Another alternative, have used them twice, the UPS Store made the corrugate shipping boxes and stuffed with packing material. From Swain's web site:
" Like all of Swain Tech’s coatings, White Lightning™ is a performance improving coating. What makes White Lightning™ the best performance exhaust coating
1) White Lightning™ really is ceramic so the material is a superior insulating material.
2) White Lightning is applied much thicker than any of the cosmetic coatings. White Lightning™ is applied about .015” thick compared to about .002” thick for the cosmetic coatings................."

The material is white only, I then sprayed black with high temp paint. The surface is ceramic, feels like rough sandpaper.
