For example, I just did a project that involves temperature sensors to be used in ultrasound, which requires immersing them in an aqueous gel for each use. The TMP37 is a great IC for this work, but the manufacturer instructions suggest that they should be protected from water.</p>

I am not sure why you think this is easy to remove or who have you really consulted on this. We normally use acrylic type for most airborne electronics (Humiseal 1B31 LOC) for its ease of rework and low environmental impact (as well as human impact - the people that have to work with it). We only use Parylene where we have to make absolutely sure moisture needs to be completely sealed off (i.e. air pressure sensors, fuel measurement systems, military avionics). I can attest from experience there is no chemical we can use to remove it (we have to sent the coated electronics to a specialized house to do this); so the only other option to remove it is the Xacto knife (and oh how much fun can that be). Seriously, if you want to look at coating take a closer look at acrylic types as they are friendlier in every way. Parylene is awesome for its purpose; but its purpose is certainly not general electronics (think space shuttle, F15/F16, high reliability / high criticality equipment).</p>

I was unable to fix a board, or even test potential problem components due to this stuff. It gets everywhere and is nearly impossible to remove sufficiently to desolder components without damaging the board or components. This coating has two purposes: 1.) Protect the board from the elements and 2.) protect the board from tinkerers.</p>

Please don't prevent your customers from hacking/fixing your boards. Seriously. This would keep me from buying any Sparkfun board.</p>

I have seen excellent use of CVD machines using Parylene; it is cool stuff. But Codebender is SHUTING DOWN! Please excuse excessive use of caps, but I am panicking.</p>
