My GT cost me my Alfa...how do I lacquer a titanium frame?

My GT Edge has cost me in many ways. It is a posh titanium frame, and cost me a lot of money; the previous owner had given it an expensive paint-job, and it took eight hours for me callously strip it; I had to drive from Hull to Northampton to get to a specialist motorsports works that did an excellent job of glass-bead blasting it to make it look pretty, which took all day and cost a fair bit in fuel.

Unfortunately, this also cost me the other love of my life. Thirty miles left of a 200+ mile round-trip and I turned the stereo off because I was thinking: is that the road surface making that noise? The usual rasp from the Supersprint exhaust fitted to my immaculate Alfa 145 Cloverleaf sounded (and felt) all wrong. I wound down the window to see if I could hear anything untoward, but instead was greeted by a terrible smell of burning oil. I was next alerted to problems when the speedo decided I was standing still and the rev counter went bezerk, followed by a forced outing into the hard shoulder when the engine died.

Things take a turn for the worse at this point: the cabin filled with smoke, and when I got out of the car it was apparent that it was already ablaze. A call to the emergency services summoned two fire engines, the rozzers and the highways agency. I got to sit in a lot of emergency vehicles and the roadsigns lit up slowing everyone to fifty.

The insurance assessor would later send me a report detailing the components that would need replacing. This list included diverse items such as: bumper (it had vanished completely). Headlights (these had also vanished completely). Gearbox. Interior. Engine. Bodyshell. Wings. Wheels. Radiator. Windscreen. Airbags. Paint. And so on.

Which brings me to the titanium GT frame that I rescued from the car before bravely running away: the finish is very nice, but also very receptive to scratches. I know that titanium won't oxidise in the air, but will cheerfully react with anything I bolt to the frame, doubtless egged on by salt from the road and the tip of my nose. I would like to clear coat the frame. However, I took it to a decent paint shop that gave it a try, but their lacquer simply fell off. I called Bob Jackson, but they immediately said no in their own inimitable style.

Does anyone have any experience of clear-coating a titanium frame? Can anyone recommend anywhere? The closer to Hull the better, as I am no longer mobile, obviously. Clear powder coat maybe?
 
Wow sorry to hear about all the trouble you've had. Personally I don't think that clear coating titanium is something you want to do. I doubt it will stay on as you've experienced already. I had a GT Edge Ti road frame that had been painted in DuPont Imron in a Porsche silver color. I chemically stripped the frame and was able to make it look great with a light rub down with scotch brite pads and haven;t eve had an issue with it. Sounds to me like your blasting almost left the surface in a suede like finish rather than lightly bead blasted. It shouldn't scratch or show scratches that easily.
 
I have shed a tear for you.

No bike, titanium or not, compares to an immaculate Alfa :(
 
Sorry to hear about the Alfa. I had a similar problem with my much missed 75, they do burn well :roll:

Hey Kevin, I'm still waiting for pics of your Edge and your son's bike!

The finish on the bike is gorgeous but it already has some scratches (as predicted by the guys that did the work to it) and fingerprints are left on it really easily. Well, every time I touch it you can tell. I know what you mean about clear-coating, but I still have reservations about bare-metal (especially in the British climate!).

I also had a bit of a look at the Litespeeds at my LBS the other day and they are clear-coated - looked fairly thick too, more like a clear powder coat.
 
Pickle, Chris: thank you.

I managed to get a few pictures of the car and even have a before-and-after taken less than three hours apart! I will upload them later. I can concur, the car burned very well indeed. There was a worrying pile of matter underneath the engine bay after they moved the car that had spark plugs in it! Highways Agency said they planned to bill for the repairs to the road, then assured me they weren't joking either.
 
Bad luck on the motor mate. Guess it's time was up, at least it went out doing something worthtwhile, just imagine the futility of it lighting up on the way to the chippy....

As for laquering the frame as far as I know nobody does this to ti. Never seen any corrode in the ways you mention either.

I 1000% agree with you on this. I think it was a spectacular way to go: it was young and never gave any indication of any mechanical problems until it burst out in flames and consumed itself with no warning. Very, very satisfying. Total contrast to my last Alfa. we parted company when someone drove it off for its engine and interior after a comprehensive, three-page MOT fail.

I had no intention of clear-coating the frame until I got it back and noticed how much it hated being handled, and given the trouble I had getting it looking pretty...
 
Coarse bead blasting will give a surface that is suceptable to finger prints which is why most ti companies either brush or polish with some us g gentle poly bead or walnut shell blasting. If I was you I would get some scotchbrite pads and brush it or get some metal polish and take the edge off the coarse bead blasting.

As far as I know no big ti Manu lacquers their frames and I own and have owned a number including litespeed, merlin, seven, fat chance. The only ones I have ever seen were real budget ones. Are you sure you weren't looking at painted litespeed?

The finish isn't coarse - it was glass bead blasted in water and looks very nice indeed, designed to look satin. Its not what I intended originally - the previous owner had painted it, and grit blasted it first. Although it looked great after all the scotchbrite and elbow-grease, the bike looked dreadful in the daylight - the pits looked black, almost like it had been splattered in paint. After the amount of energy I spent getting the finish perfect, the thought of running scotchbrite on it horrifies me! The deeper pits will become visible again. I was after clear-coating it to preserve it as it is ideally.

I'm pretty certain about the Litespeed - I went in there specifically to look at the finish. I'll check which model it was next time I go in there pretending to buy it...I am thinking of spunking the insurance payout for the car on that particular Litespeed...
