The best stuff for the job
This is the industry standard for high quality, strong bonds which are reliably waterproof. I use this stuff all the time when I want a waterproof seal, especially in my campervan build where water leakage leads to rust. Don’t buy cheap imitations. It’s dead easy to use, but if it’s cold, keep in a warm room for a few hours before use, this eases the effort needed to get it out the tube. Lean up excess immediately.

The best campervan sealant around!
Brilliant stuff, perfect for sealing around poptop roof canvas on campervan! Stopped any water ingress, easy to work with and apply. Just try and avoid getting it on your skin, its horrible to try and get off!

Miraculous yet infernal stuff
Miraculous yet infernal stuff you can't do without if you own a campervan. It will seal the red sea crack waterproof even under deluge level rain. Hate when I have to use it. Love the results afterwards.

Great for all sorts of jobs
Great stuff, used for fitting windows in van conversion. Excellent seal. Clean off excess, then wipe over with acetone to get a crisp, clean finish. Tip, use latex gloves when using as it can make a mess!

Very handy with very strong grip.
Just what I need to stick most things to our campervan, really strong, easy to use. It has held the solar panels to our van no problem.

Good product
Bought to reseal windows and roof vents on our caravan, great product and easily to use but you don’t need to cut the top of the nozzle as this will allow an even coverage around windows etc.

Me ha servido para sellar la junta de un techo elevable de una furgoneta y genial. Un poco sucio y engorroso para echar sin mancharte y manchar todo, pero se quita bien con disolvente. Quizás algo caro para lo que es...pero sika no defrauda

Nulla a che vedere con i normali siliconi, siamo su un altro pianeta. Caro ma il lavoro lo svolge alla perfezione. Utilizzato per incollare pannelli solari sul tetto di un camper, non si staccano nemmeno tirandoli con tutta la forza che ho in corpo. Utilizzato anche per le sigillature esterne, elastico e resistente! Lo riacquisterei? ASSOLUTAMENTE SI! CONSIGLIATO!
