Wow, I’ve never heard of this before …. And it makes sense.

So this leads me to two more questions:  

<![if !supportLists]>1)                  <![endif]>Given the Engine Mount is a highly stressed piece; is it acceptable to weld a tab so that something can be bolted to it ??  

<![if !supportLists]>2)                  <![endif]>How about Electroless Nickel Plating ???

Here are two things that might work to protect the  tubes:

  

 1. First wrap the engine mount or structural tube with  Aluminium heat duct tape two layers thick then install the cable  ties.

  

 2. Use self vulcanizing silicon tape two layers thick then  apply the cable ties.

  

 I think the tapes would keep moisture away well  enough.

  

 The silicon tape might help reduce wear due to  vibration.

I like this solution because the silicone tape is pretty much heat-proof,

and the self-vulcanizing aspect means it's not going to slowly unwrap on

you like black electrical tape would.



That being said, it looks like most of the planes near me have used black

electrical tape.



Either way, check it when you have the cowlings off, and you'll be fine. 

You're not going to get enough motion under either kind of tape to wear

through the powdercoating on the mount.  And you certainly don't need

expensive and heavy Adel clamps.

One easy trick is to buy a bunch of different  diameter plastic tubing and cut small sections to wrap around your engine mount  before using your tie wrap.

I used a length of automotive heater hose split lengthwise.  It actually has threads in it like a tire and there is no way a tie wrap will cut through that in my lifetime.  I think it would be a long time before it cut through the plastic tubing as well.
