Finished up some pretty serious delamination repair. I went with Composet SLV and it worked excellent. I think it is much better than West, which didn't seem to last of a previous repair. Plus the Composet people did a good job in walking us through the process. More expensive yes, but still a fair price given the alternative. The problems all started in the running lights, 4 out of 5 where leaking. Fixed the delam, replaced the lights and gaskets, then caulked with Sikaflex that I got from them.
For reference the website is www.delamrepair.com. So bottom line is West might be okay but the Composet SLV is the right choice.
