Resealing/caulking everything on the exterior of 1988 saturn

So with trial and error I've learned too late how to properly caulk using soapy water, which means I'm going to need to remove my newly done caulking and redo it. (thankfully I didn't get far).

I want to reseal any holes I see, the awning connections to the siding, the windows, and any other vent or any other cut out area needing it.

I previously used dap clear 230.

I want to take the windows out of put bukly tape under them and then reseal them once cured with the caulking. Same thing with any vents that I need to take out to inspect inside. The water input door, electrical door, and the hose input circle thing I'll leave on but caulk around.

I also want to take the corner metal molding off and seal the corner with dicor seal-tape. Replacing any rusted screws and staples, using the tape over the edges and then with caulking on the metal molding rescrew it in and put the trim over.

I'd love any advise on whether or not these are safe things to do with my rv. I know the previous owner maintained it well but it still had old water damage that I don't want to happen again.

I'm maintaining and repairing every inch I can so if there is a forum I can be refered to as well on how to do everything that would help.

Thank you!

Is that the right way to do it?

Just an add on. I'm planning to do this with any vents and window I'm able to. Same with the corner molding; putting dicor seal-tape on the edge to seal.
