I am refurbing a set of front brake calipers, I have stripped them down to thier component parts and am now trying to blast the carrier/caliper body with my own DIY blast cabinet/compressor. However My blasting setup isnt powerfull enough to remove the original paint/powder coat. Its cleaned the non coated surfaces well, and all the surraces are now clean and smooth albeit still coated. My plan is to give them a good coating of etch primer then a few coats of hi-temp colour, and then a few of hi temp gloss laquer. My concerns are,should I use, if its available a hight temp etch primer and will the original coating cause me any issues. Obviously I could take it to a proffessional, but initially id like to have a go at doing it all myself. Any advice would be most welcome.

From experience I think the biggest problem you could end up with is poor quality seals for the pistons. I've had that and before I'd take the risk I decided to buy new calipers.

The seals/rubbers are in a kit from a company called Biggred, a well known caliper remanufacturer, I have used them before without issue.

Bigg Red are good, very good, and I use them for any overhauls that I need to do on cars with tricky-to-source calipers.
However, to be frank, they are so good, it's almost not worth overhauling any calipers myself now - even on my own cars. When you look at their workmanship and quality of finish on the returned calipers, the extra £40 to get a caliper overhauled by them is trivial. The finish seems to last a longer time than anything I can apply, and you have a choice of several finishes (cheap to expensive).
The best thing about having the caliper overhauled by Bigg tred is that they do this job day-in, day-out. It's all tested, and the chances of subsequent failure are slim indeed. Not a bad thing on a safety-critical hydraulic component?

and if the short straw did happen and god forbid it, a serious fatality did occur, the final straw does not drop on your lap, it goes straight back to the re-conditioners. There is a lot to be said nowadays for passing the parcel.
