Stripping / Painting / Coating / Cleaning Rims

If i want to paint a seat post that is anodised, do i need to remove the anodising or just paint over the top with primer, i assume there is no need to remove the anodising but just want to check

PS - avoid the jokes of needing multiple cans to paint my seatpost

if you spray any seatpost, although you will only use a very small ammount, the overall width will increase slightly, therefore if your seatpost is a fairly tight fit in the frame, it a) either might not fit or be too tight, or b) you might scratch the crap out of your newly painted post [ooh.. er] when fitting.

yep realised that, so i will scratch the bottom of it, but it's not going to be moved once it is installed

Dear Mr Tynan sir,

I want to spray paint a frame I got for free (I don't think it is worth the Armourtex treatment). Can I follow your instructions for this job, too? Will it work?

Yes.

You will need multiple cans of spray paint to paint your seat post, in fact it might be like the forth bridge which is so long that as one team finish painting at one end a second team have already started to re-paint the other end as it take them so long.

Anodized surfaces are very hard and flat, you will need to key the surface a little so as to allow the paint to mechanically stick to the surface. Otherwise the paint will flake very easily.

Just mask the post with masking tape at the insertion point. And remove the masking tape after you have sprayed the post - but not before it is dry - other wise removing the tape will pull off bit of paint with it and give you a crappy edge.

especially when it got people saying "dear mr tynan sir" to you instead of "oi prick!".

They still call me that in real life, the few crumbs of respect I attract are all on the internet.

Hi everyone, I'm new here too, trying to get my post count up and ask sensible questions at the same time!!! Just wondered if anyone has found a decent candy paint in a rattle can?

fr fr fr fried chicken is the illest!!!!

im spraying my frame soon just need best advise on stripping the paint, i usually use sandpaper but takes a while to rough it up....is it best to strip down to orginal metal or not??
tynan seems like the person to be aiming this at

Good god, I have another job now, the Claire Rayner of spray paint. :)

I am evil, so therefore I would use Nitromors, but if you are going to use sandpaper just take it down to the undercoat, that stuff is stuck on the bike very very well and you will get a better result if you work on top of their undercoat/primer.

No need to go down to the metal.

lol cheers man

I'd strip to metal so you can match the undercoat/colour manufacturers (although is going to be a longer/more expensive process), for the best finish use loads of thin coats with as much drying time between as you can bare..?

I think you need to apply the colour within a certain period so that you form a chemical bond (and not just an mechanical bond) - let it dry too much and you will not get that chemical bond, you would have to check with each manufacturer (ie: read the can) but they often recommend leaving just 15-30 minutes between each coat so that you don't plie the layers on while still wet (which can cause runs and pooling) but so that the previous layers becomes tacky but not dry.

I agree about going to the metal if you want to do a 'professional' job, in that case I would simply Nitromors the frame and not sandpaper it, but I still think that for most home spray jobs using the base already there is better as it is likely very well bonded to the frame.

Heh, good thread that is.. Iam going to spray my silver spokes on ready built wheels + braking surface on rear one i think.. gotta do a lot of masking i guess :D

I have a yellow velocity deep v and would like to remove the paint, However I have black spokes and I am worried if I use nitromoors the colour of the spoke will be affected as well? I have see somewhere that sandpaper could be use to remove the paint? Any other methods I could use (Besides taking the wheel apart)? Cheers

If you want a the best result with not too much effort just take the wheel apart use nitromors and then rebuild it. Are you going to repaint the wheel a different colour or just keep it raw? If you are repainting it will probably be alright to just rough the surface up a bit with some wet and dry and then paint over the top.

utfs! :)

Are the spokes anodised or painted?
Use Nitromors carefully with a paint brush around the spoke holes.
Either way you do it is going to be bloody boring and time consuming if you don't unlace the wheel.

You definitely need to dismantle the wheel - you would be heading for a total fuck up if you attempted this with the wheel built.

Ok cheers guys!
