so I have joined this forum to hopefully get more help than another forum I was on. I have a 2011 ram 1500 that I keep flawless.
so I thought
after washing yesterday, I noticed a small cluster of bubbles below the antenna on the front pass fender.

after doing research, I see that there is a pad mounted to the fender in that location, I see no visual rust around pad.

I did spray some fluid film around pad as it seems to not be dripping in and pad seem bonded well.

what are my option just leave, or should I remove wheel well and try to pry pad off to access how bad it could be.

how difficult is it to replace fender, is it bolt on after painting or welded and glued.

I am going crazy to think my truck is rusting after I tried so hard to keep perfect, probably wash and wax more than I drive.

please offer suggestions.
