I just wipe the area down with 70-90% rubbing alcohol. Most new hulls have some type of wax residue that helped release the hull from the mold, which won't allow the decal adhesive to adhere.
If it's a lower quality decal, I will first apply it to a piece of vinyl (decal), usually black, trim to fit, then apply to hull.
Example- this IAFF (red decal) is cheap, so I used the black vinyl and trimmed to fit.
