Plastic Coating
I like the look! I have an '04 Titanium Limited with color matched running boards and roof rack. I really appreciate the lighted running boards. I like the look but am not happy with the OEM coating performance.
Even mild duty off-roading easily scrapes the paint off my running boards, right down to the black plastic. Perhaps Toyota made a smart move in going to black boards and racks for the '05 models. Maybe not as sharp in appearance, but more practical.
Keep us informed on how your coating job holds-out, particlularly in regards to adhesion.
As a coatings professional (and supplier to Toyota in the US). I am a little surprised on Japan's plastic coating adhesion results. Not sure excactly what they are using or the process. It may or may not even be our (corporate - supplied) coating.
I also wish Toyota used color-matched primers (as does Honda for most of their models). I like silver, for a variety of technical reasons - particularly because it doesn't show the dirt as much as other colors, but scratches and scrapes do show over the gray primer. If I had it do over again I might opt for my second favorite color - Galactic Gray. A more forgiving color over the gray primer.
Great job!
