I applied a second coat of Henry's and it used just a little more product than the first coat. I did get two coats with a single gallon and maybe a cup full left over. I used a 3/8 nap roller for smooth or semi smooth surfaces. At times the roller didn't want to roll, just slide but I did get it on pretty evenly. My trailer has a 1 piece aluminum roof so I tried to be extra careful around the roof edges and around the roof vent. I took more pictures!! Hope to figure out how to post them soon!!!
It clouded up now so I anxious to see how it looks in good sunlight.
Question. Is it a problem to add another coat in a couple of days if I decide too??
