Started to prepare the car for painting:


Picture before I started.

Problem is that it has been "prepared" a couple of times before and surface rust has got a hold of the new panels. I've hand sanded back to clean metal, but there are still pitted/stained areas. I don't want to use too heavy a grit or a grinder for fear of creating even more work getting the scratch marks out.

The plan is to etch prime the new panels followed by a couple of coats of primer, then rub back to a smooth surface before more primer and finally the top coat. Hopefully this will get rid of the pitting.

Is this a sound strategy or should I be treating the rust and dealing with the pitting first?

Personally I think I would treat it with ku rust or similar first. Then acid etch prime as you say.

last thing you would want is for it to come back through when its nice and finished

Done now needs redoing lol

Yeah get shot of rust first. Didn't do it with my Jet Black years ago and it started looking shit pretty quick.

Had to be painted again.

If something is worth doing, it's worth doing half of.

You want fe123 and some phos clean.
It won't come back

Thanks guys.

I'll see what inhibitor I can get in the morning.

I found a bottle of Jenolite in the barn. I think I must have bought in the late 80s!

Turned all the rust remnants in the pitting to a black colour, so seems to have done its job.

Etch primer and 1st layer of high-build primer now going on.

I wouldnt put acid etch on top of Jenolite, infact I wouldnt even have used Jenolite, just a good etch primer

I seriously doubt it!

I read various opinions of Jenolite online, none of them consistent. A lot compared it Kurust as suggested above.

I applied it, let it turn the pinpricks of rust black and then sanded it off. Then etch primed the panel.

I'll report back in a few years on the success or otherwise.

mm have a lot of rust comeing out in my club sort f want to do something but i know its going to end up a much larger job than expected so keep putting it off! its mostly in the seams and gutters! the worst place!

I left a little bit of black pitting on a VW I repainted 2 years ago.... its coming back :(

I seriously doubt it!

Is UPOL Acid 8 any good Paul?

Tbh I dont know. I did use it on my aluminium bonnet about 8 years ago to get me out of trouble and its still on it now with no problems. When I do a whole car I prefer a good make - I used a RM product before but cant remember the name of it

I seriously doubt it!

The Upol stuff seems pretty good, I quite like most of their products to be honest. I've just bought some raptor for the floors inside my car.

We used a spies hecker epoxy on andys shell. Apparently keeps the rust at bay better than the etch !! It's very expensive tho
