Re: metallic BC won\'t dry...aargh! (long post)

Your paint guy was wrong about the reducer. There is a reason they call them slow or fast. It does affect the drying time.
From your description of the dull spots it seems you are using the wrong reducer. And maybe a moisture problem. Try cleaning your filter and adding a small one at the inlet to your spray gun. You should be able to pick up an inline filter at your paint shop if they sell spray equipment.
If the humidity is a factor then a slower reducer may help.

Geeze Andy......

I want to know what caused it. You can't just give up!!! So get your stinky butt in the garage and figure it out.

Its just not fair to leave us hanging like that.

I agree about wanting to know. I'll find out, but I'm about half irritated with the whole deal now, and I'm gonna cool off - literally and figuratively - and attack it then.

When I get mad at something I don't always do rational things. It's better for me to walk away and come back later.

'Bout the kid...I made him take the MSF course. I even paid for it myself. He's always been a pretty careful driver, now we'll see if that carries over to riding.

Originally he was looking at a sport bike, but didn't like the sound or the looks. Told me he wanted that Harley sound like his dad's bike. Then he added that he's not interested in going fast, he just wants to look cool and attract the ladies.

Like father, like son!

Well...I give up. I'm just gonna hang up the spray gun till fall when it cools off. I was going to get a bunch of different reducers and do some experimenting, but it sounded kinda expensive and time consuming. Instead I just shot another coat of clear over my son's bike which I successfully painted black last month. I'll buff and polish it so he can ride it the rest of the season.

Not often do I admit that something beat me, but this problem wrestled me into submission like a tag team from the WWF.

FWIW, I'm using PPG Stratoclear 2082 and slow reducer in 80 temps in my garage. Works absolutely perfect. Go figure.

Thanks to all you folks one more time.

Good boy you got there buddy.Just read a few posts and it sounded like the places the base wont dry is where you wiped it off the clear,is that it?

Rex,

Sorry I didn't reply sooner. I got sorta fed up with painting (cuz of the problem I'm having with the paint) and stopped reading the Flames Board for a while. Now I'm back!

The darn paint won't dry on any surface other than paper, wood, or other porous surface. I tried it on a bare metal can and some other things lying around the shop. It's gotta be the humidity and/or the heat. So...I'm just going to wait tillthe fall and then get squirting again. I've already got some ideas for my bike and my son's.

Can't wait!!!

Andy

Hey,no problem man,I've been scarce myself lately.I figured out the problem though.Between the moon's gravitational pull and solar flares and the ancient burrial ground you house is built on (any Poltergysts?) you're screwed

I still can't figure it out.I never did ask what you're spraying with either,what gun are you using and do you know for sure there's no moisture coming out of the airline?

Re: metallic BC won\'t dry...aargh! (long post)

AHA! The burial ground! That's the problem. ;-)

Using PPG DBC. I don't think it's water. The paint goes on great...no fisheyes, blobs, splatters. It just doesn't dry.

I've got a friend that's a witch doctor, so maybe I'll get him to come bless my shop or throw around some old bones and smear animal guts on the walls to get rid of those bad spirits. Hey. It might work. Nothing else has so far.

Later,

Andy

Oops,I meant what kind of paintgun ya using?Sometimes I can't type plain english

Kind of doubt that's the prob but it might be part of it if it's got a huge tip in it and it's an HVLP.

Well there’s a lot to read above and I briefly scanned over everything, so I’m sure I missed a couple details. I was going to suggest your airflow, but I think it was covered.
I’m not real familiar with PPG, but what I can do is share an experience I had with Dupont. The local paint store hired an inexperience person & this person was making the paint I ordered for about a month. I would spray everything this person made like I did everything else & it would take days for the paint to dry. At one point I thought the base coat was dry on a bike gas tank and then taped out a design and airbrushed the graphic. Then I pulled off the blue fine line tape and it would pull up the base coat paint all the way to the primer. I never experienced this tape problem when airbrushing graphics, so I was puzzled. Well anyway I was going to do the tool throwing deal myself (I think I actually did), but I went to the paint shop manager with the paint and it took awhile, but we figured the inexperience person was mixing a single stage paint instead of a base coat paint and not even properly mixing the single stage. Anyway I learned a lesson & sometimes there’s a person at the paint shop that doesn’t know what they’re doing.

Stink,
I've read (or skimmed) all the posts. Quite a few comical posts here

.

I have to agree with Dave K. I do not think at all it has to do with humidity. Basecoat will still dry quickly no matter how humid it is.

Here is my thinking...the guys mixed your paint wrong, they gave you either DBU or single stage paint. I bet when *they* did the spraying at their shop, they only sprayed a coat or two. Even an enamel will tack up (to the touch) fairly quickly. I don't think they gave it a "true" test like you did at home and sprayed 3-5 coats. I noticed you said it (the paint the paint supply place sprayed) was fairly dry after a couple minutes...a couple coats of basecoat usually dries in about 1 minute tops.
Even if you "hammered" the base on, it should still dry fairly quickly...

I would suggest ordering another quart, pint or whatever in the DBC and respray this at your house...or see if they have a mismatch pint of DBC that you can take home and do your own test.
I sure can't think of anything else it could be besides the paint itself...
