Great for resealing caravan
best sealant for caravan, I have done around the windows and have seen no damp in there at all. Even done the shower floor and it has worked. Application is easy and spreads nicely, Takes about 30 minutes to dry, Smooth out with finger and your good. Seems to hold very strong.

Excellent for campervan
Great adhesion and sealant, perfect for sticking campervan batons and really all things camper. I tested this by laying a piece of 2 x 1 on van metal floor and came back the next day to see what it would take to pull it off. Well it took about minutes bashing it with a hammer and edge tools. It was really, really stuck on there. Where i could used this stuff and screws for absolutely going nowhere fit, especially if anything was being mounted.

Great product need better packaging
Great product but packaging needs to be more protective - the nozzles had snapped off which doesn't affect useage but one was also missing from the pack of 4 purchased.

Highly recommended caravan and motorhome external sealant
Does exactly what it claims to - this is my choice always for caravan and motorhome external sealant ( for sealing around the external body / panels ). This sealant does 'set' and becomes solid. As always, preparation is key before application. Recommended. However I would have liked a longer 'best before ' date on it - mine was Sept'26, having just purchased in March '26. Good job I wanted to use it quickly
