Just been to another shop

They said they can do it no problem

The guy told me that powdercoating will last approximately 4 years on a chassis, and around 7 years if it's zinc coated before hand

He said once water gets underneath the coating it will flake, but not much worse than paint - but that it'd take more abuse to chip in the first place

Unfortunately he only had a blasting cabinet and so wouldn't be able to blast my chassis on site

I'm guessing this is where the problems are?

Right then, below are my current thoughts and the reasons for them

Please step in with alternative suggestions, and correct me where needed.....


After listening to everyone on here I decided I should have my frame powdercoated

I have spoken with pretty much all the powdercoaters near me
They all have blast cabinets, but non of them can blast a chassis
They all said they'd have to get it done somewhere else for me

If I were to get it done this way I would have to hire a trailer to take it to the blaster (50gbp) the blasting would cost (50) the powdercoaters would collect it from the blaster for free. They would then coat it (60) and I would then need to trailer it home again (50)

the total cost to have my frame coated would therefore be 210

I am concerned that the frame will be mishandled between blasting and delivering to the coaters. I'm also concerned about the time frame there will be in between blasting and coating the frame

As I don't think I'll be able to get the chassis prepared suitable I am now starting to think I should seriously consider painting the chassis

If I do paint the frame I will need to decide how to prepare it

The blasters I have spoken with said they will only use etch primer. Non of them would agree to putting epoxy on the frame for me

To get the chassis to and from the blasters, and sprayed in etch will also cost me 210

I do not know whether to get it blasted and etched for 210, or just blasted and left bare (and transported) for 160

My other option is to wire brush the frame and prime and paint it all in my garage


Given the above information, which option do you think I should choose?

Thanks

for me, the answer to that question is, what do you have more of - time or money?

I have more time than I do spare cash right now, but I'd rather go with the better option for the build, and not just because it's a quicker or cheaper option, etc

If I get it blasted it sounds as though it'd be a while before it got coated, and would be at risk to the elements

But, if I were to wire brush it in my garage, it probably wouldn't all be stripped and painted in the same day

......would it be and option to strip and prime in sections, or is that just being silly?

My vote is to have it blasted and then if you have the gear, paint it with epoxy in your own garage.

Happy days!!

I've just found out about a reasonably local coater with a full blasting facility

I'm going to see them on Monday to see what they're about

If they're good I'll go with them, if not, I'll strip it and prime it at home in sections

I feel like I'm finally getting somewhere

THANKS MATE!! Really appreciate you taking time to read and reply to my silly thoughts and questions

Just got to get my welding up to scratch then it's full steam ahead

Went to the blasters I had previously mentioned today

Really impressed with them

Full blasting and coating facilities, no messing about

They said if I dropped of the frame and running gear in the morning they'd have everything blasted and coated by the afternoon

Seemed like they really knew their stuff

The guy I spoke with said he'd be pretty confident that the finish on the frame would hold up for at least 10 years if coated and clear powdercoated over itself

One thing I did see though that's still got me thinking......

When I left they had some sheet metal brackets outside
One of the brackets had a small chip in it and had some surface rust on it

I picked at the coating with my nail and a very small amount of coating came off to reveal a small amount of clean metal

I picked at the coating again (around the newly exposed clean metal) and another small piece came off

I think if I kept doing this I could have removed a lot of coating, all be it only a small piece at a time

The bracket only had one single coat on it though, so maybe a clear coat on top would have helped to begin with, but would most probably still experience the same thing if picked at

So, now that I've found a company that can both blast and coat my pieces, and in a very quick time frame, I need to decide whether to coat the frame and running gear, or just the running gear, and paint the chassis myself

What does everyone think about the flaking I experienced on the bracket outside? Should that be a concern to me?

powder coating is not perfect
it is tougher than paint, so it will resist that chipping better than paint
so the biggest difference is $$$$$$$$$
hows the cost at this new shop you found
i would recomend the powder coating (and i like red)

The blasting and coating is slightly more costly at 250 for a single coat, or 300 with a clear powder over the top

Trailering would only be 50 rather than 100 as it'd be same day turn around, so I could hire the trailer for just one day

I'm not really comparing like for like though, as the guys today were quoting for the suspension and running gear too

All in all, I think they're a good deal

Current plans are;
Body, frame, wishbones, drive train, and motor will be red,
and the interior will be tan leather

I might change a few little pieces, but I think that'll be pretty close to the final scheme

With the current exchange rate, those prices are about what I paid for mine - except the trailer which is a bit high. Do the clear as well as it will keep the color sharp.
