Help in what type of sealer to use on slide outs old stuff is starting to pull paint off and dried out. Tried to fine TremPro 645 toured a RV manufacture in Elkhart In and that is what they were using...
Lots of good sealants available. Sika makes several good ones. 221 is a great general purpose polyurethane sealant...great elasticity as well. 505UV for use around EPDM.
