Correct lap sealant to use on my roof seams and vents Quantum ws31?

[quantum]

I have a PVC or fiberglass one piece roof, not rubber, on my Class C 2016 ws31 Quantum.

Looking for solid advice on the correct product to use with current factory applied product.

First time to maintain and not sure if silicone or other type of existing seals are applied when built.

I purchased Dicor lap sealant but have seen you tube videos suggesting it will not adhere to silicone?? Dicor states good for all rubber roof surfaces but now not sure !!

Dicor 501LSW-1 Self-Leveling Lap Sealant is what I have

Any tech recommendations on this.

Want to do it right the first time around and also use the right product

Thanks

Silicone based sealants are not used on RV exteriors when built. Your Dicor Self-Leveling lap sealant is the correct sealant to use.

Now if a previous owner used silicon based sealant on the RV you have a completely different problem.

appreciate the feedback. I'll take your advice as a Thor Tec.

Only silicone used was when I had to seal a couple edges on my last trip.

Where self leveling is for horizontal use what would you suggest for around the storage doors and the side trims, speakers etc
