calking exterior seams
What type calk should I use for calking around windows, doors, connection boxes, etc. Should old calk be removed or can I calk over old calk?

Dicor or Proflex rv lap sealant. Do not use any silicone based product as it will not adhere to fiberglass or aluminum. I have never seen rv caulk products at home stores in my area. I purchase it online or from an rv supply store.
I see this stated so many times on the forum but wonder if people read it and then repost it without real experience. I used nothing but silicon on my HTT and never had any issues with it adhering to anything or itself.
Guess Jayco didn't get that memo. A lot of silicone around the doors, compartment doors, and utility connections on our WhiteHawk. None of it is falling off, blistering, peeling, etc. However, any touch up work not on the roof or drip edge I've been doing with DAP Alex Dynaflex 230. Flows nicely, easy to work, and simple cleanup.
