Question:

I have a 2007 Phaeton motorhome with a fiberglass roof. What material would you recommend for sealing between the end cap and roof, around vertical windows and the outside seam between the side wall and the roof. I believe your Alpha systems 1010 or 5160 may work but I dont know the difference between the two. I already understand the difference between self leveling and no sag material. Will either of these work and if so which would you recommend, thanks.

I spoke with the Alpha Systems and they stated that the Alpha Systems AlphaThane 5160 Non-Sag Sealant for RVs - Black - 9.8oz - Qty 1 Item # AL73KV should only be used when installing a whole brand new roof membrane. The Alpha Systems 1010 Non-Sag Sealant for RVs - White - 10.3oz - Qty 1 Item # AL28KV can be used any time.
