Title: Frame refinishing
Post by: davecara on February 02, 2016, 05:16:41 PM
I'm about to start my resto proper on the 400/4 I'm doing with my Dad.
Can anyone advise what the oe finish was on the frame? Ie paint/powder coat/stove enamel?
And, what would be best to replicate it? It's a budget but and bolt resto (if there is such a thing!) but I don't mind paying out for a great finish.
Any help or advice appreciated!

This is a great debate, I always powder my frames as they are used in all weathers. If going for a black frame, go for satin black as gloss looks too tarty and the satin is a good match.

I recently had mine powder coated black with a zinc chromate undercoat. It looks good and seems to be well attached.
£97 for frame and rear forks including sand blasting, which I thought was reasonable.

£97 seems bloody brilliant seeing as Ive just had one quote back for frame and swingarm in satin for £175!

Not sure where you are mate but the company is  Rugby Powdercoating, 19 Paynes La, Rugby CV21 2UH. I found them really helpful and they're fairly close to me.

You will need all black metal parts done, frame, swing arm, centre stand, side stand, bottom & top yoke, battery box, foot pegs, clock bracket ect,ect. This will save you a ton of hassle later & all will match.

I wasnt going to get the Yokes done as in my experience it doesnt look right, powder seems a bit too thick if that makes sense? I was just going to get the frame, centre and side stands, peg mounts and the headlight and clock brackets. The rest will get painted

I would not powder coat it simply because they were never powder coated.

I think RAL 9005 satinblack paint comes very close.

I kinda agree... zinc, primer, coro-protect undercoat, 2 thin layers satin black...

I'd also fear unseen corrosion pockets building underneath...

I know some Z1 Kawa and some CB750 KO guys that deeply regret to have powder coated their bikes.

Hard to get rid of that stuff once its there.

I just did my frame, Stands and yokes using Hammerite Smooth rattle can and 2 coats and it's gone on really well with a good finish.

Having said that the frame and swing arm especially were in great condition already with only a couple of minor marks and small surface rust.

We'll see how it hold up but I will never use this baby in the wet anyway  ;) ;) ;)

That's the comment I was waiting for! I'm going to get they frame and swinger media blasted and then I'll zinc prime and paint them :)

Personally, I cannot understand why your going that route. Every black metal part on my CB400/4 is powder coated. It is so practical, fuel and brake fluid resistant and after doing 3.500 miles on her last summer, a quick wipe down with the baby wipes and she was as good as new again. Well, better actually as powder coat was not around in the early/mid seventies so I feel this finish is a vast improvement on the original finish. I have another bike that will have exactly the same treatment to ALL black parts as part of the restoration as I know it will last a very long time. The Hammerite will peel like a bad suntan, as I have unfortunately found to my cost in the past, if you get any brake fluid on it and any petrol will make the finish go like a sticky mess. each to their own though.

I must agree with you Paul and going the paint route , at least you can touch in or spray in anytime as with powdercoat not , two pack is very durable to oils etc. And more like stove enamel as they call it , I know people have two packed over powdercoat  ..

I have found that when I have picked up a chip in the powder coat, a quick blow over with the hairdryer 'melts' the coat and the hole fills itself in.

Hey better not take the bike touring a hot country Julie otherwise there maybe a big pool of powdercoating on the floor when you've parked
