Jayco used some sort of self-leveling sealant on my trailer, but it did not look like Dicor to me. It stayed slightly sticky and attracted dirt. Then non-deep surface level cracks opened in the Jayco applied sealant and I had white looking cracks in dirty brown sealant. What I did was to use Eternabond on those areas. Eternabond lasts a long time, is fairly easy to apply, and covers up Jayco's lousy sealant. Almost three years later, the Eternabond is still stuck and still looks good.
I felt that the Eternabond would fix the issue without having to remove the old crappy sealant. This would be a difficult job and in the case of mistakes with the putty knife could easliy slice up the roofing material.
To remove the sealant, I'd use a plastic scraper and a heat gun to soften the caulk. A heat gun is easily capable of melting almost any plastic or caulk or roofing material, so caution is advised. Even a plastic scraper can slice your roofing material. After scraping off as much as possible, I'd use naptha on a damp - not wet - rag to remove the excess. Naptha can loosen your roofing material, so just use a bit; it is also quite flammable. I recommend starting in a very small area, and see if the results are worth the effort.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
