Is there a reason not to conformal coat a receiver? I have searched the forums and most of the discussions are about epoxying the receiver. Does conformal caoting cause a weaker signal or...... Let me hear your thoughts.

I use conformal coating on my receivers with no problems
there are plenty of reason NOT to conformal coat your receivers...

Ok Jan , what might they be?
I know that alot of the guys running the larger gas trucks like to run them through water. To protect thier recievers they simply take the cover off and inject a crap load of silicone into it ensuring that the circuit board is completely covered, then then they just put the plastic cover back on the reciever. I cant really see any downside to doing this.

Unfortunately, the acetic acid given off by many silicone glues is highly corrosive. This can wreak havoc with bare copper circuit boards and component leads and is not recommended.
Traditional conformal coatings can void a manufacturer's warranty. I use CorrosionX and water-soaked receivers are not a problem. But then I haven't sent one back for repair either.

I have used 30 minute epoxy as well as hot glue.

I also use Corrosion X. Some say it is old technology, but it has worked for me.

as a conformal coating expert that I was (here), I must say that if you use the appropriate material that does not attack any components (some do not resist to the thinner) there are only few reasons why not coating receivers, like material going in areas by capilarity, for our application in FE boat, we may want to use polyurethane material, that's what I'm doing with Humiseal 1A33, it is the best compared to other type, I had a customer few years ago who did a test on submerged pcb's, only the one coated with polyurethane was still functionnal under water!!! Also in the automotive industry, only PU are used for their excellent properties! It seems some new generation of materials like Parylene or water based are even better.
I like Doby's idea of using 30 minute epoxy
