DDK - Die Deutschen Klassiker

Hi,

Wondered if anyone has good experience of the best way to remove powdercoat from a tubular chassis.

The chassis has had some corrective brazing work done, hence the existing powder coat has burnt off in places. I want to get the whole thing stripped now for either painting or re-coating.

Seems like the options are;

Blast - needs aggressive media and I'm worried about pitting the frame
Heat - burn it off followed by gentle media blast, seems expensive and will take weeks
Acid - dip company prefers drain holes in the tubes to ensure acid isn't trapped

Not really keen on any of the options but need to move the project forward. Any sound advice welcome.

Thanks

I've been in a similar position on some motorcycle parts.
You need a good grit blaster, so having used them 4 times now I suggest you contact Redditch Grit Blasting for advice, obviously based in Redditch so not too far.

Maybe go the whole hog, blast clean and then have them re-coat?

Not expensive, but they really are good.

Angie grinder wire wheel?

I’d imagine any powder coat place that could cope with a full chassis would be able to blast it as well. Maybe ask for a joint quote?

Angle grinder wire brush would work but would be pretty low on the fun factor

.

I've used Protech Coatings in Wolverhampton many times over the past 10 years to media blast & powder-coat lots of parts.

It might be worth contacting them for advice:

Many thanks for the replies everyone.

You've convinced me blasting is the way to go. I'll appeal to whoever does it to be as gentle as they can. I did consider the wire brush method but it barely makes an impression on the power coat which has adhered very well to the frame and cured really hard too.

Cheers

If I may..
I would certainly get the blaster to paint it after, minimum chance of corrosion forming before paint.
At Redditch the same man does the job, blast and paint, and you can talk to him on delivery so can put your request to him directly.
