Hi everyone, I recently bought my first home, only to find out it was an ex-crack den that’s still being targeted by drug users and dealers trying to settle debts—it’s a long story 
. To secure the property, I’ve installed security film on my windows, but now I need to seal the film to the window frames.
I’m looking for a white structural silicone equivalent to 3M impact adhesive or Dowsil 995 sealant. The issue is, I can only find Dowsil 995 in black or in white if I purchase a pricey bulk order. Since 3M and Dowsil are American products, I’m having trouble finding a similar product in the UK.
Any advice, guidance, or links to a UK alternative would be greatly appreciated! Thanks so much in advance!
