Repainting a bike frame?(5 posts)

Repainting a bike frame?Klack
May 28, 2001 3:18 PM
Hi. I have an older Rocky Mountain Hammer. I have completely stripped it of parts and it is now clean. My problem is that I need to find a good paint stripper. my friend recommended oven cleaner (which he used to do his bike). that did not work at all. can anyone recommend a good paint stripper? It is very tough paint, I tried hand sanding a bit but that didn't do a whole lot. Advice on this procedure would be greatly appreciated.
Cheers,
Shaun

I've had my steel bikes repainted before, and I took it to a shop that specializes in stripping paints off delicate metals (aircraft etc). They used crushed walnut shells with a sand blaster, or glass beads if it was more stubborn. The nut shells and glass are denser than the paint, but not as dense as the metal tubes.

I used the nastiest old paint stripper I could find at a paint store to strip mango(yellow) paint off a Cannondale headshock fork. It took awhile and many coats of stripper, steel wool and elbow grease but it worked. That's the cheap route. A shop that does blasting should be able to blast the paint off for a reasonable charge. As Atombomber said, have them use walnut shells or plastic beads, not sand (I would stay away from glass beads, they have essentially the same harness as sand).

DONT USE SAND PAPER!

Only attemp this if your frame is Aluminum. The process will involve water which doesnt mix well with steel. See plan B if your frame is Steel.

Use JASCO Paint & Epoxy Stripper - purchase at least 1 pint. You will also need chemical resistant gloves, cheap brushes, paper mixing cups, plastic scrapers, scotch brite pads (coarse & medium), steel wool, utility sink with running water & a well ventilated work space.

Follow the directions on the can. Dont get the stuff on your skin -IT BURNS! Dont get it on anything else - it will turn it to snot! It will probably take 3-4 applications followed by scrapping with plastic scrapers and scrubbing with scotch brite pads. Final clean up with steel wool or a dremel with a brass wire wheel.

All of this will take you about 12-20 hours and cost about $40.

Plan B:
Pick up the phone book and call your local powder coater. Tell them you need the frame stripped (bead blasted) and repainted. Should be around $100 for basic finish, 200+ for pearl, metallic, etc.

JPA is right in that bead blasting is the way to strip it (should cost around $25) and then having it powder coated (around $100). I have a steel Rhygin Juke I had this done to a couple of years ago by a local guy who does Harley Davidson parts and lawn furniture and it worked out well. Just tell them to pay extra attention to the bottom bracket threads and the cable stops. He also did an aluminum Pro Flex frame for a buddy and it worked out great.

You can probably contact Rocky Mountain and get a new sticker kit for it. If you do that, make sure you put some kind of clear coat on it or the stickers will come off again.

Good Luck.
