- How to strip alloy frame to raw finish and preserve?
- mr plowMember
I’m sure some have done this. I have an old alloy full suspension frame with tired paintwork. What is the best DIY route to do this as its a cheap hobby project.
I’m looking to strip the paintwork without killing bearing locations etc. Trying to achieve a raw finish, not polished and then a way of preserving the raw finish. The bike will get ridden offroad etc.
I’m not a fan of home painting or aftermarket powder dipping as the finishes usually don’t last so going for something a little more organic that I can hopefully keep consistent (although imperfect as raw – if that makes sense).
Many thanks for your help.Posted 2 years agostevenk4563Member
I recently did this to my Mega, got it chemically stripped by a local company for about £35, much easier than DIY, then just left it as is, there are lots of blemishes etc. but I like that. You don’t have to coat it with anything, Aluminium oxidises but not corrosively like steel.
Not my wall before anyone starts…

I’ve had 3 frames ‘rawed’ so far. The first was done (spesh enduro) with nitromors and elbow grease, and the other two (On Ones) were done in the chemical tank at my local powder coaters. Cost was about £10 a frame in the chemical tank for a stripped down (3 part) frame.
The chemically stripped ones did need a fair bit of graft to finish them as they came back dull and discoloured with green and black residue in places.

Didn’t strip it but recently bought a raw intense frame and it only took a little bit off effort and some polish to get it looking decent, seems the ideal finish for mountain bikes!
Didnt want it looking super polished as obviously it would get ruined in 5 minutes but just evened it out a bit to get rid of the patchy oxidisation.

My approach is coat the frame in http://www.screwfix.com/p/no-nonsense-paint-varnish-stripper-500ml/17091#null
Leave it an hour
Coat it again
Leave it an hour
Blast it with a pressure washer.

Just a word of caution, chemical dipping can cause blistering of the aluminium itself. I don’t know how common this is but I have had a high end frame ruined, a knowing friend told me it was something to do with weakness in the aluminium layering process. A costly lesson for me :0(
