The seam sealing on my contrail is peeling off… I bought it used and it is a few years old – I have no idea what kind of seam seal was originally used, but they did a nice, neat job – it just happens to be delaminating.
So do I need to scrape it all off and re-seam seal, or can I just slap some more on top, or what? And if I do need to peel/scrape it off (I really hope I don't because that seems a bit tedious), what should I use?
Also, one of my friends said the GE sealant is better than Silnet, but Silnet seems to be viewed as acceptable on here…
