Glued Down A Solar Panel

I used this to glue a solar panel to the roof of my camper van. The roof was a bit uneven so the sealant was a bit thick in places, it still cured OK though. Over 300 miles and the solar panel is still there.

Cheaper than eBay

The best caravan sealant around.

Product delivered on time and had a long use-by date.

Definitely would buy again as cheaper than eBay.

Best price I've found

I used to buy this for double this price, found this product at Grove and it is easily the best price.

Did the job well and would recommend.
