Resurrection and development of V8 Project GT1

[mike_sekinger]

Brushed on.  There is a POR-15 Top Coat that will be applied before things start to go back together.

This is a 'one-time Gig'.  Not doing it again 🙂

2nd coat done.... time for a Whisky !

I second that 😀

[Mightymetro]

It looks a really even finish for a brush finish 👍🏻

Is that your citric acid tank in the background? 🤣

[mike_sekinger]

HAhahahahha…. That's one of Gill's many projects.

[mike_sekinger]

More parts prepared ready for going back together.

Metalwork for plating on the way.

[mike_sekinger]

Seized split spacers - not a job that I had been looking forward to, but in the right frame of mind to tackle it today.

First side took two cuts, second only one.

[cweeden]

@mike_sekinger have you blasted those items clean or is it another example of citric acid at it's best?

[mike_sekinger]

Both were blasted this time.  The trailing arms are being galvanised and the hub carriers will probably be left as is.

It takes a lot to bring me to my knees..... but I'm BROKEN !!!

Preparing to apply the POR-15 Top Coat and while inspecting I was unhappy with some areas of the surface finish.  I challenged the coating and it just peeled off !

I challenged a little more and honestly the adhesion was super-crap.  I followed the guidelines and did a pretty damn good job of preparing the chassis, so I don't know where it all went wrong.  The whole lot is coming off again...  I'm not impressed and now re-consider the whole paint coating route.

[Barrykearley]

Oh my gosh - chap have a whiskey - make it a massive one. 

Retreat, regroup, drink more and beat it 👍

[sailorbob]

Very disheartening. Did you use Metal Ready as part of the preparation? If so, maybe it needed to be treated longer to get a sufficient zinc phosphate coating.

[tomcattom]

Jeez I feel for you looking at all that hard work flaking away.

[mike_sekinger]

I did indeed use the Metal Ready prep.  The chassis got left a full week before the coating.

I kind help feeling that I did something wrong.... but I cannot see what it was.

[steve930]

Sometimes paints don't bond properly until they're fully dried & cured

 

[sailorbob]

POR-15 works best on rough, plain steel and can suffer lack of adhesion on other metals and galvanised steel. I assume you did not immerse the whole chassis for a week in the Metal Ready and the week was the time left after treatment. The problem is probably due to one of the following:

1) The suggested 30 minutes probably wasn't long enough to get a zinc phosphate coating.

2) An excess of zinc phosphate was built up.

Application of Metal Ready can be laborious when trying to get complete rust removal and / or a zinc phosphate coating and I have never found it particularly good at removing mill scale.

Mike, sorry to see all these hours gone, but better now than later. I would probably get it re-galvanised.

Kind regards,

jacques

[mike_sekinger]

Off for plating

[cweeden]

Sorry to see the paint problems on the chassis Mike, I think that would break me too and I hope the next attempt goes much better. 

cheers

Time for the radiator pack, now that the rubber mounting bobbins and washers have arrived.

[Barrykearley]

Love it when bits arrive 😀. I actually managed to intercept two deliveries today before the missus 😂

[mike_sekinger]

No A/C, so just these two up front.

I've used products from a company called Buzzweld. I'm really impressed with the finish.

[Rolls]

That’s highly unusual. I would contact them.

[mike_sekinger]

My son sent me some footage of my breakdown.... amusing to watch, but at the time I was super-pi##ed.

Apologies for the foul language but you can see that there is simply no adhesion.
