Scooterotica

I had stuff stove enamelled, which was the way to go in the late eighties for coatings. My bike has been stored for a few years in not always ideal conditions I have to admit. The coating on steel parts is on the whole still in sound conditions after almost 25 years.

The alloy parts were a completely different story. The alloy was very corroded and the surface powdery under the coating and as described by others, peeled off in large chunks without much provocation, but as I say it had been there 25 years.

Not all powders are the same, it needs to be an architectural / exterior grade to last on your scoot.

Surfaces should be blasted, then phosphated prior to coating.

ive had 3 full vespa px scoots done the oldest is 5 years old and still looks good and i did the lot for £100 great if on a budget just about to do another will post pics on this thread

£100 each

Bargain. Mines going next week. Frame and panels etc 350-400 is the given estimate

That seems a bit on the steep side just for powder coating. does the price include blasting/stripping as well ? I know the powder coaters Ducksta uses and the £100 is about right for a vespa, a Lambretta might be a couple of quid more.

i will blast myself at mick1s, (he offers a blasting service in york) clean any dust out of frame etc and then powder coat, usualy get it back the next day let frame harden for a week then build, ive had a primer coat then top coat done also just the colour streight on top, with the primer a bit of rubbing down etc needed as its thick.

mine is being blasted too, but shouldnt take long, its all either bare metal with surface rust that brushes off or just some primer to try and prevent too much rust.

1-2 weeks turnaround, theres a lot of parts, so I wasnt that worried about the price, until I read someone else gets it for £100.

I thought powder coat had to be applied to bare metal, not phosphurus treated rust metal.
I did a t5 in powder coat L and N in castleford did it many years ago, it was very good .double the 100 quid price. If your getting that its a bargain I would say.
My original post is questioning the longevity of powder coat. Whilst its a quick easy fix to make scooter parts look presentable with a decent finish I am not so sure I will use it again.
The thought of rust proofing first then powdercoating seems more appealing however.

Powder coat is usually applied to bare metal. To get bare metal it is usually either chemically stripped or blasted. If stripped some of the chemicals can "leach" into the metal. To remove all traces of the chemical the bare metal is usually put in the hot oven prior to powder coating, where it evaporates. If the powder coat is applied without the chemical being removed it can lift the powder coat and rusts from the inside out.......which may have happened in your case.

In general powder coating is more rust inhibitive and harder wearing than a normal paint. After the powder coat is applied and put in an oven the powder coat sinks into all the pores of the bare metal, normal paint when sprayed on does not fill in the pores but forms a skin over them, allowing "weak spots" to occur.

Done properly Powder Coating is a superior finish, not done properly it's waste of money....
