Removing factory silicone sealant
Hey all!
Winnebago used NuFlex 311 Silicone sealant on all of the roofing joints and vents. The stuff seems to be holding up well on my 2017 Minnie Winnie. My gray tank roof vent just broke and has to be replaced. Of course this is near the skylight of my shower so the sealant for both are connected into one large layer of sealant.
I know the main negative of silicone is that once you use silicone, nothing will stick to it in the event you have a crack. While researching the vent cover I needed, I came across a few videos stating to not use Dicor on Winnebago's roofs because they use silicone and there will always be a very thin layer left on the roof causing the Dicor to not stick. The videos claim to only use NuFlex for this reason.
Question:
1) If the above was the case, wouldn't the NuFlex also not stick, because by nature, fresh silicone will not stick to cured silicon?
2)If that is true, I would have to ensure the roof was properly cleaned for either silicone or Dicor to stick, which means I could switch to Dicor without issue, right?
3) Will Mineral spirits followed up with alcohol along with vigorous rubbing clean all the residual silicone off the roof and allow new sealant to stick?
Thank you in advance for your thoughts and recommendations?
