Undercoating ?

Ok, guys getting real close to putting the Econoline on the road.
Since I live on the East Coast I have to do some kind of undercoating before I drive it on these roads.
What do you suggest ?
Por 15 ?
The underside of this van has no rust and I would like to keep it that way.
And yes I plan on driving this one year round.

Any product will help being you said there nothing there now. The key is to get whatever you use every where there are tight corners and hard to reach place where that salt can get trapped. I have heard good things about Por's , but I think its applied with a brush??? You need a product that can be sprayed to get in those tight areas

Can you spray por ? I was thinking about using a cheap or old gun.

Not sure if you can spray por's??? Maybe someone here knows??

Mcfly,
You can spray POR but you need a very old gun or better yet a undercoating sprayer. If you use an old gun, you need to drill it out to 1/16" otherwise it will clog up. Also it has to be thinned by about 50%. Like applying any undercoating it is messy!!! But yes you can spray POR......

You can (should) buy POR thinner to spray POR 15

If you not spraying it for show, put it on thick. Most important thing is to clean the undercarrage well before applying.

you can by Por 15 kits that include the proper reducer. It will spray well through a hvlp spray gun, I have done it many times.

I beleive POR15 is designed to be apllied to rusty surfaces. I have read on other forums of people using it on new frames and have a problem with it peeling. When applied to surface rust I think there is a chemical reaction which causes the bond.

Since you mentioned your van bottom is currently rust free you may be better of using something else.

Your not so wacko after all. That is a very good point. I have to look into that.

You can buy some other stuff to treat clean metal before you use POR15. I used POR15 straight onto bare metal and it just peeled off way too easily....!!! Not sure what you would use to paint it onto existing paint though....

Oh, and it sprays very easily, but just be careful, as it doesn't dry as quickly as normal car paints, so you end up with a thin mist of the stuff on everything in the garage, including the floor, walls and ceiling.......!!!!
