So, I'm a bit impulsive. Last week we purchased an old aluminum trailer. We thought we were thorough before taking it. Now we've pulled the mats completely out and there is a hole and corrosion around some bolts in the floor.
Behind the wheel well, there seems to be some gaping, it looks like it was originally sealed with silicon or something similar. Is this safe? They made it sound like it was a cosmetic issue but now I'm just not sure.
Of course, where we got it from is no help, it was as-is and we're on our own. I'm terrified that we just got duped into purchasing something completely unsafe. Someone talk me down here! Please???

As to the fender- yes, the fender was probably just siliconed to the floor. Over time the fender has been flexes, as has the floor/frame. I wouldn't stress over it. I can't really tell what is going on with the other two pics. Not really remembering bolts through the floor before. But the holes you show don't look excessive. I believe I'd clean thoroughly, and then reevaluate. It is old, but may very well be sound.

Aluminum floor corrosion, preventative measures and corrective treatments have been covered extensively in this forum ... it just happens to be a number of years ago and searching for the old threads can be hit or miss.
You can use google to search for the older threads ... here is an search on Aluminum Floor Corrosion with many threads that you can review:
You will see many threads from the past regarding Aluminum Floor Corrosion from a fellow named "Gard". He was a very active HTW member who guided many of us on Aluminum Floor Corrosion. Look for Gard's posts as they provided very good advise regarding Aluminum Floor Corrosion. From what I can search recently, Gard has not been active on this forum, but his previous posted advice remains timely and current.
I personally repaired the aluminum floors of two used trailers that we purchased following a process involving (in order): pressure washing, sand blasting, acid washing, corrosion treatment, military grade primer and roll on box liner application. For the most part, this followed Gard's suggested treatment protocol ... plus the addition of sand blasting and corrosion treatment. This process stopped the existing corrosion and provided a durable coating that prevented the floor from being in contact with urine. We still wash out our floor after any urine incident, but are confident that future corrosion has be prevented.
Happy reading ... there is a lot of material to cover to understand why corrosion occurs, how to repair it and how to prevent it from reoccurring.
