Sika522 Caravan and Motor Home Adhesive Sealant Cartridge, Black, 300 ml

Used this as part of a van conversion. It's adhesion is great. I've used it on a solar panel and a roof vent. Worked well and is waterproof. Would highly recommend. Make sure everything is well ventilated when using.

Sadly my 21 year old car developed a leak from the roof due to a rust hole around the sunroof! After much research I chose this product to seal the hole and for good measure all around the sunroof - it is asking a lot really because as you know a huge metal area that gets extremely hot in the sun, then cold is subject to extreme thermal stress and expansion.I am glad to report that it worked perfectly and still is almost one year on with no signs that it will fail either. The flex in the sealant and UV resistance made this the right product for me, also being clear it hardly shows at all - not that one can care too much when driving a 21 year old rust bucket VW!!

Best of stuff always use this over other brands

Came in time and seems to work quite good but as the title says the nozzle is missing.

Good for the job and easy to use with the a good quality gun

Used on my motorhome. One of the better mastics/ silicone items .

We have used this extensively on our campervan to seal installations such as the roof vent and solar panel cable entry gland. It’s easy to apply, provides a good colour match with our roof vent and solar panel cable entry gland, and so far has been waterproof. For the price it’s really not worth messing around with cheaper alternatives.

Excellent. Does what it says first time
