Concrete epoxy coating?

Hello! My husband and I want to re-do the front porch on our 115 year old house. This includes the trim, ceiling and floor. There are many, many layers of paint in poor condition, so we thought it would be best to remove all the paint first. We have never tried to strip anything before, and dove into the project yesterday using methylene chloride. Three hours later we hardly had anything to show for it! We are considering trying a heat gun. Never used one before (kinda concerned about burning the house down). Want to avoid sanding a lot because of lead paint. Maybe a light pressure wash first? The ceiling seems fragile in some spots. A neighbor walked over and suggested we conceal/replace the ceiling with new bead board. Seems like an easier option at this point but we would still need to remove the paint from the trim (wood) and floor (concrete). Any advice/ suggestions are appreciated!

Hi folks, In our ongoing renos, we are looking to recoat an old metal Air Return Grille. We looked at purchasing a new 31x7 replacement, but in all honesty, the quality was pretty poor, with bent/waved edges and felt flimsy in comparison. So, deciding to clean up our existing grille, can anyone recommend a spray paint suited for this type of application? All the best, Cal :)
