Today i wanted to make a How to because ive asked so many times on this forum for help and ive gotten it so i wanted to give something back.
We are going to remove rust and most likely never having the problem again in the future.
What do you need:
Angle Grinder (cheap 900w will do) 30 quid.
Wire Wheel Attachment cup: 90mm and 70mm
POR-15 Metal Ready 1 Gallon
POR-15 Rust Preventive Coating 1 Quart
Degreaser of your choice (I use Bilt Hamber Surfex HD)
Respirator mask (This you need) Metal ready is serious stuff, (i felt sick for 12 hours after inhaling a good amount)
Heatgun or Hairdryer
Noise isolating earphones
2K paint or Some form of clear coat (as top coat) (since the POR-15 yellows when exposed to UV light) if you dont care, or if the paint will be painted in non UV light exposed areas, forget this step.
After reading a lot online on what works and what does not ive come to the conclusion that not many rust prevention work like they are marketed.
There was one that stood out of the group (POR-15), a lot of good reviews, fairly easy to use, it convinced me that there in fact are products out there that actually work against rust plus it was easy for me to buy relative to where i live.
So i wanted to try it out.
If you want to read more about how it works, and why i think its the superior product, just google it.
Use the angle grinder and the cup wired wheel to take away some rust (POR-15 FAQ'S
Spray degreaser 10:1 (for me) into the bare metal, scrub it down with a stiff brush.
Rinse with water
Dry with hairdryer or Heatgun (Must be bone stock dry)
Spray POR 15 metal ready to etch the bare metal or use paint brush (Come back every 10 mins to spray or paint more metal ready on the metal, do not let it dry out) 3-4 times
POR-15 Technical Information
read for room temp and Technical Information.
Rinse with water
Heatgun or hairdry to bone dry
Now you can paint, With brush is fine, the paint is self leveling and will make it look excellent.
wait 1-4 hours depending on what temps your room is.
2nd coat should be applied when your finger leaves a mark but no paint has been transferred. (Tacky/sticky)
wait 1-4 hours
Top coat (if you wish)
wait until the next day
You can use it on anything and everything, so far ive done:

Im quite happy with it, the finish is great, very smooth for a brush paint.
I still have all the suspension parts on all sides, spring pan and so forth, + big holes in the rear arches, entire underbody is flaking off and half a rusted sill that needs doing but it seems i might have ran out of time and heat to do more this season. 2 weeks worth of rain is coming and perhaps a week left before snow starts falling.
