Poor quality tint poor rust proofing faulty sh*t electronic rust units. Such a liar. Drives customers cars! dodgy as all hell!
DON'T USE THIS COMPANY!

I had an electronic rust proof device fitted by Endrust. The fitting was absolutely terrible. When I looked at the cabling after it was delivered to me, 2 connections had come apart. I had a system that was providing no protection to my vehicle. The cables were just short pieces of wire joined together. One was too short so they just ran it across the engine. When I complained someone was sent out to fix it but was almost as bad. After a short drive again one of the crimps had come apart. Pointless having a system that doesn't work, I had no faith in Endrust providing me with a system that I would be confident would protect my vehicle so I got my local auto electrician to fit it correctly. I will never use Endrust for any product again.
