Howdy! First post so far. Bought our 36 passenger bus from a church about 6 weeks ago. Have only been able to work 1-2 days per week on it as it's located a little ways from where we live but we're movin right along with her!
We've got the seats out and the floors up and have also sanded the rust and I spent extra time on the heavily rusted areas. 40 Grit flap discs worked out great! only used 2 and there's still life left in em.
Now here's where I'm questioning myself. Here's what I've got planned:
Clean the floor up with liquid TSP > Follow up with Prep and Etch treatment
Clean floor again > Roll on Rustoleum Rusty Metal Primer
Roll on Rustoleum Protective Enamel with insulating beads
Furring strips/studs > Rigid foam in between studs
What should be done with the side panels that have rust growth? Grind down and treat with Prep and Etch, Seal adjoining pieces of metal with polyurethane, Spray Rusty Metal primer and be done?
Should the holes in the floor be sealed before top coating the floor or before priming the floor and after the Prep and Etch?
Would it be alright to tape around the edges of the insulation with aluminum foil tape or would that trap and moisture created from condensation?
So many questions!!!
