(2,500 characters)we'll talk a little bit about pressure so I I typically I'm spraying with a 515 tip U my pressure is typically at right around 1,600 to 18800 PSI the higher the pressure the more um atomization uh the more Kickback you're going to get from the door more likely you're going to have overspray so don't run your pressure too high if you don't have a pressure gauge on your sprayer and you don't know that's going to be difficult I have a pressure gauge at my sprayer so I know exactly the pressure I'm running as soon as I spray the door um another thing is is you could get bridging from weather strip to door and that could be a big uh problem if you don't score it so we spray the door rise it and then um and let it dry up another question I do get a lot is do you spray or paint the door that's behind the weather strip that you can't see we do not paint that and I I get that question a lot the reason why is In the Heat of the day you could get your weather strip tacking to that part of the door which has happened to us we've actually had garage door openers uh rip right out of the door because the door weather strip tacked to the painted surface on the other side we just leave it powder coated your weather strip will never stick to it and it's the only time you'll ever notice that is while the door is rising up this on the door behind is white this is a a kind of like an off- white so you wouldn't even really see the difference anyway anyways if the door was previously a brand new knew was black and now you're painting it white you could see that but it's never been an issue I've never had a customer ever question it and so we don't paint behind the weather strip so I'm going to get over here we're going to spray this door uh we sprayed the stacco I'm not worried about overspray getting on the stucco because I've got the the trim that blocks it and it keeps the the overspray from kicking you know outward right there I'm going to be spraying I'm coming down the line I'm overlapping 50% I always start off my first PA and I um started off twice because as you're moving along the line you're overlapping 50% and that first pass wouldn't get um two coats on it and so it'd probably be light on where it is um the color that the stucco got on there so two passes to start two passes to f um finish uh 50% overlap in the middle and it's going to be coated make sure um this is one and done we spray um one coat on here overlap 50% and the garage door is done so here we go we're
