Is there a fix for bad side molding?
I know this is an age old problem GM is infamous for. But have any of ya'll experimented with different methods of aplying it, that didn't make it fall off later my current Truck has sheet metal screws driven into it by the previous owner. When I get it repainted.one, I'd like to avoid that method. What's funny is GM still has this problem today. My friend bought a 2010 silverado high countRyder brand new. The molding on that truck falls off, if you look at it wrong. Input would be appreciated, thanks.

Re: Is there a fix for bad side molding?
you need to make sure the surface youre applying to is clean and if itzs glossy reduce that gloss some so the glue stays stuck

Re: Is there a fix for bad side molding?
You have to use an adhesive prep (solvent) and you have to apply pressure to "wet out" the adhesive. You can't skip these steps, especially the adhesion promoter.
In the assembly plant it is enough to deflect the door sheetmetal, so you have to press pretty hard. I used a rolling pin that I borrowed from my wife. It's been almost seven years and my moldings are still stuck on. K

Re: Is there a fix for bad side molding?
You are right, though: when we first came out with these adhesive moldings I remember seeing them stuck to the pavement and the guard rails all along I-69 and I-75 in Flint.
Quote:
Sounds like the plant screwed up his specific truck. If you peel the backing too soon (if the molding sits overnight, or during a shutdown like changeover or a strike) then it gets dirty and won't stick. They also pre-heat the moldings so they are more pliable. If the operator grabs one right out of the box and skips the preheat then that could be a problem too. K

Re: Is there a fix for bad side molding?
Thanks, I guess I'll have to be careful putting it on there. But you're right, sometimes workers do a better job at intlstallation because the molding on my friends 04, he bought 10 years ago hasn't moved an inch.

Re: Is there a fix for bad side molding?
Not a week goes by that I don't have a customer come in with a molding falling off. Regardless of GM, Ford, Honda etc etc, they all have issues. It is because there is far too great of a risk when dealing with a molding held on with double back tape. Heaven forbid real clips be used, or a screw hidden by a push in strip.
Sometimes we can clean and retape but most of the time the owner has gone long enough that the molding is too distorted or actually bent/broken and has to be replaced. Anytime we replace a factory molding with the factory adhesive tape, we add more to it. If we ever had the opportunity to have some engineers in a room alone, I promise you there would be bloodshed. ![]()

Re: Is there a fix for bad side molding?
I am removing all of the molding and emblems and having the body shop fill all of the holes prior to repaint. Youngsters around here seem to order their new trucks without molding (base models) and remove decals from the body for a clean look. Of course, then install 20s, slam to the ground, etc.

Re: Is there a fix for bad side molding?
The quality of body side molding is not sufficient to stand up to 115+ degree heat in HotZona. Silver plastic chrome covering on stock molding discolors and flakes off quickly. Solid black holds up better but fades quickly and needs constant UV protection. I plan to park away from other cars to avoid door dings as I did with all new vehicles I purchased.
I don't go for slammed trucks or oversized wheels either, but I am now a fan of the clean look for reasons mentioned above. My neighbor has a 70s vintage square with no trim and a fresh white paint job and it looks good to me (must have been a base model.) His truck has no hub caps, but I think with dog dish caps and beauty rings it would look a lot better. |

Re: Is there a fix for bad side molding?
My truck is a Silverado also, but I am not a purist. Side trim has just been a PITA with this truck ever since I have owned it (past 14 years) and I don't want to deal with it anymore. All of the emblems and trim fell off. Adding the dump conversion to the bed ruined any original preservation possibility.

Re: Is there a fix for bad side molding?
I don't think trim screws look all that bad to me, either chrome or black. If the trim has a black strip they are very hard to see, especially if these aren't show trucks.

Re: Is there a fix for bad side molding?
Pop rivets. Lol. The PO used some rusty screws, so the holes were already there. Just used some 1/8 rivets and its not going to fall off. Not really noticeable if you paint them black.
