Concur with the replies. I 'dabble' in vinyl lettering a bit and yes, these are good alternatives to commercial application fluid. The fluid allows you to 'pre-wet' the surface, reduce or eliminate bubbles, and let you adjust the lettering prior to applying pressure 'squeege or roller'. Work it from the center outwards, taking care to 'work' the bubbles out. If you get one (takes time to learn technique) that is stubborn, just 'pop' with a needle. If you work it to hard, it will stretch and wrinkle, leaving you wanting another six-pack of brew (you did have one for the install, right?)
