Hi Guys,

I clearcoated my motorcycle petrol tank & had a couple of bubbles caused by the pinstripe tape not stuck properly. What will I have to do to solve this ?. Can I carry out a local repair where the bubbles are or will it mean flatting the whole tank & clearcoating again ?

Many Thanks

Mick

Sorry thought Id posted a pic !!!

Here you go. The gold pinstriping has also slightly bubbled in places caused by a small "ridge" that formed when I did the white over the blue. Any tips on avoiding this ?.

They say you do learn from your mistakes !! :blush:

Thanks again

Mick

That's not coming out; more clear is not going to make that problem magically disappear. Solvent creep affects the adhesive and causes the edge to pucker. You also can't put decals over a taped hard edge and expect it not to show; the surface must be flat. To prevent vinyl lift, avoid wet coats and allow maximum flash. Best way to avoid it is to use paint throughout, forget about vinyl stripes. Here's a thread with the same issue. www.refinishnetwork.com/component/kunena...inish/27166-graphics

Painting over any decal is risky. I have done it,and be ok..then next time, have a problem like yours. Not being able to sand the stripe ir decal is part of the problem.

Thanks Scott,

Can you give me any advice on how to achieve a 2 tone job with sharp lines & without a hard edge ?. Which tape to use etc ?. I did actually use line marking tape but was still left with a slightly raised edge

Many thanks

Mick

Mick, start with a primeed. Tank. Cover the area you don't want painted.....that would be the larger color. I always paint the smallest area color first. Paint it with base. After it dries, you remove the tape, there will be an edge,scotch pad that off and now tape the color you painted. The new color will match edge to edge. You just have to tape it tight. Another way is to clear over the first color. Scuff the whole tank, paint the second color and then reclear the whole thing. If you have a little edge you can resend and reclear again. Anybody else? I knw it is a lot of reclear..... But that's what makes it slick. Bill

Wrong. You never tape graphics edge to edge. You also don't use a scotchbrite on basecoats. That's not going to be very good for metallics unless you want that custom brushed finish. Multiple colors can be done in one day observing adequate flashtimes. If not, blow on clear base and proceed as your abilities allow. Custom painting has different approaches depending on the complexity of the artwork. Shoot 2-3 coats of clear over finished artwork, sand and clear again to level the surface.

Thanks for your input guys. I'm a beginner doing my own stuff & some of the terminology is confusing. I found this thread, www.refinishnetwork.com/car-painting-how...how-to-paint-stripes on painting stripes. It recommends clearcoating the hard edge then wet sanding & clearcoating again. Would it be also be feasible to sand the hard edge separating 2 colours a little before the first clearcoat ?.

Thanks again

Mick

You can't sand metallic base at all right before clearing. It will mess the flake effect up. On solid colors you could but I wouldn't. Just clear , sand, and clear again.
