Ok, so here's the deal. I finished using the delamination kit. I am happy with kit, but my fiberglass skills are lacking. I would like to apologize in advance for not taking pictures of the process.
I had a long vertical crack in the fiberglass that let water in which led to the delamination. When pulling the fiberglass away, I noticed that the wood sheathing below it had resembled a washboard. I was going to need access to both side of the sheathing, so I cut slits into it so that could inject the resin into it later.
Before cracking open the kit, I did a mock-up of the clamping so that I would have my act together by the time that I was done applying the resin.
I got a piece of plywood that was the length and width of the repair area. I applied pressure onto the plywood at three different spots using three different methods.
For the top, I rested a plank against the top at a 45-degree angle. Since the plank isn't heavy enough to apply pressure, I used a racket strap to pulled the middle of the plank towards the motorhome. The other end was hooked down under to the frame.
For the middle part of the plywood, I used the two open windows that flanked each side of the repair. I placed a 2x4 across the plywood and used c-clamps through each window opening to apply pressure.
For the bottom part, I backed my lawn tractor to push a plank into the bottom of the plywood.
I pulled it all apart and then started my project. The kit was easygoing to use. I pulled out the measuring cup from the box, added 3 parts Resin and 1 part hardener. You now have 45 minutes to finish the job.
I poured it into the syringe and injected into the slits that I cut into the wood sheathing. I then began spreading it between the fiberglass and the wood sheathing. That took several syringes of resin mix. The kit had more that enough. In fact I have plenty left over for next time.
Time to apply pressure. I didn't want my plywood to come into contact with the oozing resin mix. I hung three trash bags over the repair, then placed my plywood sheet. Since I already had rehearsed this, I quickly applied pressure to the plywood so as the crush the fiberglass, wood sheathing together with the resin. I used the 2x4s, clamps in the windows, planks, frame-mounted ratchet straps and the lawn tractor to push it all together.
24 hours later it was time to see the results.
I remove the clamping, the plywood and the trash bags. I saw there was a lot of resin that had oozed and hardened. A few minutes with a razor blade and a sander had the mess removed.
I have taken pictures at this point. The resin did its job, but I wished that I could have pushed the pieces together a little better.
Good enough for a 22-year old motorhome I guess. The important part is that I had abated the damage.
