What is the difference between the 501 and 551 versions of this sealant?

Both are non-sag, but 501 is for horizontal surfaces and 551 is for vertical surfaces. Not sure what the difference is. The last letter indicates the color. (W=white)

can this caulk tube of dico r be reseal ed after opening, to be used at a later date or will it just dry out.?

There is a product out there called Little Red Cap (https://www.amazon.com/Little-Red-Cap-Canister/dp/B076CRG6WN/ref=sr_1_3?crid=26RMJPU78XU9Y&keywords=little+red+cap+caulking+tube+covers&qid=1568080303&s=automotive&sprefix=little+red+cap+c%2Cautomotive%2C178&sr=1-3-catcorr). I have had tubes covered for many months and they don't dry out. I have found this at local hardware stores as well.

can i use this to seal corner trim on rv or will it sag to much

Non sagging like the label says.
