Undercoating product to cover rust

As our motorhome ages, we are starting to see little places underneath on the chassis here and there where surface (not serious) rust is appearing. I've been wire-brushing away the rust and then applying a brush-on rust converter product, but I really want to THEN apply a brush-on "thick" black paint of some sort that will help cover and protect the area going forward.

Anyone have a product they would recommend for this? Doesn't have to be pretty and preferably not glossy. Definitely want a brush-on as it is just too hard to control a spray and some of the locations are in tight spaces.

After using the converter( POR15) perhaps an aerosol spray can of undercoating might work

Rattle can bed liner works well.

Used it to overcoat the gap filler foam used to block holes from varmints as they do not care for it.

Use a nozzle from a WD40 can with the hose to get into tiny spots maybe.

I wire brush the rust area then apply Ospho. Once that has cured over night I cover with Eastwood Chassis Black Satin Underbody coating.

+1 on POR-15. It's a little pricey, but works great. I plan to use it on a few places on my mh.

Thanks JaminSamin! Exactly the help I was looking for! Looks like Eastwood has a variety of great products. I'm going to give them a call and let them advise me on the best one to choose for what I need.

POR 15 or Chassis Saver. I've used both and they appear to be the same. Nice part is you don't need to and shouldn't remove the rust down to bare metal. I have a 70 Chevelle SS, under carriage coated with POR 15 decades ago and still looks good. I've also used Chassis Saver on the MH. They cure to a nice smooth black finish. If exposed to sun light they will turn gray but underneath on chassis they stay black.

Product to cover rust

Have had great results using Loctite Extend (spray can)(minimal steel brushing or scraping)then spraying with Rustoleum Automotive Enamel. Seems that enamels are shiny and therefore more impervious to recurrence of rust. Extend does a chemical reaction with rust to create a paintable surface. Have used it for years with very acceptable results.Even on very rusted golf cart battery compartments.
