Title: Crank case paint, again!!
Post by: oldboy on December 04, 2021, 02:34:42 PM: Sorry, another paint question. Anyone on this forum used AutoTek sliver/grey VHT engine paint for their crank cases. Tried the Simoniz aluminum VHT on the barrels and it seems a bit to bright for my liking.

Post by: Sesman on December 04, 2021, 04:08:25 PM: Sorry, iv’e not used that product. I thought the same about the simoniz, but having assembled the whole engine and fitted in place it seems to dull down, but remain ‘fresh’ looking.

Post by: oldboy on December 04, 2021, 04:39:58 PM: Interesting!! I may just get a can and give it a go, maybe on the cambox breather cover, something easy to strip the paint off should it look crap or is affected by a few drops of petrol!! Unless anybody comes up with a bad experience with this paint.

Post by: Nurse Julie on December 04, 2021, 04:49:28 PM: The Simoniz SIMVHT31D is the closest colour to factory finish we have ever found.

Post by: oldboy on December 04, 2021, 05:36:43 PM: Must admit looks nicer in the frame than the engine sat alone on the bench. On scrolling through the parts list on Dave Silver site, they actually sells this Autotek paint in Silver/grey??

Have you air cured and then oven cured yet ?

Post by: oldboy on December 04, 2021, 06:03:08 PM: Haven't actually sprayed the cases yet, just the barrels and as yet there just air dried. Is the paint your using the Simonize Silver or the Alluminum finish??

Title: Re: Crank case paint, again!!
Post by: Nurse Julie on December 04, 2021, 06:34:17 PM: At least you stopped and questioned it when you were unsure.
Title: Re: Crank case paint, again!!
Post by: Moorey on December 04, 2021, 07:24:42 PM: Has anyone tried to cure a whole engine at all.
Title: Re: Crank case paint, again!!
Post by: oldboy on December 04, 2021, 08:40:42 PM: Another question for "the nurse", once oven cured is the paint petrol resistant??

Highly petrol resistant but not totally petrol proof but then we've never found any paint that is 100% petrol proof. If you soak your painted engine in Petrol, eventually the paint will lift. Any dribbles of fuel, just wipe off, and the paint will be fine.

Post by: allankelly1 on December 04, 2021, 09:59:22 PM: Has anybody done CeraKote

Thinking of doing my cases in clear or silver as they at the moment are still bare due to other distractions such as the rear disc conversion

(https://uploads.tapatalk-cdn.com/20211204/14c6aa314f49bdd4df683282b27c9a19.jpg)

Is meant to be the biz as lots of the rd boys used this for their exhausts so really good for high temps and super tough and totallly fuel proof

Post by: oldboy on December 05, 2021, 09:50:22 AM: Have made enquiries, but is very expensive. Have seen powder coated cases which look very nice and also because it's thicker so it covers the blemishes in the aluminum better than that Cerakote, which is only microns thick.

Title: Re: Crank case paint, again!!
Post by: SumpMagnet on December 05, 2021, 10:14:09 AM: I always worry about powder coating....both in terms of its heat handling ability over time, and the horrible issue of dealing with it if it cracks or flakes.

I would always paint rather than powder coat a frame, but I can see why people powder coat a frame.

Engines, however, would have lots of raw edges, where every gasket surface was, and thats usually where corrosion starts, working under the coating.

Post by: oldboy on December 05, 2021, 11:32:01 AM: My cases have been vapour blasted and thoroughly cleaned so I'm going the spray paint route with the paint suggested by "the nurse"!!
Title: Re: Crank case paint, again!!
Post by: deltarider on December 05, 2021, 11:43:11 AM: As for our bikes, I don't like powder coating. First, I don't like the looks of it. It is so obvious for anyone to see that a frame has been 'powdered'. Then the problems it can bring when preparations have not been a 100%. Many had 'surprises' afterwards, when holes that should have been left open, have received a layer that involves extra labour to remove. What's wrong with some spray paint? I mean, Honda did it...
Also I don't like to paint my engine. A CB500? Notorious for oil sweating sooner or later, no matter what you have done. And once more... it's so obvious for anyone to see. Also I don't know what the consequences are for the temperature household.
Title: Re: Crank case paint, again!!
Post by: McCabe-Thiele (Ted) on December 05, 2021, 01:04:49 PM: I generally prefer spray paint although I had my frame only powder coated - it was primarily to save the hard work of cleaning the old frame plus it was not that expensive locally - I also chose a colour that that I can touch in if needed as it's a known RAL code - yes it will not be perfect if touched in but doable.

Through sheer luck I have had no issues with fitting bolts etc - the bloke that did the job was a biker so where it was not masked up the powder coat was not sprayed inside holes etc. I would not powder coat any part of the engine.

Post by: Laverdaroo on December 05, 2021, 01:44:54 PM: Al, I ceracoted the 400 lump earlier in the year. Vapour blasted the granny out of it and had the lot ceracoted in clear. Looks great but no so bling as the factory fresh look of the SIMVHT31D

I love it but also love the factory fresh painted motors but this one was to be a more classic finish and we think it looks great. Cost me about 120 for all of it which I thought was rather cheap but I guess it depends where you go (https://uploads.tapatalk-cdn.com/20211205/e69dea2fe79e4c5d12995b6fc7e63917.jpg)
