[quote=”rodney79″ post=15170]Isnt the 5120 a faster clear more used for jamming parts?[/quote]
No, it’s just another production clear. It seems thin compared to 5600, I wouldn’t use it as a cut-in clear at that price personally. I use Limco LC4200 for cut-ins & used car stuff. Its (5120) a fast clear but it gives a minute before the kick-off, good for 1-2 panel jobs.
BTW, I’ve never experienced the exact problem your referring to, with die-back its been the whole job or none. I try and give 15 minutes before clearing with diamont, but for me i factor in what color (how many coats i needed to cover) and how much flash i gave in-between the coats. Typically its 5 mins between coats and 10 at the end, the Diamont tech sheet says 15 mins but i’m also usually spraying at a higher temperature then what they base that on.
I’ve experienced the same thing with 5600, as a production clear I wouldn’t expect the same results as a regular clear. They’ve got a newer production clear DC5120 that seems to be a bit better. On the subject of cheap clears, one of the best jobs I did was my brothers truck with a local off the truck product called “champion”. It didn’t require buffing and its held up great over the years. I’ve got great results with the cheap stuff too, I think your mostly paying for warranty with the high end stuff. If you get a bad hardener and f’k up 10 jobs because of it BASF would pay the bill where champion would tell you to eat s***..lol.. It actually happend to my old man at another shop he ran 10 years ago, BASF paid him about $10,000 to redo the jobs.
This is a subject I’ve looked at many times and spoke with chemists about it over the years to. I know PPG states not to spray under 60 degree’s as you can stop the crosslinking process and it will not be reinitiated at a higher temperature.
This is for 2k urethanes, the best understanding i have of it is:
You spray your favorite cold urethane product, since you mixed the hardener in the crosslinking process has begun. What you want to happen is the isocyanate to react with the polyol (alcohol) forming a long polymer chain giving you a proper cure. In colder temperatures the polyol is unable to react but the isocyanate group is. As everybody here likely knows isocyanates are very reactive with water, so the iso group reacts with the water (in the air) when it was supposed to react with the polyol resulting in a non-cured coating.
Also the organic peroxide (used in the hardener) is very reactive and doesn’t last long once added to the mix, it can be broken down before it has a chance to react with the polymer at a cold temperature, another cause of no curing.
I’ve made a few changes to the site utilizing some compression, see if you notice a difference. Sometimes the compression interferes with other things on the site so if anyone notices any problems or has login issues email me @ justin_jimmo@hotmail.com . It seems to me it does help but the compression puts a load on the server with the processing so i’m worried at peak times the site will really slow down, if thats the case i’ll upgrade the server. Let me know if you notice any difference fellas.
[quote=”macioce” post=15057]No slow loading problems for me but when i first go onto the site comes up with 404 error?? :unsure:[/quote]
I don’t like the sounds of that, are you using a bookmark that’s maybe outdated. If you could get me more info about how you reach the site I can see if I can get things sorted…..Sorry guys, I’m a painter then a webdesigner! :compsmash
I realize the site has never been the quickest loading on the net and I’m always trying to improve it when I can. I know there is a major update planned for the framework that is supposed to drastically increase the sites speed. I am thinking of putting a test site together to see for myself, maybe I can have you test it out and see how much things improve for you. I have a pretty highend (well expensive atleast..lol) plan for the server/host were using and I think if theres a problem its likely on my end. Also maybe pay attention to how many users are on and how many guys are on ventrilo when it seems extra slow, I’ve been thinking I may need to get a seperate server for it in the near future… I do notice alot of the high pics/video threads take a while, the latest update I’ve found helps because it loads the page for you to see and does the images afterwards…don’t know if thats maybe caused some problems for your browser either, maybe upgrading if your not using the latest may help.
Added / Restored Some Smileys too!
:weights :compsmash :deadhorse :dnc :hb :rock :hunt :clappy :chair :stoned :cheers
I’m spraying RM Onyx which is basically the same thing. This is how I spray it if its of any help: (theres a few other vids on my channel with water…I know this one i screwed up the editing and it repeats the blend)
Never really used the clears you’ve mentioned. My absolute favorite clear is 923-109 (pre-flexed), the most popular one and I know a few guys here have really liked is 923-255. I’ve sprayed all the RM clears and I’d take 109 over them all. The 5300 was nice but extremely expensive, DC5335 is pretty nice too…Prefer the new production clear (think its DC5120) to the 5600.
UV primer doesn’t really have any compatibility problems I’m aware of. It’s not used for larger jobs mostly because of the cost, it is great primer and sands/builds well. I know Leno used it on his Eco-Jet..lol. You would need a large lamp to cure it all or just toss it out in the sun for a while. The water-based primers are not forgiving like urethane and will crack if you try and build them too much, I wouldn’t really use them over large area’s of filler.
:welc :welc
I think this board software doesn’t like image links that have long urls with “?=xxxx” in it. I usually use imageshack. There is an update coming in a few weeks, hopefully that will be fixed.

I see what you mean now, its hard with so many browsers. The other threads seem ok , just this one when a larger pic is added. I’ll see it I can get it fixed for the IE users.
if your using mozilla, upgrade to the latest version.
