I used mechanic gloves everytime I work on heavy stuff like removing lug nuts or using power tools and they are good in protecting your hands, but re-installing parts that needs a good dixterity (spelling?) I use baseball gloves. They are not really thick leather and has elastic backing that really make tight fit in your hand. I buy them by the dozen after the baseball season.
I usually use the cheap P5 per pair na gloves made of cotton thread (parang ginanstillo)....tapos merun din version ito na plastic or rubber coated yung palm side (mas mahal ng kaunti). Available ito sa ACE, True Value and even sa suking paint/hardware store.
Yung kakilala ko na mechanic will usually cut about an inch sa tip ng thumb and index fingers para mas madali sa grip and feel ng tornillo or others.
Hindi lang siya maganda kung ma-eexpose sa liquid like gaas or fuel yung ganitong gloves kasi it get soaked. Anyway madali magpalit dahil mura lang.
Yung matyaga kang mag-laba pede ring re-usuable ito until the garter worns out.
