You have a good question on the Dicor....
I actually bought some Dicor from Sunline before they went under. They shipped me 502-LSW white self lelving sealant. I Have tube in front of me reading it and it does not spell out what the LSW means.
So I even went to the Dicor web site.
Dicor.com
They do not mention what Sunline sold me that is a Dicor product. They only list 501-LS to be used during installation.
But I did find this out at other web site being sold
http://www.americanrvsupplies.com/cg...?SearchResults Type in Dicor in the search box
There is
501-LSW
501-LSD
501-LSV
502-LSW
At Camping world
http://www.campingworld.com/browse/p...ts/prodID=5737
They have
551 LSW
551 LSD
501LSV
501LSD
501LSW
The 551 seems to stand for Non Sag type.
The 501 seems is the normal Lap Sealent
The LS stands for Lap Sealent
W = white color
D= dove gray color
V = Ivory color
They all seem to say the same thing for use except the 551 has a Non sag feature. Not sure what is buys one.
The colors options are to I assume match your roof. It "might" be that if they left the color code off, your 551-LS
I have used the 502-LSW and it works well. It flows evenly and self levels out. It looks better 10 minutes after I out it down as it self levels.
Hopefully we have a Dicor expert to help tell us what we have number changes other than Dicor maybe making the product better and needed a new number.
Hope this helps.

PS the bubble, how big is it? I have some small wrinkels. Like waves about 1" wide and in the back corners of the camper. I have heard a small level of waves is normal. But a real large bubble means the rubber let go from the roof materail. Large being many inches in diameter, like 6" plus. I have never seen them, only heard of them. Hopefully some one else can chime on on a seperated roof.
