OK its been asked a thousand times I'm sure but her goes.

I am about to get my Mini back from the lad who has been doing welding and body filling and I need to get it painted.

It been in and out of his workshop and all of the bare metal areas and some of the filled areas are obviously rusting up again!!!

I intent to rub down all of the rusted areas and let the filler that he has applied thoroughly dry out before doing any spraying so Ill have to clear out my garage!!

The inside has had some repairs and was rusted in areas as well as a new A Panel, patch repairs to the Sills and small areas of bodywork.

I want to ensure that none of these areas rust up again and having read around it would seem that POR 15 is thoroughly recommended on this and many other web sites. Iv'e just been onto the Frost Web Site and a guide on the site suggests prepping with Marine Clean and Metal Ready first (both also by Frost).

My question is should I follow this advice?

I don't have any spray gear but I am more that happy to brush on POR 15 inside and under the arches and under the car but would opt to spray anywhere else, although I just double checked on the Frost Web Site and found this:

"APPLICATIONS
AUTOMOTIVE: suspension - chassis - doors - trunk areas - engine & fuel tanks - rusty frames - floor pans - corroded battery tray"

So this would suggest not to use POR 15 for body panels, if so what should I use instead to ensure a rust proof treatment on bare metal.

Any replies would be most welcomed.

Its because por15 isn't resistant to UV. So if you use it on areas that'll be in sunlight, it'll fade quickly. Thats probably why it doesn't recommend it for bodypanels. Its fine for the back of bodypanels though.

I've recently painted all under my arches and wings and also underneath the whole front end including behind the A panels and right up under the scuttle.

I didn't bother with the marine clean. I just washed the area down with soapy water, then wiped over it with a clean cloth of white spirit, before finally giving it another wipe down to remove any white spirit residue with some clean hot water. I then prepped the metal with metal ready and washed that off afterwards as described in the instructions. The metal ready leaves a good coating thats sort of a milky finish, and the por15 sticks to this really well.

iv done up a fair share of old cars now. and for body work iv always used red oxide primer. it seems to work a treat. i mainly use por 15 for underbody work.. subframes etc. all b

I've never used marine clean either, just use some panel wipe and a clean cloth. Put metal ready on with the spray bottle and keep the surface wet for 20mins or so before letting it dry. I had a chat with a guy from Frost and they don't recommend washing it off with water, I just let it dry and brush off the powdery residue (zinc?). Brush on the por15 with cheap brushes as they're impossible to clean! Keep it off your skin as it'll take a week to come off

I just thought i'd stick with the instructions - If you wash the metal ready off, it still leaves a coating but its smooth not powdery.

I got quite abit of por15 on my hands, elbows and forearms and it took weeks to come off. I tried to wipe it off soon after it went on me with white spirit but it didn't do much and no amount of scrubbing would get it off. Nail varnish remover faded it abit but no much really.

At first I thought I didn't need to bother with gloves and thought if i was careful i wouldn't get any on me. But i've learnt my lesson now though, I wrap up and use gloves now.

i love por 15, really nice to put on and covers really well, and its SOLID!

i just hope actually does its job,

little tip, if you do get it on your hands ect, a pumice stone gets it off perfect, but dont scrub too hard, ive grazed my arm twice in the same place now with one lol

I love POR15 too!

I've been using the Marine Clean to prepare parts prior to Metal Ready and painting. If you mix the marine clean with hot water it is incredibly effective at removing grease and filth - and old paint too!

I've also used the calliper kit to clean, prepare and paint my brake callipers... they look awesome!
