Having left my recently acquired Fiero outside in the elements and, with an improperly sealed windshield and subpar cover tarp, water intruded inside and sat for several months. The not so surprising results are rusty floor pans that need to be dealt with. The only shining light of this all is that the rust did not fully perforate through (used a screw driver to poke around with literal solid results). It looks to be just some severe surface rust at this juncture and I am looking for some insight from others that have run across similar issues and what they did to remedy the situation. My tentative plan is to use a wire cup brush to remove all the loose rust and attain a solid foundation to paint over. Like many others have before, I plan on using POR-15 to seal things up.
I put fans inside the car to completely dry things out overnight so I should have a good starting point today. What are your thoughts? Based on the pictures, seen below, should I be OK with just removing the rust and painting the floor pans? The saving grace is that they passed the "screwdriver test" so I'm relatively confident I'll be OK.
Thanks in advance for the help.
