Other than making things slick,whats wrong with Armor-All? Just Askin.....

Well:

• attracts dust
  
• turns your tires brown
  
• messy
  
• stinks
  
• contains a petroleum base that strips instead of protects
  

I could go on but you get the picture. I really don't like the stuff but your mileage may vary.

also when u amorall the bedliner and use rubermade tubs. the big ones to hold things..and those are armoralled also..its like a skating rink lol
