I agree with the no's. Silicone should not be used on RV's! It does not adhere nearly as well as products designed for RV sealing. Silicone also leave a stubborn residue that will prevent any other sealant from adhering properly. The residue may only be removed with a specific silicone remover. Dicor lap sealant, either self-leveling or non-sag, is only about $7 a tube, make use of that tube by first locating and mapping out every seam, joint, or screw that should be re-sealed. Clean each location thoroughly and prep with the recommended cleaner for best results. Even Eternabond must be used per preparation instructions for best results.
