Painting below cab doors

[jagmanx]

I plan to improve the "whiteness" of the area below the cab doors.
Ie the sills.

So very low down and leaving the doors as they are.
The Renault colour is arctic white but I plan hammerite smooth white.
I have used wet and dry to prepare the surface 2 questions please
No 1 plain hammerite or paint to rust
No 2 does using wet and dry after painting help
Ps using a brush rather than spray cans.
Any guidance much appreciated.
This is the final stage of ongoing refurbishment following on from
1 water ingress repair
2 replacement of the damaged cab rooflite
3 replacing many lights with led.
4 replacing the table/bed leg (dual height)

Personally I would not use a brush but would also neutralise the rust with something like this.

Looks like it's a Renault so isn't the body galvanised?

Thanks Sam, but no rust on the sills but I may choose hammerite paint to rust anyway. Spraying not easy and painting the wheels with a brush has left a good finish.
The area is hardly visible ... I am just being fussy.
Nida is very good at painting.
I painted with the non smooth paint 4 years ago and it is ok bit I think smooth is better

Tis indeed just needed cosmetically

You didn’t used to flatten Hammerite just brush/spray and leave alone. Had to be careful when another coat was applied as well but they make loads of different products now so check tin

Is your water based paint? Can you apply what you are thinking if it is, just a thought may be worth a check

You may as well use margarine as hammerite, clean to steel and use a 2 pack epoxy zink rich primer, then a couple of coats of 2 pack polyurethane or the makers colour.

Sorry Trev, I think that is totally OTT.
I do not have the opportunity to do it.
The area is perfectly sound and the Hammerite I used 4 years ago is good it just needs freshening up.
It is not a boat !
Thanks for posting but not good for me !

Another vote for Fertan. I used gallons of that on my old Dutch Barge.

Hammerite is only house paint with xylene added, zink rich epoxy has a self healing property and perfect for what you are doing, but your shout.

I agree. Zinc rich epoxy has it's uses but not really necessary on galvanised steel.

Any industrial paint shop or boat shop, remember its zink rich, do sand back to bare steel, can be brushed or sprayed, good luck.

The galf may have broken down, and its not true galv <hot dip> but in fact an electroplate a bit like chrome Rob, its also known to bubble.

Possibly Trev. When my mate (another member on here) cut out the windows on his Renault, he left the offcuts with the bare metal exposed outside for a couple of years and still no sign of rust or deterioration so it seems to be pretty good on the Renaults.

Agree about the hot dip process and self healing. My motorcycle garage is hot dipped galvanised and even unpainted looks brand new after the first year. Others who have reviewed them say they still look new after many years.

You can if you wash paint galv, but it must be brushed with either mordant wash for single pack paint to be used, or a acid two pack which must be sprayed if and only if going to use a 2 pack poly on it, galv lasts a long time as is anyway.

I thought about it Trev, but I quite like the look of it unpainted.

I'd get it treated then get it wrapped I did mine myself in a dark grey and now it looks perfect.
