Undercoating

Getting ready to do some repairs to my tub, which is currently off the frame. Plan on cutting out and replacing anything corroded, but for the most part the tub just has surface rust underneath.

What is the current consensus on undercoating? (type and how much needed if recomended)

I will be spraying it with 2 coats of Eastwood's Rust Encapsulator (which I have already). The Jeep is never garaged and I live in RI. It is not a DD and doesn't see the roads a lot in the winter, unless I am headed out to wheel it.

Well Nelson if it weren't so cold and dark out side I could give you a brand name that was highly recommended to me years ago and I have a stock of it in the barn and if I weren't so old I could remember the brand. So there you have it.

At least tonight I will commend you for sealing it up prior to applying the undercoat. And I can say that the amount to be used is relevant to just how thick you want to apply it. IIRC it will take six or seven of the larger sized aerosol cans to apply what I consider ample to be effective if you were to do the entire underside.

I will make the trip up to get you the brand name tomorrow morning and offer it for your consideration then.

Por-15 is pretty highly recommended.

But i'm cheap and just touch it up with black rustoleom as needed.

I already have and am planning on sealing first with Eastwoods, which is similar to Por-15. Looking for an undercoat to spray over it as a topcoat to hold down road noise and protect it from the elements

...felt I could use a walk and you could use the tip.

I use and would recommend "Tite Seal" Rubberized Undercoating it is a SolderSeal/Gunk product. Two coats.

After applying the first coat you will have a clear understanding as how both the amount of overlap and the distance it is held from the surface will affect the texture. This is a good product. It states that it "seals against rust & corrosion muffles noise" The first part I'm just a little skeptical of, the last I'll confirm.

I used U-POL Raptor to undercoat my fiberglass tub. It's a great product, and very easy to apply. It comes with it's own spray gun in a kit. 1 kit is a 100 bucks, and it covers a 8 ft pickup truck bed. Very durable, too...
