Okay, anything special we need to know about powder coating removal?
I have spoken to a local firm who do media blasting, who quote £50 an hour + vat for their services. I mentioned that the frame was powder coated and there was much sucking of teeth and they said that however long it takes that would be the cost.
So since powder coating is quite hard, can we soften it up or use a chemical stripper?
Anyone with any experience?
Cheers

Hi Steve,you can use paint stripper very carefully,you can also take it to a paint stripper specialist who will dip it in a bath till clean,moderate cost,or you can rub it back and re powder coat,cheers Nev from OZ

Try brake fluid!
I used an orbital sander on the thin walled exhaust headers before I painted them with no ill effects. Just be gentle and let the tool do the work.

Gawk! I despise sanding round tubing. Oh, the horror. >:(

Mine or the bike's? ::)

I have to say that we are not looking at spending the foreseeable future trying to sanding it all off.
We were hoping that there was a procedure for removal, at reasonable cost and reasonable effort.
Tony is not going to be happy :-/
I will have to try some paint stripper, it used to work.
But I am no longer sure it has the 'guts' any more - the European 'Socialist B**st**ds' Union keep trying to save us from ourselves by removing all the active ingredients from this sort of thing.

Powder coating is just basically a plastic coating. The powder is applied and the "baking" process melts it. Unless it's all chipped up maybe just scuff and use it as a good durable, well adhered, base for your next color?
-
Justin,
unfortunately, the powder coating is cracked and would not be a good base for further painting. It has to come off.
On the bright side, I tried some modern Nitromors paint stripper last night and even the modern rubbish stuff does soften it enough to stand a chance of scraping the majority off. But it is going to be messy. We should be able to get most of it off, and the residue can then be blasted.
Let you know how we get on.
Cheers

I agree with LUCA, just try a little brake fluid and see if it works better than what you are doing now.All in all it sounds like a bit of messy work ahead of you and Tony. Dave2

You need an airhead apprentice that is in dire need of some cash for his next date with his girlfriend. Its a rite of passage, the messiest job is for the novice.

Good point, Victor!

Planning a driveshaft and final drive oil change. I do hate that sticky gear lube so I'm thinking... ;)

I meant to mention a helpful little technique when using paint strippers.
If using the jelly type, you can sop it up with rag and wrap it that around parts of the frame. Help hold the stripper to the underside and also helps to keep it from drying out, allowing more time for the chemicals to work.
If it's a spray type you might be able to keep it in with some plastic wrap, provided it doesn't melt away.
-
Fortunately we are heading into winter, and currently are barely getting above 10 degrees Celsius. So the paint stripper is likely to get half a chance to soften the powder coating.
Also I would rather that that is all it does, as if it gets all slimy, its going to be very messy. I want to able able to scrape it off with a triangular ended paint scraper, rather than wipe it off with a rag.
What we will attempt to do, is to get the vast majority off, then take the frame, sub frame, battery tray and swing are to be blasted.
cheers

Just wondering - A heat gun might soften the powder coat enough so you could lift/peel it off and then use the paint stripper fro final cleaning up
-
Tony the heat gun may assist, I will give it a go........."Steve can I borrow you new heat gun"?
I usually use the Mrs's hairdryer for heat shrink and the like but I she'd be awfully Pixxed if I used her new one after what I did to the last one! :-X
-
I bought a "throwaway" car (Hyundai Getz) recently to drive to and from work, the car had previously been used commercially and came complete with an incredible number of vinyl letter stickers on it. The North Queensland sun had attacked the stickers such that it was impossible to just peel them off. I found that my heat gun waved in their general direction for a few seconds made removal an absolute snap.
Then I got careless and waved the heat gun just a little too long on the painted plastic bumper bar. A section of paint about 4" in diameter leapt off the bar and curled itself up on the floor and there is a pronounced indent in the bar.
So I sort of know what you mean.

Monte: Having your own groupie makes it oficial. You now unequivocally an AIRHEAD GURU.
Well deserved

Now, Victor. Thinking you're a wee bit over the top here. Anyway...
I really may need to rethink letting "new friend" near my motorcycles should his tool skills be similar to his riding skill. Took a Sunday ride with him -plus another relatively new rider- and both gents were basically "unsafe at any speed".
After watching him wobble along at 35-40 mph on a 60 mph Texas Farm-Market Road, with me riding drag and pulling a long train of very impatient pickups and cars, we traveled an entire 20 miles in just under One Hour!
I was sufficiently concerned for my own safety that, with apologies, I left 'em both at a small crossroads store. It took me 20 minutes from 'farewell' to my home covering the same mileage.

Been there!
Sold a bike to an old school friend who had recently got into biking. I managed 2 rides with him before I had to give up. Not that I am a speedster or anything, but wobbling round the corners, losing all his speed at every bend, was more than I could handle.
The second ride, he invited someone with an ancient and very decrepit Sunbeam. I had to leave them and meet them at the destination - a pub. I needed to be at least close to the speed limit.
Still, he is apparently better now.
We all got to start somewhere!

With your "credibility" you should suggest they take the MSF course. "For insurance purposes" or "as a tune up".
Think of the bikes man! What if they go pavement surfing?!
-
Monte: A very very good older friend of mine answered one of my ranching question with: I could answer you but you wouldn't understand. But go and take this course with this person and then we can talk.
Matt's right, let someone who is paid to have the patience to train him do their job.
-
Thanks, gents.
I did ask the man if he had taken the MSF course but never really got a straight answer. I don't even know if he has the MC endorsement on his license.
I plan to make contact with him, again offer the MSF ideas, and will see what transpires.
Later...

Funny you say that !
When I ride with friends I make a point to be the last one and the slowest.
I abide to the speed limits and never start first on a green light (in France, we are quite requested to split lanes and stay on first line at a traffic lane).
It is funny because sometimes I rode a road I know perfectly waaaaay slower when in a herd as I did alone.
I'm far from a good bike rider but I plan to ride for as long as I can ;-)

I hear it said that you should "ride your own ride" so that you are not being caught up in another rider's pace which is outside of your comfort and skill zone. Dave 2
