Simoniz Engine Enamel

(1/3) > >>

tom400f:
I've used this on my caliper and the finish is nice. My question is do I need to bake it and if so at what temperature and for how long? If it was on an engine it would get hot of course, so some sort of heating seems sensible .

The can says its cured after 24h and is good for 120C. Anyone know what that means?

SteveD CB500K0:
120°C is nowhere near enough for an engine paint.

Are you sure it says "engine paint"? - are you sure it says "120 degrees"?

tom400f:
Hence my request for clarification!

First time I did it I wasn't happy with the result so I removed it with paint stripper. Came off very easily so I don't think without baking its properly hardened.

I can confirm I used this Simonez engine enamel for my DT175MX.

I painted it gloss black last year and its doing fine: whilst 2 strokes get hot and i'm sure helped to harden it, The cylinder obviously gets hot but the gearbox doesn't get that hot at all.
I sprayed the whole lot and whilst it may have lost some of its initial sheen . it looks more like factory finish now than it did when i first applied it (Yams were satin)
i didn't want to use the Matt which is rated at 300c on the can.

Nonetheless, mine has turned out just fine, no flaking, I didn't bake it, but i did apply thin coats in FULL sun, not sure when that was as i don't think we've seen the sun much since!!!

I have heard a perfectly acceptable finish can be achieved from using Barbaque paint. BBQ.
In fact over at the yamaha forum its quite rated, although i'd already sprayed mine before i knew it!

I'm currently spraying my 400/4 engine with EHT (extremely high Temperture paint, not VHT)
Not used it before but it seems to cover well.
20yrs ago I used Eastwoods engine paint (no longer availble, I checked with Eastwoods USA)
That was the dogs danglies and looked as if it had only been applied recently not 20 years,In fact it looked good right up to taking it off the road last month for an engine overhaul.

NE0:
Incidently, 120c is bloody hot! 20 degrees higher than boiling water!

Engines get hot, yes but when it rains, if the engine was well over 100c then rain would boil as it hits the cylinder head and engine, steam would be generated continually.....but it doesn't.

A stationary engine will get hotter yes but the engine is air cooled,...engine paint rated at 120c is fine for an engine but NOT exhausts.

120 degrees sounds like IT shouldn't be ok, but manufacturers do a lot of research and if it wasn't any good for engines they wouldn't sell it.
