Once again bikeforums has been super helpful but this time with disappointing news that Velocals will be no longer be producing bike decals. Good to know so we can get our orders in.
But which type do you guys recommend? I was going to order the standard 2 mil type but they have UV laminates in either high gloss, low gloss and matt. The one I need is for Columbus Spirit tubing which promptly disintegrated on a NOS frame. They claim that the UV treatment will make the decal last twice as long.

It comes down to your intentions. The uncovered ones are for full restoration assuming you are going to clear coat on top of your decals.

frankly, I love the look of patina, new decals and a clear coat to stop any further rust.

Good question. I plan to remove the remains of the existing decal and place a new one in its place. It will not be under a clear coat.
Should I therefore splurge on the UV coating?

Biketiger-

Yes, since there will be no clear coat, get the UV resistant ones.

Got it - thanks for the advice!

I've done the 2 mil adhesive decals a lot with them. Just did the 1 mil for my latest bike. There is still an edge, but either thickness applies well. For either, I'd go with a glossy finish as it matches the glossy paint of most lugged bikes unless you want the matte look. Waterslide would be good, especially for running clear coat over. I am ignorant as to a waterslide's durability without a clear coat, so feel free to educate me on that given your experience (those of you who have done so)

In my case, the Columbus Spirit is a large decal at the bottom of the seat tube so I am not too concerned about the edges as much as longevity. Since Velocals claims the laminated ones last twice as long and I will be applying over a clear coat that's what I'll do.

would clear coat before and after decal application eliminate the edge?
