Sealant Question

[Davidceder]

I want to inspect and if necessary touch up the sealant on the roof of my 5'r.
Having never done this I was wondering about self leveling sealant. Will this stuff so loose it will run off a curved section of the roof? I imagine I will need to seal around skylights, fans, vents, etc and maybe the front cap.

Any suggestions are appreciated. Technique, product. Can I caulk directly over the old caulking?

Thanks

Self leveling lap sealant is pretty viscous, about like peanut butter, but if applied to a vertical or sloped surface it will slowly flow down until it sets. It will flow faster in the sun. Having said that, it's not what would be considered runny at all. And when you apply it, it looks like regular caulking, but it slowly spreads out for a few hours.

The simple rule is that if you think you put too much, it's probably good to go.

If you are going to invest the time to reseal your roof, please consider using Eternabond tape. The extra effort is worth the return on your investment as it is more durable and looks better than lap sealant.

Eternabond is something I recommend every camper get even new ones right out of the factory.

Make sure if you are suing sealant you use one that is compatible with your plastic skylight. Some will attack the plastic.

Second the eternabond option.
