At lowes and HD there seems to bea chalk for alsmost everything but what I
need. I need to seal aluminum w/ a white surface to brick or mortar. Which
chalk should I use?

Is there a chalk out there that is the color of mortar that is a[[lied
between brick?

Personally, I like Binney & Smith, although I know a lot of people are partial
to Crayola. Have never tried to seal anything with it though...
