i also had a windscreen fitted when i was down in rugby working,and no it wasnt oem glass but the van turned up and the guy seemed professional.i was out on site at the time as i was putting a new bridge in over our newly laid railway,kept popping back to check on the guy and he was working fine.after about an hour he said he was finished and i could not beleive my eyes,there was black sealant everywhere.i swear to god i nearly knock him out on the spot,i couldnt beleive this f*ckwit had the cheek to even think about leaving my car this way.(iwas pretty irate).so made him take all the interior trim off to clean with turps and then i notice the windscreen wasnt even in right.an hour later he says he;s finally done(watched him like a fat kid watches cake)and finally signed sheet.2 days later back home in manchester we had some sun so i thought id wash the car.around 21 hour later i start on the inside and see a massive stain on the a pillar passenger side,when i get over to inspect it, it f*cking soaking wet.the windsreen was leaking like a f*cking teabag.straight on the phone to cowboys r us with a few choice words,and also on to insurance to let them know how good there recommende repairers where.next day back in rugby,the firm come out to meet me(different guy this time)which iwas upset about.all he did was dump a load of sealer around the leak and said phone us if you get anymore problems.needless to say i told him to go suck my fat one.but honestly even when you watch them like an hawk they still f*ck up GOOD LUCK .....ps sorry for the rant but it still gets my back up..next time id go straight to the dealers and get the insurance to pay them
