1980 Fleetside Silverado is rusting under the bedside molding/trim where the stickers attached to the truck. See attached pic.

I love the look but I hate the idea of re-attaching the molding/trim in the same way after repairing the damage. I vaguely recall someone on here mentioning he uses magnets to mount the molding/trim so that he can periodically remove to clean underneath, but I can't seem to find the post. I like the idea and I couldn't care less about resale or winning contests.

Is anyone using magnets or some other alternative to stickers?

Has anyone given up on the molding/trim and gone with a clean look instead?

Many thanks,
D.

I'll only keep two tone trim. That's usually easier to clean out. But the truck would have to be really nice. Otherwise I pull the crap off.

@PrairieDrifter thanks for the quick reply, though I'm not quite sure what you mean by two tone trim.

On a related note, here's another alternative using paint that just grabbed my attention...https://www.youtube.com/watch?v=unNt_-lC-5A&list=TLPQMDcxMTIwMjMehPexAD0Gqw&index=1

Two tone trim is a 70's thing.

Your other options are real pinstripes, or adhesive vinyl stripe. I pulled the stick on door bumper crap off my 84.

Yep--my 1980 has the same two tone trim and it all looks to be attached with the factory trim clips and adhesive.

I'm leaning towards replacing with magnets or real pinstripes. Here's Part 2 of Dirty Dan's pinstripe masterpiece...https://www.youtube.com/watch?v=FofSG7Q0zJM

Magnets are good for a lot of things, but sliding inertia is not one of them. With road vibrations and jolts I'm sure you would be readjusting/losing pieces/ scratching paint. Or if a twig or something catches them.

3M double stick tape (not a sponsor) works as a single use solution and can be removed with acetone or lacquer thinner.

Going off of that picture, you are barking up the wrong tree. That looks to me a fault of improper paint prep. What probably happened was the paint/primer did not adhere well, the double side tape pulled the paint off, then the rust formed over time.

Double side tape is the ideal method for attaching light weight body trim, to prevent rust. It's the reason why (well, one of them anyway) manufacturers switched to that method, rather than screws or clips that go into holes in the body.

That makes sense. The PO repainted the bedsides and my detailer opened my eyes to just how lousy the paint job was. So I wouldn't be surprised if the stickers lifted the paint. Though I only posted one pic, the damage is under nearly every sticker on that bedside molding. Many thanks for the helpful observation!

Yep, if they are all like that, my diagnosis is still the same. It's just poor prep work, unfortunately.

I’m still considering doing the same. Part of my deliberation is whether to replace the molding with striping along the color changes. What did you do?

If you’re going to spot repair the rusty areas I think the original metal trim will hide that better. And IMO looks better.
If you do end up going with a wide pinstripe (like 80s trucks) know that the paint has to be smooth underneath or it will telegraph through. I spent a lot of time sanding down a clear coat edge and can still see it in spots.

Hopefully a little info to help your decision.

UPDATE: With all the solid advice above, I've decided to launch into a DIY spot repair project that will include reinstalling the original trim as it was originally installed with stickers and three screws. Will post details of the repair in a separate thread for all posterior. Thanks again for the help!
