Bob,
Clear coats are actually porous and can absorb whatever is left on the surface. I just saw one of my other forums where someone said a family member spilled Coke on the hood and didn't wipe it until the next day. You can imagine what Coke will do to clear if left on the surface.
Hi Mike...
Thanks. Yes, CC's are porous. Some more than others after being in service for awhile.
(I only brought this up because some folks say otherwise.)
-That's also why I was advocating using a paint decon system to "flush out" as much
contaminates/dirt as possible...before even starting up a polisher!
Less dirt-on-the-pad that way...IMO.
-Depending on it's environment, I don't believe in deconning a vehicle all the time...
When new, if never been polished, every couple of years or so...shouldn't be too hard to schedule.
-Even when using clay to remove bonded contaminates, some contaminates are 'sheared-off'...
Where's the rest of those sheared-off contaminates? In the CC, I'll say...
Waiting to be removed, along with some CC, by abrasive cleaning/polishing...
winding up on a pad...making it 'dirty'...perhaps a chance of introducing
unwanted blemishes to the CC.
-Now...those sheared-off contaminates are yet another pathway(hole) for heat/moisture
[and sometimes CocaCola

] to enter the CC and begin their ravaging escapades.
-To me...Claying is a often misunderstood/misused/overused
abrasive-'detailing-tool'/process.
-But...Once cleaned/polished:
Gotta keep a sacrificial-barrier on CC's to increase their longevity, beauty, etc.
