I've refurbed the front calipers on my tin top. Involved a complete strip down, wire brush, degrease, some kurust stuff.
I then did 5 coats of brake caliper paint. Finish looks ok and when cold a week later the paint has cured and is dry to touch and not soft. After a drive with some decent braking, the paint feels a bit tacky, just feel they are going to be a dust magnetic! What have I done wrong or just bad paint.

It was Jenolite caliper paint.
I have the rears to do so if I've done something wrong I want to do it better for the rears.

I note some people laquer as well?

5 coats, paint is to thick.
If the tin recommend 2 coats then apply first coat and follow instructions for second coat.
I have recently done my calipers used high temp engine primer 2 coats 15mins apart allow to dry overnight. Then next day 2 coats of standard rattle can red again with time between coats as recommended on the can. Paint will be soft unless left for another night indoors

surely it should cure in the end though? well it is cured when they are cold. I'll try high temp primer first on the rears.

Yeah 5 coats is 3 coats too many. I only use the Halfords one and never had any issues. You do need to let each coat fully cure overnight.

I know it may seem a stupid reply, but i used a paint kit designed for calipers about 5 years ago, and they still look the same today

its in the garage, so when i go out there tomorrow, i will find it and post a link

Normal paint does not work, ive tried
