SikaSikaflex 521 UV – Weathering Resistant STP Adhesive Sealant – Multipurpose – Low Odour – Age And Weather Resistant – Light Grey – 300ml

I had an Peugeot 205 with an after market pop up glass sun roof which after many years started to leak and despite my attempts to revitalise the seals and to try and keep it watertight it simply wouldn't stop leaking. As a replacement was ruinously expensive I decided to look at sealing it up. In the course of browsing a forum I came across the advice that this would be a suitable product to use to seal the sunroof up as it would provide a suitably UV stable rubber type finish to fill the gap between frame and glass.Having acquired the product I popped it into a standard 'gun' with the trigger type mechanism where you keep squeezing on a regular basis to push a plunger into the bottom of the tube to dispense the contents. I broke the metal seal on the tube and screwed the nozzle on having cut a slight angle on the end of it to try and make it easy to dispense the sealant around the edge of the sunroof.The product dispenses fairly well, but in retrospect I should have put some masking tape around the edges of the sunroof and roof as it is very keen on adhering to everything it touches, so you have to be careful if you get too much down as to how you smooth it out. I did wear disposable goves which is certainly a good idea as I got some over the fingers of the gloves in the course of herding it into place.Did it work? Yes, admirably to date which has been nigh on a couple of years now. Once cured it was totally effective in provided the intended sealing affect and has been totally resilient in all weathers.

As described. Very good grip when dry

high quality product, I sincerely recommend

Very easy to use and smooths out great...the gripping quality excellent... only down side for me... after leaving to set for 24 hrs I put some side ways pressure with my cordless drill into the plastic bracket I'd secured the day before the bracket moved so to some up... good to moderate adhesive

Good stuff. Strong rubberised bond, dries like a black rubber pencil eraser, but stronger.Really works well to seal car headlight lenses which is what I needed it for. No condensation what so ever

good

Better than tigerseal

you cant use it unless you have nozzle handy as not one shipped with item. you would expect one after paying £17 for a tube of sealer.
