89 Timberline re-imagined

GT Fan
Knowing that I like 'fiddling around with old bikes' I occasionally have friends and family say, oh I have an old bike in my garage/shed, do you want it? Normally it is something that I wouldn't be interested in, but very, very occasionally, something interesting turns up. In this case my friend, we'll call him Jim, cos that's his name, told me he had salvaged something from a relative who he helped clean out the garage.

Imagine my surprise when he presented me with the frame, forks and stem of a rusty old 1989 GT Timberline. I was quite excited, but it was pretty rusty, especially the forks. So I treated all the rust to stop it getting worse and then stashed it in my shed, for about 2 years.

It didn't really feature in any plans. It is not exotic in any way, although it does have lovely chain stay Ubrake bosses!! and it is a women's frame. So it kinda just sat there.

Fast forward to this summer and I wanted to try out a new painting technique using Montana Crackle Effect Paint. This Timberline was blue, but there was also the option to get a black and silver one back in the day. I've always like the early 90's paint jobs, so wanted to see if I could recreate it. But Red with Black Crackle, which I thought would look nice with the yellow and orange decals.

Treating the rust previously meant that the existing paint job was poor anyway, so this project was born.

After a rub down and primer I sprayed it with Montana Gold Red:

Then added Montana black Crackle paint. First time using this, a few test sprays showed that the more you spray, the more it crackles. There's a little delay between the paint landing and the crackle developing...It's quite fascinating to watch....

Then decals and clear coat (2K SprayMax - wear a respirator folks!!)

At some point I also decided to throw a whole bunch of GT parts I had at it. This included some BMX bits - a GT Seatpost, and some GT Mohawk BMX hubs.

Naturally I had to modify these to fit the wider OLD, which was a bit of trial and error. I laced them to some FIR hubs that I bought on here a little while ago. They roll really nicely. I am a little obsessed by Radial lacing on the front wheel...

At this point it looks a bit like one of those safety bikes from the 1880's So I put some tyres on some GT Rubber - which are hard to find at the moment.

I finished it off with some nice XT bits - which clearly would have been a considerable upgrade on it's original spec.

Job done.. It's quite heavy, despite the Ishiwata tubing (13.68kg) in fact it is the heaviest bike I have 😆, but lightness was never the objective.

I expect some will suggest I should have restored it to original....yeah, I've done loads of those, and will do more. This was about having some fun and learning new techniques with paint - I already know what I'd do better next time...for me that's what it's all about. :)
 
Great job, it really does look a factory paint job! Was it rattle can 2k that you used? I’d be keen to know what product you used, and how much / how many coats of the clear coat you did (got a frame at decal level and looking to clear coat ☺️)

Hi @Ride_Revive,

Thanks! It was great fun to restore and build!

The common perception is that you cannot get a great finish with rattle cans, but I'd disagree, a professional job is always best, but I think a great rattle can job is better than a poor job by a pro....and, anyway, I enjoy the process.

All was rattle can:

Primer: Spray.Bike Frame Builder Metal Primer- 2 coats
Base: Montana Gold Red- 2 coats
Crackle: Montana Crackle Traffic Black- 1 coat
Clear Coat : SprayMax 2K Klarlack (Gloss) - 3 coats

Frame Prep is key - I spent ages removing the old paint and getting the base ready. Light sanding between each layer Primer>Base> Crackle - but no sanding of crackle before clear coat.

20 mins between coats with the clear coat.

Hung it out of the way to cure for 2 weeks before building up.

At this point I used to sand the clear coat, and polish. But these days I tend to see if I am happy with the finish. I've used it a lot so tend to avoid overspray or hotspots. But this is something you can always do later if required.

I've tried a number of clear coats and found SprayMax to be the best an most durable so far. It's nasty stuff though, so I always remind everyone to make sure they wear a proper ventilator mask, (not just a paper thing) goggles and gloves. I tend to change/wash my clothes and shower afterwards too.

What frame are you restoring?

Cheers! Phill

Thanks for the detailed reply Phil, very much appreciated. The bike really does look superb! The crackle paint is very reminiscent of a Raleigh outland I had back in the late 90s.

SprayMax was the option I found myself ending up at when I looked into it a month or so ago.

Did you get three coats of the 2k out of one can?

It’s a cannondale beast of the east m800 I’m working on. I actually had it powder coated with a view to clear coat myself, so I could protect the decals I add (I’ve used cans in the past with good results but wanted the best I can get for this project in terms of finish and durability, without taking it to someone else to do it).

Some before and after pics, the yellow paint looks good on the photo but was awful in the flesh. I’ve mocked up the bike to sit an gawp 😂
