Ok history lesson here i used Rust Converter on my Extractors i bought used which were rust and then i used a Flame Proof paint on the Extractors but the rust converter could not take the heat and started flaking off and took the Flame Proof coating with it, now i want to respray them but i have a few questions which are

Should i use the Flame Proof paint again it says allow 7 days to cure does that matter? Because i want to be able to do it in a day

What paint did others use?

Is it easy to take the Extractors off which detaching the exhaust? (eg: does it bolt off the cat easily) and is that all?

Also i wanna clean the side of the head while the Extractors are off what is the best way to do it?

All i done was go over the headers well with sand paper spray em with water then get a rag and clean up with thinners. I painted mine with heat proof paint and put them on stright away and worked well.

I sprayed my brand new pacceys 4480. I used wax & greese remover, brake clean & sprayed them with vht mat black heat proof paint. Left them for 24hrs in the sun. Put them on my engine & they peeled off straight away. I got so p****d off i got them ceramic coated & never looked back.
Not only that they look great but alot less heat in the engine bay aswell.

should have had them beadblasted then paint them. that way there is something for the paint to grip to
