Plating old exhaust tips is really tricky
I had a very lengthy time getting chrome on these tips. The plater seemed to be so busy that my lot would sit for months and my calls, emails and texts were not frequent but never answered. The estimate of completiion was 6 weeks from Sept, which came and went with no chrome.
I finally just showed up at the platers and talked with the Boss, the owner's son. Aparrently the carbon exhaust buildup in the tips will kill their Nickel tank and we agreed that i should hot tank these which I did 3 times for over 4 hours in heated solvent cleaner.
Returning back, the owner's son inspected and accepted them. A few months later, no calls or status so I went down to the plating shop again. Apparently the Plater who was actually doing the work disagreed with the owner's son and still thought there was carbon because he heard rattling inside the resonator tip compartment.
They returned the tips to me and I drilled out much of the rear to give access so I could sandblast the inner resonator cavity.
Returning to the plater, they sat on his desk for months with no calls returned.
Again, I just show up and the platers are stumped as they still think this will contaminate their Nickel tank and don't want to do tyhe plating. I'm starting to see a trend here.
Finally I suggest through bolts and sealing both ends. I ask the Plating shop owner's son and he agrees. I suggest washers and a sealant, perhaps RTV and he confirms that is OK. I seal them up and return them, only to wait more months to hear nothing....
