What is the best low-maintenance approach to coating power-tool-cleaned field weld joints on process pipework that is protected with thermal-sprayed aluminum?

From David Shaw of Barrier Ltd on October 15, 2013:
There is a proven technique and process for such situations, TSAP - Thermally Sprayed Aluminium Powder. The surface prep is mechanical, by abrasive disc and power tools (not grinders) to a bright metallic sheen. There is a pre-heat requirement of the field weld to 90 degrees C. The powder is applied by specialised portable oxy/acetylene spray gun, which is not suitable for all applications due to the open flame of the spray gun. Application is by professional and qualified contractor only. This approach achieves proven adhesion test results. Beats an ST2 and 4 brush coats of aluminum every time!   

From firos habeeb of PP on September 13, 2013:
Performance of a coating is directly proportional to the degree of surface preparation.  No coating can perform if the surface preparation is inadequate.  Hand tool surface preparation is the lowest degree of cleaning.  If no other option is available, hand tool preparation followed by surface-tolerant epoxies will be an option.
