W4 Mastic Sealing Strip for Caravans & Motorhomes White 19mm – Weatherproof Sealant for Overlap Joints, Awning Rails, Roof-Lights, Window Surrounds & External Trims, Durable & Easy to Apply

Bought this to replace a caravan skylight. Really easy to use and prep before fitting, just cut to the required length. The sealant tape is pretty flexible which allows you to follow contours etc.Thoroughly recommend 👍

Great stuff

This stuff has successfully sealed the front joint on the caravan as the original had broken down and was no longer sealing the joint. The unfortunate thing is that it is sticky on both sides so is picking up all sorts of stuff that I can't wipe off again. I suppose the main function is to seal the joint so from that point of view it works well.

Brilliant!Our roof vent was leaking at the seal, so used this and its held tight for over 2 years now- no problems!Recommended.

Good reliable product, used many times.

Super adhesive sealing tape, just enough to do both roof skylights on my van conversion, expensive but does the job.

Obviously bought wrong thing. Wanted to stick some perspex to window frame to keep out draughts for the winter. This was stickier than treacle couldnt detach myself from it! Sure in hands of an expert would be fine but didn't have a caravan to practice on!
