Touch upâs should be done minimum 4-6 weeks post the initial treatment. This allows time for eyebrows to heal fully before perfecting them for the second time. Free touch-ups are only valid up to 3 months from initial procedure date.
Re: The Tinny sound? Most folks that are concerned about a tinny noise with aluminum boats are referring to the noise generated by the hull moving through the water (which can be modulated/reduced through many different avenues). You mention vibration and rpms, so I'm guessing that you're not referring to that sound.
Another complaint for a sink is that with the stainless steel down in the bottom, it can kind of sound hollow, if you will. So, what the company has done is theyâve coated this so that it dampens the sound. It also insulates it so the hot water stays hotter longer, and it reduces condensation underneath.
