Sealed my windscreen first time good product

This product solved my leaking windshield perfectly. Had been annoying me for a while but this did the trick in my case

Gave 3 stars as was returned back for a refund as wasn't suitable.

Worked ok

Did a great job of resealing the window on my Z4. No issues when applying it. Good bond.

Used for sealing windscreen

61 plate Volvo xc60 with wet front passenger footwell. Took windscreen trim off and used two tubes around two sides and top of screen. V pleased, footwell then dry but after 2 months it’s v wet again. Took the car to two different specialist vehicle window fitters. Both said the same ‘worst decision you could have made using silicone’ Apparently silicone can etch into surfaces and unless it is completely removed by abrading off the top coat of paint and a specialist primer used, new bonding agent will not stick.Apparently the original screen bond was failing and now unsafe.Going to replace as not a lot more than refit, but costing more due my use of this sealant.
