Caulk

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, any other type you would recommend.

Thanks Bsport

    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.

    Trempro also has 635 as another good option.

    I have also used Chemlinks M1 with good results.

    A good polyurethane, tripolymer or polyether should do the job!
