The shroud on my roof air conditioner is cracked. I was wondering if anyone had the same problem and repaired theirs. If so, how did you repair it? I was thinking of something like Gorilla tape (a kind of duct tape). Has anyone used that to make the repair?Thanks.

Never used it to repair an A/C shroud...but Gorilla Tape is serious stuff. It is stronger and stickier by far than duct tape.Aside.. completely replacing a standard RV A/C shroud is an easy fix and not all that expensive.Good luck with it.

I never had any luck with tape holding up for any amount of time.I have had good luck with fiberglass cloth and resin. I rough up the surface with 80 grit sandpaper before fiberglassing.

When I cracked mine I taped it form the inside with some eternabond tape I had left over from a roof job. Worked well.

I've been using West Marine Six10 Thickened Epoxy Adhesive for all types of fiberglass crack repairs with excellent results. This stuff can be put onto a vertical seam and not flow downhill. Clean with Acetone or similar and maybe roughen with sand paper, etc.It's a two-part epoxy that comes out of the nozzle already mixed due to their unique nozzle, but you can also just squirt it out without the nozzle and mix on a flat surface if desired. You may be able to find a two-part epoxy of the thick type in a big box store, too. I think that would work for you, too.

If you go the epoxy way I would take a small drill bit and drill a small hole at the end of the crack and this will help to stop it from traveling more. You could epoxy a light piece of plastic on the inside along the crack to give it some extra support.

Anyone repaired a cracked AC shroud? | Good Sam Community

I used a thin piece of flat aluminum plate about two inches wider than the crack was long and used white pop rivets. ( the plate goes on the inside.) You can't see the white rivet heads from the ground.

They are $75-110ish on PPL. Why not keep your nice motorhome looking nice?

Eternabond worked fine for us too.

Here's a link to a post about someone who used plastic model glue from Hobby Lobby.

I was resealing both of my units this last weekend with new foam, and cleaning the 'radiators' ready for the heat of summer.

I noticed that my rear cover had a crack so I just cleaned it inside and out with lacquer cleaner and then used the aluminum HVAC duct sealing tape that I was using to reseal the AC on the inside and outside - seems to hold pretty well.

Replacement shrouds seem to be pricey and as long as the rest of the shroud is intact and not crumbling, a quick repair seems to be fine.

I use fibreglass w/cloth and spray paint w/white (on inside). Works great and saves $125 for a new one!!!!

Eternabond or Gorilla tape will do the job. Just remember that the reason it's cracked is that the sun's UV rays has made it very brittle and it will have to be replaced in the future.
I think it's time to replace it for safety sake,don't want it breaking apart going down the road.Don't ask how I know about trying a repair job. :SAfter time they get as brittle as glass.

Our previous MH's ac shroud was getting brittle from sun exposure. I ordered a replacement from PPL...inexpensive, fast delivery and a perfect fit. Once the plastic starts getting brittle, more and more cracks will start appearing.
