Hi guys,
I apologise for the newb question but I want to have a go at stripping and respraying my brake calipers and maybe the cylinder head!!
I’ve found lots of advice on here regarding type of paints etc but I need advice on the prep work.
I was going to strip them with either paint stripper or brass? wire brushes, wet and dry sandpaper etc. Does the surface need to be rough to key to the paint or do I just sand smooth then use primer. I’m concerned about removing too much metal 😬!!!
I’ve tried you tube but there’s so much dodgy advice on there!!!
If anyone could direct me to a good tutorial that’s suitable for bike parts that would be great.
Cheers
Jim

In an ideal world get them vapour blasted

Hi Steve,
So vapour blasting would be the ideal way to clean them before painting. I presume I’d need to remove the paint before getting them vapour blasted. Then use a primer?
If I didn’t go down the vapour blasting route would a wire brush/wet and dry be the correct way to do it?
Cheers
Jim

Vapour blasting will remove the paint and everything else
Some paints go straight onto bare metal
I’d still rough them up a bit with sand paper before painting though

I etch primed mine first then used a satin rattle can, Simonize I think. Degrease with thinners again and again after stripping paint with some proper paint stripper (Possibly stocked by a friendly car paint supplier?)

Cheers Jim If you don't have the vapour option then yes clean with brake cleaner, wire brush/sand then paint as per whatever paint instructions you use I've used the VHT paints before and the primer does help adhesion Caliper paint can be a bugger to get off but if it's solid and you aren't blasting then just sand smooth Steve |

You missed out " explain to wife/partner why the dinner tastes of paint and the kitchen smells like a paint booth " 😂 |

That’s great. Thanks for all the info guys 👍
I think I’ll have a go with one of the calipers and see how I get on. If I make a pigs ear of it I can always take them to someone who knows what they’re doing!!!

Cheers matey.
Last question. I promise 😬. I was going to get some sanding pads to clean up the caliper after paint stripping. What grit would you recommend for paint removal and finishing off just before painting. The pads I’ve looked at are 80 and 120 grit?
Cheers
Jim

I usually buy a pack with various grades, so I have a selection.
