HOW TO REPAIR TRUCK TOPPER WINDOWS Reseal Leaky Fiberglass Camper Shell<\/a><\/p>\nFrom Lumo’s take:<\/p>\n
The first thing, the hard thing, is to replace a couple of cracked or missing (plexiglass\/acrylic or Polycarbonate\/Lexan) windows. (“Use butyl rubber tape around the perimeter before reinstalling windows. It’s like plumber’s putty but stays flexible forever.”) (“Order from McMaster-Carr or OnlineMetals \u2014 they cut to spec”)<\/p>\n
And to verify how useful the back door of the shell will be (completely putting aside for the moment the question of whether to remove the rear pickup window and be able to wiggle into the cab from the shell). <\/p>\n
With that all theoretically solved, the subsequent thing is what to layer down over the floor, sides, roof, and exterior of the shell. Here in no particular order are some of the options:<\/p>\n
Bedliner coating (Line-X, spray-on polyurethane)
\n“XPS” Foam board up to 2″ (extremely insulating, R-8 to R-12)
\nReflectix bubble foil (probably for the windows, and removable, but also can function as Interior vapor barrier)
\nWindow screens and\/or a ‘fantastik’ fan, the latter of which brings up the issue of electrical rough-in: “Run 12V wiring channels before closing walls. Even if you only install lights now, leaving conduit lets you add outlets\/solar later without tearing out paneling).
\nCarpet
\nTarping, as a basis for either creating adjacent sheltered ‘awning’ rooms, a whole rolling ‘garage’, or both, especially on trips of a week or more)
\nPost layering, installing some form of sleeping platform at least<\/p>\n
Bedliner Application Sequence
\nIf you see structural cracks, patch with epoxy fiberglass filler before bedlining.
\nPressure wash entire interior\/exterior, let dry 48+ hours
\nSand down glossy spots for adhesion (220-grit)
\nMask off windows (if installing new ones first)
\nApply in 3 thin coats rather than 1 thick coat \u2014 prevents drips and ensures coverage
\nCure time: Minimum 7 days before sealing or painting over it. A mid-tone gray or tan balances solar gain better than black, and matching white should also be considered. <\/p>\n
Structural Considerations
\nIf you’re mounting a heavy door\/hatch assembly to the back:
\nReinforce mounting points \u2014 Use backing plates or distribute load across 2\u20133 frame rails
\nCheck hinge rating \u2014 Garage-door hinges are rated for 200+ lbs; ensure yours can handle wind loading
\nStrap\/latch redundancy \u2014 At least one primary lock plus a backup safety strap
\nWind profile \u2014 A tall open hatch catches crosswinds; consider a fold-down flap option
\nThere’s also the issue of how it locks, probably necessitating rekeying (“repinning the cylinder”)<\/p>\n","protected":false},"excerpt":{"rendered":"
