Did you use any kind of etching or prep formula on the galvanized steel? I was kinda freaked out to paint my trailer cuz I've heard mixed results and the only sure fire method was some sherwin Williams industrial grade chemical etch and elbow grease.
seemed like more than I felt like tackling... at least this year.
actually they said not to use self etching paint because it could cause corrosion under the paint, used zep degreaser/then muratic acid rinsed well then right before i got ready for each piece did a vinegar wipe let that dry like 20 minutes is all it took and i couldn't get moisture with a paper towel then i sprayed. also huge diff between galv thats less then a year old and anything older then a year or two they say is toast and wont shed anymore but i wasn't taking chances
