You will perhaps wash the bare metal - this will immediately form rust again!
Also if you plan to powder coat then you can't paint. And if you plan to put a 2k process that is you want to clear coat the paint then go in for a 2k base coat instead of using a 1k color and coating it with clear coat - use the correct chemistry between the substrates and top coats to get a lasting durable finish.
Also post the primer you must use the surfacer. Use a porous ppg putty to fill in any dents and then do not apply any degreaser - spray the surfacer.
Also - how does your guy figure out a bend in the fork? If there is a bend of a few mm it wouldn't be visible - does he have a measuring jig? Can you send pics of the measuring jig? To straighten out the only way will be to heat the fork which will take away its structural integrity because you will not be able to anneal / temper the fork the way it is done in the factory. Recommendation - Dont do it or the damage will be irreversible.
If you need step by step guidance on painting in detail let me know.
Check out my Lambretta restoration thread - you know it!

The garage where I'm getting my repainting is well-known in B'lore, he has done a lot of Bullets and the older motorcycles. Chances are, if you see a Bullet with a good paint/chrome job here, it would most probably have gone through this particular garage! I have already got some chroming done, and the quality is real good.
You have brought up a lot of interesting points, which I will discuss with the garage owner. Great thing is, you can discuss what kind of paintjob you want.
This garage does something called 3 in 1 treatment to remove rust from the bare metal. The acid bath is sufficiently diluted to work only on the rust, and not harm the metal.
Actually, the garage owner has just thrown a few ideas at me, and I need to decide what paint process I want. The garage has all the required resources to do the job.
I'm not sure how possible fork bends are located and fixed. I will enquire about this process. The thing is, my scooter was in a minor accident with the previous owner. This accident resulted in a slightly bent front rim. So I will need to check if the fork was damaged.
I am particular about the fork, as I have first-hand experience of a fork failure on a Lambretta when I was younger. I used my dad's Lambretta when in college, and one day, the fork broke. I had stopped at a traffic light, front wheel in a pothole, and I turned the handlebar slightly. A dull "crack" and the handlebar was rotating freely, but the front wheel was still pointing forward! I still thank God that I was not moving when the fork broke! My mech got a replacement from a junk vehicle. |
