5th Wheel Seams, Hair Line Cracks?

Have hair line cracks on some of the Gel-Coat seams on our 5th wheel. Wondering what kind of caulk should be used? What have you folks used on your RV seams?

Thanks for your help.

  • I wouldn't use silicon. If the cracks get worse and you decided to have them fixed, nothing will stick to it. Go with a polyurethane based caulk of some kind.

    B.O.
  • I had some on a 07 Quantum. Dealer told me to use pure silcone and work it into the crack. Also keep fingers wet so it will smooth out. If the crack is left there water will get into siding and cause delamation.
