New galvanised chassis what to do????

james0211 · May 23, 2013

Greetings all

Well the time has come and the pot is nearly big enough for a new chassis

so I will be getting a galvanised one for my 110 csw.
the question is what to do with it before the rebuild???

any hints tips ideas would be great eg

t-wash-primer-red oxide then chassis black/wax oil

even heard of getting it powder coated any suggestions on that???

cant leave it as is, because i really don't like the look of it sorry
plus it tells all those little S**T's that steal them

that it has had good money spent on it.

any help would be great please and of course thank you

Powder coat is possible over the galv, the place I go to does lots of powdercoating of galv security fence and pipework.
I'd suggest a satin black and inject inside with waxoyl for the ultimate protection!

i do like the idea of powder coating but worried about if it gets chipped moisture getting in

Thor1950 · May 23, 2013

I would not do it as powder coat will chip and peel from stones,rocks and running in mud. trapping moisture and could cause white rust on galvanize .

Applying/Curing the Powder

Due to the equipment required to powdercoat steel, it is usually applied to newly galvanized steel. It is recommended that the galvanized surface be coated within 12 hours of galvanizing. To promote superior adhesion of the powder coating the following should be considered:

The galvanized steel should not be quenched after it has been galvanized
The surface of the steel should remain clean
When transporting the steel be sure to cover loads and keep dry
If surface contamination has occurred, clean the steel with a proprietary solvent/detergent that is designed for cleaning prior to powder coating
Maximum adhesion is best achieved by using a zinc phosphate treatment before powder coating the steel. Surface must be entirely clean as this treatment has no cleansing action
Preheating steel prior to coating
Use “degassing” grade polyester powder only. Anti-blistering agents, such as polyethylene oxide, can be added to the powder to prevent pinholing and promote good adhesion

Use a primer that will go direct onto galv without it falling off later on, then red oxide, then coat of black. Then waxoil it once its all built up!

Thor1950 · May 23, 2013

need to pickle the galvanize first before paint , use a primer designed for galvanize as any ol primer will not work

i have heard that those paint straight to galv aren't the best in the world???
and you should, t-wash??? first to remove all contaminates this then makes the galv go dark grey/ black to show it has reacted properly then hot soap wash dry then away you go.

No need for any other treatment or coating just spray it over with this stuff, it will protect the chassis from day to day knocks and no one will see it's a galvanised replacement.

T-wash, epoxy or etch primer then a high quality top coat.

The chassis as I bought it

T-wash

Epoxy primer

Finally a gloss black topcoat

What ever you do if you are going to paint it T wash it but before T wash clean it with tfr or similar

Boris113 · May 24, 2013

As has been said before, I wouldn't powdercoat it.

With my galvanised chassis, it was degreased, then had 2 coats of T-wash (aka mordant solution), washed each one off then a layer of etch primer. 2 coats of chassis black followed by the waxoyl stuff that wandershelf suggested.

If i was going to do it again, I would have used a different chassis black that is a bit more flexible but other than that no concerns.

Those direct to galv paints are ok, but only on galvanising that has weathered for a couple of years, it doesn't adhere to new galv very well due to some kind grease that is in the coating.

Where'd you buy it from richards? Best thing i ever did was buying a new chassis!

AlbertDefender90 · May 24, 2013

Got mine from marshland, very happy with it so far

JJbing · May 24, 2013

I got a marsland too, as i didn't want to wait for the Richards, i was hoping to compare see if there is a difference! Enjoy, best mod i have done for a car!

james0211 · May 24, 2013

Nice one thank you all for your advice, does any one know if there any difference in quality between marsland and richards?
and waiting time for a chassis as well?
i would call but out the country at the moment.

For Richards 6 weeks is the waiting time i think, i liked marsland as they deliver with in the week, and i can't have any complaints with my chassis, its awesome.

if a 300tdi you are fooked for fuel tank and towing hitch as they are td5 chassis. Plus marshall uses thinner steel

I've got a 300tdi, forgot to mention the fuel tank, but they don't cost much £40 ebay
