Ok, I've asked a lot of questions here in the past about getting the trailer
we've made painted. I'm pretty sure I've found the right company and that
they will do a good job.

My question today is: There are parts of the trailer that are boxed in. This
means that paint won't get down in there. But water still will. The water
will drain out. What I'm wondering is: What are good ways to protect this
from rusting from the inside out??

Do paint shops typically have some type of longer nozzels they can use to
get paint in there?

Could they maybe put some type of car undercoating in there?

Is there something I can do?

Obviously it won't be seen, so it doesn't have to look pretty.

Yes...I will as my paint guy, but I'm hoping to get ideas and information
here first.

As always, THANKS to all the people
who take time to answer & discuss!
