Help Needed Applying POR 15

I have dropped the belly pan and wire brushed the frame members on my 66 Trade Wind. I don't have very much rust. Yea! I can't sand blast it in the shop I'm in.

I need your good tips on applying the POR 15 by hand. It slmost seems like mission impossible. POR 15 instructions state:

1. Marine clean by spraying say 3 to 1 on the frame. By hand! The Airstream isn't oily or greasy, but the instructions say to spray this degreaser on the metal. Then I will have to wipe it off with a wet towel as I can't spray water in this shop either.

2. Metal Prep by spraying by hand! Leave wet for 30 minutes! Keep spraying! I'll have to wipe it off with a wet sponge or towel. There are lots of nooks and crannys in an Airstream frame as you well know. It may be several days before I can get back to begin POR 15 painting. Is that okay? I'll have a bad case of wrist tendenites befoe I'm done squeezing that hand sprayer.

3. Brush on POR 15 with good ventilation. Is a fan good enough? I'll wear my mask. I am working under my trailer with about 2' floor to frame. Second coat within 5 hours. I estimate it will take me 3 hours to brush coat the entire 24 foot frame. "Humidity best at 50%." I'll be lucky to get 30% during the winter months around here. The shop is 60 degrees F. It is a 80,000 sq foot shop that I rent 10,000 feet for the winter monthis. So it is a big area and the furnace runs a lot.

Do folks do sections of the frame one at a time? Let's say I can get about three frame "bays" done at a time using the leave 30 minute wet instruction for prep, and 5 hour dry instruction for POR 15 2nd coat.

Doing a Model T with POR 15 seems a whole lot easier than trying to do an Airstream frame on my back without runniing water.

Your experience would be helpful.

Hey David--you and I are in the same phase it appears. I'm doing a shell on resto, in NC where we are having 70 degree temps but 100% humidity. I did the marine clean & metal prep earlier in the week. To answer you initial question, we are doing the front & rear sections. We will be brushing it on, but if you have access to a sprayer you can probably get it done faster.

Thanks for your reply. I'm thinking a paint sprayer would cover me with POR 15 as I just don't have the room to get good angles and distance with a sprayer. I read those who apply with a brush ought to use a foam brush.

I may have to do the frame in sections to get the timing right. Four to five hours dry time between coats of POR 15 will make it a very long day.

How have others applied POR 15 to the frame with the body still attached?

Have fun with your renovation. Old Airstreams make great projects.

David

You could buy a cheap garden sprayer.

POR 15 gets everywhere

I did my Trade Wind with a brush, I have used POR on alot of auto restorations also, Make sure you cover anything you don't want it on, including yourself. It tends to get everywhere you dont want it. It is a great product. Take your time and have fun. Your frame looks great in the picture.

I think you could get by with just wire brushing and put the POR15 right on top of it without prep. If it is old weathered metal and paint then you don't need much prep. If you have new metal that maybe preserved with oil or other slick surfaces then they need prep. The worse the condition of the metal the better the stuff sticks. If you are going to all the prep trouble you can just use regular paint. The whole idea behind POR 15 (Paint Over Rust) is to make it easy to use.

I'd called POR15 direct and see what they say. You want to do it right the first time. Keep your head on the creepers headrest as much as possible or your neck will get strained before you know. Been there done that and no fun!

Maybe I will give POR a call and ask advice. I imagine they will say follow the instructions. My frame has been wire brushed with a small power tool. Maybe 10 hours worth of work. Wow, what a dirty job! The wire brush took a lot of the dust and surface rust off. Where the tool fit good, I have shiny metal. There are nooks and crannys where there is still dirt and surface rust, especially the outriggers and frame corners.

Perry, your idea is a nice throght. POR says you can paint directly on sand blasted surfaces. I have 48 year old "seasoned metal". I have brushed most of the dirt and surface rust off of it. I would like to brush POR 15 directly on to the metal without all the wet prep stuff. I'll call POR 15 and see what they say.

I wire brushed my 86 frame and then used rattle can Rustoleum primer and paint. Cheaper and easer, but I have no idea how it is holding up. POR 15 is a proven product.

I have used POR 15 on a number of projects, it works great, it is messy. No matter how I cover myself I always seem to find some product on my hands and it does take a good week for it to be completely gone. With that the down size I would use it again.

No matter what paint you use, you will need to clean the dirt, fiberglass, mouse poop, and other funk off the frame. The cleaner the metal is the better bond the paint can make. POR 15 Worked great for me. Even the drips get rock hard. I had to do the same thing, wash and wipe the frame down. The Marine Clean is just a de greaser. Metal prep is for new metal or is your painting over a smooth surface you want to scar up. The wire brush should have scared it up plenty.

I second coated the next day. No problems so far. I painted over old rusty frame, and new galvanized steel.

And yes, once thus stuff dries on you it has to grow off..

Thanks Silverflames. Your preped frame kinda looks like mine after I cleaned it, but yours looks better! Most of the funky stuff is cleaned off. POR likes surface rust. And the stiff wire brushing certainly left scratches and swirls on the surface of the old metal.

I hear ya about getting it on me and my clothes. Maybe I need a HazMet suit. I do have a respriator, fan, face shield, long rubber gloves and coveralls.

I'm thinking I will paint it with POR 15 as it sits.

Just a FYI that is the painted silver Por 15. If it sits in sunlight it will yellow in about a week. But yes tough stuff. I used a full face mask, long gloves, t shirt, and old pants. I just rolled down my selves at work for a week. It was mid summer in Fl so that was all I could stand to wear.

There is some stuff that is similar to POR15 called Aluthane and it can be used as a top coat. It is Aluminum filled polyurethane.

I'm thinking I'm going to apply POR 15 directly to my wire brushed frame.
It has surface rust on it, but otherwise not too bad. I'm thinking about it because I'm lazy!
