Question regarding lap sealant

[jbres]

Have a brand new Keystone Hideout 27DBS.
I been checking over everything and especially paying attention to my roof, and noticed I wanted to do a little more detail work with the lap sealant. I noticed around a few of the vents the lap sealant has "settled" since the caulking was completed at factory. No problem, I hit it today and now its drying.
My important question is where the roof meets the front of the trailer and where the roof meets the rear of the trailer, it looks to me not enough lap sealant was used. It just seems the whole area looks thin on lap sealant, from side to side.

I realize how to touch up the cracks and small gaps but how do I apply the lap sealant over an entire area span like that to make it "thicker"? The span of sealant is say 2" wide and not sure the self leveling lap sealant will cover over all that....
I used the self leveling lap sealant in the few small areas around vents...

Me too on Eternabond. Btw- you need to use self leveling caulk on roof penetrations and seams. Lap sealant is for vertical surfaces. Glad to see you are keeping an eye on it. The best preventative maintenance one can do with an RV.

X2 on EternaBond. Once you put this stuff on it's there for life.

Putting eternabond over the top of the existing "thin" factory lap sealant?
Doesn't seem it would be a smooth finish with the eternabond

Google EternaBond and use it per directions on the seams. You'll pretty much never have to use caulking again.

on front and rear seams I strongly recommend eternabond 4" seam tape, followed by another helping of dicor on top of that. You will never have to mess with it again
