Hey guys, its been a while since i have posted, busy with school. Now that I am home on break I am planning on doing my first real detail,since school started in August, that being said I was wondering if i could pick your brains, and get a recommendation on a long lasting, really tough sealant that sheets very well and will look great on my black sapphire z4.andi s also onr friendly, because at school i dont have access to a hose. Thanks in advance guys i'm sure you will know exactly what i need.
