I have sanded exhausts and spprayed with BBQ satin black heatpaint, but after 8 hours its still tacky?!
I have read that to cure the paint you need to heat up the BBQ afterwards!!
difficult with exhausts off bike!!
I know members have used this paint.. advice please!!

BBQ plasticoat paint must be cured within 3 hours of application. I did this by leaving a hot air gun pushed in the end of the exhaust and left on for an hour, switching either ends half way through.

What i do is poer boiling water over the pipe then dry of with a towl hang on the line and spray . The heat from the water evaporates anything left on the pipe after a wipe down and after a spray they are dry with in an hour. But after they are fitted and the bike is started up they will go of any way /.

Heat the exhaust with a plumers blow torch and apply the paint then when dry bake on with the plumers blow torch ;D if you use this method be careful you do not burn your shed /garage down  |

Golden rule I found with this stuff is to not put on too many coats. To thick a covering you get bubbles when heated on the bike, which then starts to peel which you then have to cut back and respray which creates patches which then you have to apply thicker to cover  .............. found out the hard way....but great if you do it correctly as it says on the tin  |

I have the joys of painting lorry body repairs in the freezing cold occasionally, to get primers to cure we use a hot air gun to heat the body, spray the paint and use the hot air gun in conjunction, sort of spraying both if you know what I mean, works a treat!
As bossy said, thin coat, wait until it's dry then reapply, build up the coating, don't try to do it all in one coat.

Platikote looks good, did mine with it . My headers were in a state so I used a wire wheel on a drill to remove anything remotley loose - I wen over the whole exh. to to provide a good key.
The Platikote paint is supposed to be cured within or a few hours so I hung the exhaust from some wire and shoved a hot air gun in the inlet and left it there for an hour or so on each
BEWARE IF YOU DO THINS THEY NEED TO BE DECOKED FIRST
If you don't you'll have a garage full of smoke, red hot exhausts an probabaly a fire!
(I decoked mine before I painted them, using the same hot air gun - outside)

I tried all the BBQ paints and nothing was durable enough. I found it scratched really easy and was too easy to rub through when polishing the exhausts. So I went for teflon coating  These are the pipes as delivered last night I'm super impressed!    They still need oiling and running up before I can polish them. Simon |

Hey presto, a cooked breakfast on the arrival at your destination! ;D  I asked how durable is it, he said don't let your lass near them with a spatula Oiled 'em up last night, going to put them on the bike and run it up today to bake them then it's good old quality polish. Even before oiling they had a weird slippery finish, it's different to pan stuff though. I'll put more details in a different thread when I've had chance to evaluate it as it's not cheap Simon |

The Plastikote is supposed to be cured with 8 hours of painting (I think). I did mine by hanging them up from lengths of wire from the garage ceiling and shoving a hot air gun down the inlet for an hour. Paint started tacky and finished dry and hard.
WARNING!!!
So not do thins unless you have decoked the exhausts before painting as you will set fire you your garage and burn the paint off. De-cokeing can be done very effectively using the same method (but outside, not in the garage!!)
If the bike's a runner, get em on ASAP and go for a ride.
