Bike looks like it's in great condition and I love the color! It reminds me of my first car. 1969 mustang couple with an in line 6 cylinder. They called that color Aztec Blue
Congrats and good luck
Back when Gulf Oil was big racing sponsor, that particular combination of light blue and orange was their team colors. Look at racing cars or pictures from the '60's, and you'll see it. So he should probably leave at least one of the "Gulf" stickers on to go with the paint job, but I agree with him that pulling off the rest of the stickers would improve the bike.
