No worries, but there will always be some that have experienced problems. Some things to consider, though:

There are manny things that can be done incorrectly when using the POR15 process. For the stuff to flake off that would mean that there would have had to have been a surface underneath that was not preped well enough. Understanding this helps in figuring out if you need ot do something over, longer, etc. If you follow the instructions to the letter without understanding this, the system may fail.

As for muriatic acid, I am not surew why this would work as it is just HCl (hydrochloric acid). Rust is typically FeO2. If you apply acid to the rust you get FeCl2 which is a salt and will re rust when introduced to water in fuel. If you are going to treat the rust use metal ready which has zinc phosphate, or jasco or Ospho with phosphoric acid. This changes the FeO2 to iron phosphate which is very tough.

If your friend did the system as per the instructions, then h shoudl have washed the tank out well with some cleaner that is water based, but disolves all of the lovely stuff that we don't want in our tanks. The system uses "Marine Clean", but jasco and others make a non organic cleaner thaqt will work as long as you rinse the tank really well afterwards. I woudl recommend letting the tank dry so that there is no residual water to dilute the metal ready or other rust converting compound that you may be using. Let it soak for a while to let the stuff work. Then you must rinse very well to remove all of the leftover acid residue. If not, your tank will have a fluffy coating of iron phosphate that will make a poor base for the mechanical adhesion of the sealant.

I am at the point where I acid washed the tank and am going to wash it a few more dozen times to make sure the surface is clean of the acid. Then I will be pouring in the sealant which will mechanically bond to the rough surface that is left behind. If the surface is clean there is no way that the system should fail (in theory).

I wont think less of anyone who decides to do something different (so long as it makes sense) (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)
