Sealer....

Alright, I primered of about a 2' by 2' section on my bed...and I'm gonna scuff up the exsisting paint and the primer and go for it...do I need to seal just the section, or do i need to seal the whole truck?

Just the section if your keeping the same color paint and your not talking about primering your whole truck Good luck!

my truck is beige now, (with mustard yellow primer in that spot)....and I'm painting it all flat black with blitz black...So I'm not keeping the same color that's on it right now...Can I still get away with just sealing that section? This bed is really beat up, I'm not expecting it to look perfect, but I'd rather it look like the other guy's fault for messing up the bed rather than my fault for doing a crappy job spraying.

Eh, eh? I'm just a scared little boy with a truck that's SCREAMING "paint me"

Do I need to seal the whole thing or just the bed or just that section?
