Recommendation for chassis treatment please

[PV7998]

I'm hoping to tap the collective knowledge of PH here.........I've just got the Cerb up on the ramps and the chassis is in good order (at least the bits I can see).
It's been coated at some time in a black chassis paint, however in a few (and it really is only in a few)places this has come off and there's now small patches of surface rust.
It's these few small areas that I want to clean up......I've been looking at some of the products on the Frost website
http://www.frost.co.uk/catalogsearch/result/?q=rus...
Has anyone used any of these?.....I'm looking at using some of the POR15 metal ready on the patches then painting a slightly larger area with POR15 paint.
Anyone here done this - or done it another way that works?
Previous cars I've just wire brushed and sploshed a bit of hammerite on.....I just think that to do the car justice I should put a bit more time and effort into it.

POR is good stuff. Just don't get it on skin or cloths - it doesn't come off.

Thanks.....there's a "starter" kit which looks like it should be enough on their website for about £15 so I'll give that a try.
I'll make sure I wear gloves!

I've just done some of my Tuscan chassis with 121 Epoxy Mastic. It's easier to use than POR15 and has done well in tests.

This is new to me but it looks less complicated although more expensive for small areas........have to read up on it.................thanks

Short update for anyone that's interested..........

In the end I used a POR15 Starter Pack from Frost, I followed the instructions pretty much to the letter,
I cleaned off the existing with a wire brush attachment on an electric drill (messy). As I was only doing small patches on the chassis I ended up painting the top coat of POR15 over some of the existing powdercoat/underseal, but at least I cleaned the surface rust away and covered it.

O/T

A colleague came to work with his forehead red raw (and grey) one Monday morning. He'd got POR15 on himself while painting the underside of his Scooby and left it. Washing and scrubbing did nothing to remove it so he took to scraping it off with a knife. Largely unsuccessfully. It took a couple of weeks before it came off naturally.

A couple of weeks of ribbing, obviously!
