This might seem a silly question...
The seats on my 81 Silverado are the cloth type with vinyl head-area, back and sides. I have read elsewhere that with some seats (Ex: Leather), putting on a seat-cover improperly can cause wear rather than prevent it.
Is this something I should keep in mind when getting a seat cover? I want to protect against wear, bending, cracking, stretching, weather, spills, etc.. That's the idea.
