And then there’s galvanized trailers , which seem to hold up really well , but just get dingy after a while ... Boat trailers (here anyway ) are usually galvanized .. The FS trailer is ...the only rust was on the non galvanized steel parts ...
JMHO , boat trailers make better trailers for Foamies , and anybody who lives near the shore (any shore) can usually find an old boat trailer pretty easy and cheap (especially after a major storm ) ... usually better built to stand water exposure , able to carry more weight .... considering a single large outboard motor alone can weigh as much as my whole FS...
Chasing rust is never any fun ,
and you Must do a thorough job , or it will only re appear later ...

Having hung around my brothers auto body shop many years ago , we learned that rusted panels were better replaced than repaired ... repaired panels eventually rusted through again , no matter how thorough we were... Rust never sleeps ...

On trailers , you just have to do your best and just keep chasing it ...

The “nature of the beast” ...
What a difference a couple days off makes ... feeling better now , aches and pains starting to disappear ... even my attitude has improved ...

Rest is Good !!!

And it’s given me time to just stand back and make some observations ... Such as noticing that all the parts of the FS are starting to FIT better

... The extended glue and paint drying (curing) and continuous heating and cooling (expansion and contraction) has caused the skin to become more uniform /tighter, small bubbles (slack areas) have disappeared, the fit much better/tighter now ... Looks like everything "shrunk to fit" ... much like F#1 , which is very tight now after all these years out in the weather

.. and given the observation on #1 how after a hail storm , the foam ands skin eventually healed itself , this confirms the auto- fit theory .. Just sayin' ...
