I've been searching for some posts I remember discussing POR-15 and other rust inhibiting body prep primers. Could somebody direct me to that thread or maybe strike up the chorus again.

I just got done reading Oversprays Tech O'Matic and found it very informative. It tuned me into knowing that I know nothing.

It seems that alot of these primers and fillers are compatible only with like brands. Is this the case? Or can we mix and match?

Where can one find a good supplier for body repair supplies (cheap preferrably)?

Thanks -Tim

Zero rust is great for any rusted metal applications ..inner body panels and the like.
I prefer Por15 for underbody work. Its as hard as a rock and its hiding capability is awesome. Be sure to use an etch primer for any new and cleaned metal applications.
Go here to for more answers. The best body work and paint forum I've found.

Thanks Eric - I knew I could count on you to tell exactly what I needed to do, but don't really want to. How was Vegas?

Thanks Petejoe - That was the kind of information I was looking for.

I thought there was a really good post somewhere here on the HAMB that laid all of this out straight for un-educated folk like me.

There have been several posts that wound up becoming sales pitches for various HAMB vendors, me included.

Go to the Autobody Store forum that Petejoe suggested as well as www.zerorust.com. (http://www.zerorust.com.)

Do some serious reading and then come back with questions.
Eastwoods is a waste of money, all they do is relable and double the price.

THE MOST IMPORTANT aspect of of your primer/painting process is going to be to make sure you have the proper breathing equipment. I learned this the hard way thru my buddy PurplePickUp last week. I'll quote his warning to the folks on RRT in full here so you can get the jest of how serious paint fumes are, just incase you have no clue like me.

"I'm writing this as much for a reminder to myself as for you guys. I've mentioned in the past that I've had some bad problems after being exposed to Isocyanates in catalyzed urethane paint a couple years ago and now I'm sensitive to even short exposures. For me, the reactions are nausea, asthma-like coughing & wheezing, chest tightness, fever, bad headache, fatigue, and muscle ache.

Well, yesterday I did some painting and was around some pretty heavy paint fumes at our get-together where we did some thrashing on Denise's car. I wore a respirator most of the time when I was spraying the small pieces and somebody else sprayed the car but there were still plenty of fumes around in the shop most of the day. And last night Jim C, Denise and I put the car back together in the paint booth where there were still plenty of fumes. By the time I left I knew I'd have troubles and sure enough I did. I had a real bad headache on my drive home and puked my guts out about every hour all night long. I was reminded what dry heaves feels like. Today I'm wheezing and real short of breath.

I'm not whining or looking for sympathy. I did what I did and that's that. I know I have a problem and I was a little reckless.

I just thought that I'd post something to remind others to be real careful around activated paint fumes. What I went thru last night and today is something I wouldn't wish on anyone."

Here's more details from George after someone asked a question 

 slocrow wrote:
So George, did I miss read something or did the respirator not work? Maybe you're implying that you only had it on when spraying. 

"I wore a fresh carbon filter respirator while spraying, plus most of what I did was outdoors, but masks don't filter out all the isocyanates. Plus the bad things can still enter your body thru exposed skin and eyes. A fresh air system is the only sure protection. I've got one I use at home. My problem is that I've had an overexposure in the past and now am what they call "sensitized" I get a reaction to any exposure at all. Because of it I have to have annual chest ex-rays and the Dr pays close attention to my lungs and throat.

Isocyanates gas out of the paint for hours after spraying while the catalysts are hardening the paint. They are odorless and real harmful. They are present even after the solvents have evaporated. Just being in the same building where the painted car is curing isn't good. It doesn't affect most people as much as those of us that have had problems in the past but it still is causing damage.

I'm not vomiting sick today but my lungs hurt and I have a gurgley cough and still have a killer headache.

Again, I'm not looking for sympathy but more interested in making people aware. I can't believe the number of people that paint the new generation of paint products without any protection at all. It's just plain STUPID!! "

I sure hope this helps out. It's not exactly what you asked, there are many others that can answer those questions, but when I read that your going to be spraying primer/paint Georges post came to mind. Please heed his warnings

THANKS hotrodladycrusr!!!
That is a great point. We need to be alive after building our rides to enjoy them. I work in the hazarous waste cleanup business and do regular training for health and safety. I looked into the specs on Isocyanates and I'd like to run down some Health & Safety with regards to respirators:

Know what you are dealing with.
1. Get the MSDS from the manufacturer for the chemicals (paint, primer, fillers...) you are using. If you are reading this you are computer savvy enough to get on the manufactures website and get it. They are required to provide this info to you. If you can't find it call and ask and they will fax it to you.

2. READ THE MSDS!!! MSDS stands for Material Safety Data Sheet. It will tell what the bad stuff is, how to deal with exposures, and personal protective equipment required.

Know how to protect yourself.
3. Understand that respirators are not catch alls. Most of us use a Chemical Cartridge Respirator (CCR). These use cartridges that screw into the respirator and basically filter out SOME compounds depending on the cartridge you've installed. The Volatile Organic Compound (VOC) is the most typical cartridge I’ve seen people using. A VOC filter is just a large carbon filter, VOC’s are attracted to the carbon and stick, when the carbon has no more room for VOC to stick to it comes on through. Depending on the concentrations you are working with (pretty high while painting) a cartridge will likely only last 1 day. To be safe change it at least daily. If this seems excessive think of the medical cost somewhere down the road.

ISOCYANATES – The NIOSH guide indicates that Supplied Air Respirators are to be used. This means that the VOC cartridge isn’t going to help you. Supplied air is basically a tube to an external air source. These systems are pretty expensive.

This little bit of info is only a very small part of what we should be watching for, it should raise some questions for you, so please check it out BEFORE you use the products.

I found a couple of previous posts of similar info:

If there is a paint professional out there willing to share exactly what is used and required, that would be cool.
Happy, Healthy Patchin' and Paintin'
