Exterior seam sealant

[MDC's First]

Its that time! There are a few areas showing signs that its time to reseal all the panel seams on my 2015 38FLSA. Drips between awning and side panel where awning is mounted. I've searched the site for best product and process and can't find anything addressing this. I feel I must "cut" out all the old "caulk" and reseal. Seems like it'll be an extremely time consuming process but better than the alternative! Can someone tell me the best product and process to use? My RV is stationary and in full sun. I have to use clear or black. Thanks

Thanks! I see they have several products. Is there one in particular that should or should not be used? Can it be applied over the old?
