as said above, home products take longer and need more to seal u. I just painted my friend grey for her marceline cosplay. we bought the smallest size of final seal (by ben nye, it works for any brand) and barely used a fourth of it. we painted her face, arms, fingers, and chest! its about the same price as hair spray too.
