other runs in the coating from heat.

I will be interested in your results. I am in PA, but can see NJ, across the Delaware River, from my house. I may well follow your example if you are satisfied and will share the details of where you had the coating done.

STG

So what's the maximum temperature threshold for your powder coat?

Isn't powder coat two words??

MJG911

I guess it is, I've seen it both ways. about 300 continuous and up to 400 short duration. I think that wheel got to over 600, but that was on my race car and my thermometer was only rated to be accurate to 450.

also, they do make powder good up to 1200

STG

The 991 tips are hitting well over 800 degrees if not much higher. You need ceramic. You'll see.

Now ... back to spiderv6's scheduled programming

Love my ceramic coating!!

My tips came out well - I'm very happy with them - I felt the chrome was out of character for the car (IMHO and with colour scheme I selected)
