best clear sealant for painted rv sidewalls

I have a Tiffin phaeton motor home and know that Tiffin uses residential grade silicon. I would really like to use something that will adhere better. Please advise. Thank you.
  • Try Dap ALEX PLUS 35 year from Home Depot. I started using it 10 years ago on my MH. It sticks, seals and stays pliable and it's cheap. The clear works much better than the colors. Had an old time RV body repair guy tell me about it.

  • I used ProFlex a couple of weeks ago and it is still tacky to the touch. However it does seem to sealed everything up nicely.
  • Clear polyurethane caulking is much better than silicone for exterior sealing. It is available from many home supply houses or online. It is available in standard caulking tubes.
  • IF they used silicone then NOTHING will adhere again until ALL silicone has been completely removed and then a silicone remover used to get rid of residue.
  • Dicor or Proflex
    There are two kinds...self-leveling for the roof (horizontal) and regular for vertical applications.
