Removing powder coat

Hi lads,

 

Does anyone know the best way to remove powdercoat from cam covers and rattle can paint from stock intake manifold?

 

Need them as smooth as possible ready for spraying again.

 

Also does anyone know how to smooth off a precision turbo for paint? To remove those tiny little bumps?

 

 

As there is so many different types of blasting I don’t know which is best/safest for the parts

 

Thanks

Lewis

Walnut shell to remove old powdercoating and aqua blasting to remove paint would be my choice. If it is casting marks you want removing get the Dremel out.

If blasting the cam covers you MUST remove the baffles and clean them out properly before fitting them back on the engine.

Find a powder coaters that does chemical stripping or a chemical stripping comp, should be very cheap

to do just cam covers, one in B'ham charged under £10 per wheel as a guide

 

Phosphoric acid is what we used to use at Ibrars before he subbed the job out to

a chemical stripping company in B'ham

 

Works very well and the acid is neutralised in water

Okay thanks for that, would I then need to have it aqua blasted after being stripped?
