I take you through fixing rust on my 99 A3; with how to convert rust, prime and spray/blend back into the paint work.
One thing not covered in the video is using filler to fill the pitting, I was happy with my end result but this is perhaps another step I could of followed to make sure the levels were 100% right.
Colour match paint from Paints4u.com
NEXT TIME IT RAINS, IT WILL SHOW AGAIN….

ThanX for sharing yOur knowledge man!…your a Man with an Awesome jOb!
Would you use a self-etching primer for this job instead a zinc one used in the video?
Krust is phosphoric acid which bonds with the steel. You should not disturb it afterwards but apply primer directly on top. A scratch can just break the coating and undo what was done. you may as well have just used the zinc etch primer.
What's the Zinc Etch Primer product that you have used? Do you still recommend this product?
What is the tool your using?
Mess
Does the paint fill in the scratches from sanding and can I use 2000 grit to blend it? That is what I already have.
Uh oh you didn't put clear coat on your door
Primer should be dry sanded to 180 for good adhesion. Your trying to make it smooth to the touch. You want the coats to have something to grab. The end result is good but it might chip off from lack of adhesion.
ARE YOU HAPPY WITH IT??!!
Perfect!
Good job!
Should i pass a metal brush grinder wheel before passing my 120 grid sanding head
why not coat more of the bare metal with the Krust? nice video, thanks.
How will it look in a year or two ?
Very good, just what I needed!
Thanks!
Didn't watch the whole video. But are there something wrong with Audi A3 as it get rusty easily at the bottom of the door/s? Because I'm intested in buying one expect of that problem. Are it all A3 models? Thanks!
Lol. Don't like being a smartarse, but it's not Krust its Kurust (i.e. Cure rust) 👍🏼
holy fuck your good
Thanks for this very helpful video! Can you tell me how long the whole process took? I have a similar area to fix and I'm hoping to at least have the Crust applied in an afternoon.
Nice video.
I wanna ask you if you don't mind where you bought your paint from?
Reason being that I Mercedes fan, but they are rusty as a….
.
Now, I ve got match paint from Halfords and doesn't match at all.
I ll mention that I ve been asked for colour code wich I ve gave it to them.
Regards.
This is awesome and super helpful!
Awesome tutorial! What grit was used for removing rust?
VERY HELPFUL THANKS!!!!!!
ohhh man i hate rust…my benz its full of it….w2o3 …this sommer hope ill get rid of it…
Nice one, I've also got a vag which is a fabia vrs that needs a couple bits touched up here and there, actually plan to buff the sills down and repair them and then add some stone chip protection which it should of came with leaving the factory, nice video will be following your channel
No clear coat? 😀
Nice job mate. I'm assuming the slight difference in finish between the paint sprayed on and the original paint (which had been on the car for a few years I assume) would be minimised by polishing the car? If so, how long after painting would you leave the car before polishing it? Thanks
wow great job
Very helpful. However, after taking off the tape/masked area, you can where I've painted. Its left a straight line. Any advice please?
Hi is this the same for metallic paint work (peugeot ezr silver)
nice video man. helped me a lot
where is the part where you remove the rust?
Your video has helped me (as a complete novice!) to do a good job on repairing some rust on the passenger side door of my Punto. Thanks for your help! 😊
Great video.. thanks so much for posting!
how can you perfectly blend in the paint? can u spray more outwards lighter and lighter and a polish?
its the first time i see rust on a audi
thank u 🙂
That was pretty awesome – I hope its that easy when I try mine this weekend. :0
never seen such a bad job with spray cans in my life, no cleaning, scuffing and you should have taken it up to molding. OK if old car and don't give a shit fair enough.
masking is very important never the less perty good job
why would a Brit drink coors lite
