No matter how carefully you apply a screen protector to your iPod, air bubbles seem to make their way between the plastic cover and the screen. The best way to remove air bubbles is to work them toward the edge of the screen protector. Once the air bubbles reach the edge, they disappear.o matter how carefully you apply a screen protector to your iPod, air bubbles seem to make their way between the plastic cover and the screen.

The technical difference is that oil-based paint has a non-water-soluble base to it, and water-based (latex) paints have a water-soluble base to them.(Latex cleans with water, Oil does not.). The practical differences are pretty severe. Beside the chemisty involved, probably the most important difference to you is that oil based paints require a solvent such as mineral spirits (paint thinner) for clean â¦ up while acrylic paints only require water.
The powder pigments are the same in both cases, but the medium used  to bind the pigments are entirely different. Watercolour paints are  finely ground, water soluble, gum b â¦ ound, and transparent. Acrylic  paints are ground the same as oil paints, insoluble once dried,  acrylic plastic bound, and opaque.
