Roof Repair: Part 3

Well after some more research, I discovered that using epoxy based resins would most likely melt the foam core left behind from the ABS I had removed from the camper roof and trashed.

The cracked material I had removed took up two entired trash cans, even after I broke it down as much as I could.  I had also performed a closer inspection of the foam core roof and noticed that there were some small grooves left behind around the edges of the roof.

I would need to fill these and and sand them down before I could apply my final Liquid Roof over coating.  The question now would be what materials I could use.

I had recently joined a pop-up camper user forum called PopUpPortal.  After asking a few questions in the various forums, I found a specific forum topic revolving around Coleman camper owners who had repaired of replaced their ABS roofs with materials like Truck Bedliner and Liquid Roof.  

The overwhelming consensus was to use a two part urethane-based primer to cover the foam core, and then fill in the pits with a polyester resin such as glazing putty.

A trip to a local automotive paint specialty shop and a hundred dollars later, I have my primer and resin in hand.  While I waited for a day when I had more time to start that phase of the project, I concentrated on removing the lid latches from the ABS backing.

Nothing really special here, as the latches seemed to be adhered to the ABS with a caulk-like vinyl adhesive.  I am not sure exactly what it is but I am sure I could do a bit of Googling to easily find my answer.

After some simple scraping of the latches to pry them from the remaining ABS backing, I cleaned up the latches and will create backing metal plates for tehm once I finish up the primer and filler on the roof.

More to come..
