I located three small bubbles on my hood (none next to ea other, but all abv a brace) , a few months back...but cannot figure out if its paint bubbles from last paint job that I didnt see before OR if I didnt get it clean enough before it was painted 3 yrs ago ( I bought a used hood with some rust..)...if thats the case I think its probably not worth doing again (as its probably is coming from underneath and the braces are in the way), maybe I will just buy a new Goodmark hood and paint it...
