What do people normally use for this with rattle cans please an etch then a top coat?
May have some time on my hands soon with recent events need to keep busy, I have some pannels to order but I think I might hold back on that expense for a while unfortunately .
Thanks all

Have you got the parts on the bench?

 

They are cast, which is less prone to rust so as usual, preparation is everything.

 

The less rust you have to start with, the better the paint covers.

 

Many use a couple of coats of something like Hammerite.

 

May I suggest that you use a light top coat as it is easier to see under the car if everything isn't black.

With mine I will be using 2k Black.

Rattle cans are ok but not hard wearing so something to think about. Providing we do not get restricted driving on the road then I will be up my workshop doing this very thing over the coming weeks.

Obviously 2K comes with a host of health issues and you need appropriate protective kit.

Hammerite mentioned by Deadsquare is easier to apply but then brings its own problems after if you want to repaint. Normal car paint reacts with it. Plus itโ€™s not as good as it used to be.

Probably not, you can if you want to get 2K rattle cans. Same precautions required.

 

These are a one hit wonder though, once activated you need to use the entire contents quite quickly, you will have time between coats but thats about it.

I am currently tidiying up the rear radius arms whilst changing the subframe.

I have gone for a througher de-grease/wire brushing, then a coat of Bilt Hamber Electrox, followed by some black rattlecan fast dry enamel off ebay.

Time will tell how effective it is!

Have a look on Rustbusters web site they do 2K paints that can be brushed on and seem very tough. I have been impressed with the products of theirs I have used.

Over the years I have tried many paints,rust treatments grit blasting 2k paint etc and none have really withstood corrosion.My cars live outside and are driven all year so may not be typical.The stickers on the suspension of my wife's elderly KIA have more rust resistance than rattle can.Steve..

Ones I've tried and would recommend  are Corroless from here

 

https://www.arc-rite...ose-size-2167-p

 

and get the "S" rust treatment primer from the same place.

 

Rumour says its the same stuff as Rustbusters just repackaged by Rustbusters and the price inflated....... I can't comment though.

 

Farmline machinery enamel in the semi black gloss gives a good satin finish (other colours are available) if you can find some.

 

Dacrylate from here  https://www.spraygun...nt-1-litre.html

 

is also good and you can get the primer from here too.

 

Don't skimp on not getting the primer it just doesn't stick as good, trust me.

 

These can all be brushed or sprayed when thinned to the instructions and don't put it on too thick either just follow the instructions and you should be fine.

I had mine blasted then left in Deox C for a few days. Once rinced off and dried, Electrox zinc primer and 2k painted. Did this with top arms, lower arms, trailing arms and hubs.
