Bondo/fiberglass as the right choice

Bondo is never used as a repair...it is for correcting small imperfections prior to paint. Epoxies and short or long strand fiberglass may be used for larger voids or where water proofing is required. Nothing will last over rusted metal...not even a welded patch. But a repair over a rusted area can last for sometime if it is kept totally dry.
According to the manufacture it has many reccommended uses. I agree about it's use over a rusted area.
 
to an extent, i agree that sometimes you gotta do what you gotta do.

but when you're talking about preserving a car? yeah, bondo billy hack job doesn't come into the equation.

you gotta do what you gotta do to get to work the next day. you gotta do what you gotta do to keep rain water from pouring down the windshield and shorting out your dash on your daily.

you absolutely do not "gotta do what you gotta do" when you not only have the money but you have that gat-damn pre formed patch panels sitting in the trunk of the project car.
You leave out the part that a person can do what they want to do. My car is fine and will last a long time. My patch panels are sitting in a different car along with my welder. Watch your BDS .
 
Yes and No. Would I ever say a patch like that has been "Done Properly?" No! But keep in mind that not everybody has a welder. Sometimes we gotta do what we gotta do. So if you are in the hobby, must do everything on a budget and are doing all the work yourself then yes, a patch similar to that can be a workable alternative. Done carefully, hack patch jobs can look good and last quite a while.
What you posted in #27 is a definite NO if the question is was it done properly. That being said, a patch like the one done in #27 could last for many years if done carefully. By carefully I mean scuff all areas with 80 grit for adhesion, make everything clean prior to applying filler, using Duraglass as the base coat is a good idea since it will resist cracking and finally I would apply the final filler in thinner layers. I assure you that I could do a repair like that and it would last for many years. Notice I didn't say Bondo. I never use it. I use Evercoat Rage Gold. I think it is the best. Would I do a repair like in #27? NO! I have been welding in patches for about 20 years, but not everybody has a welder. Some people have to make patches the hard way. Before I knew how to weld, I have made patches with sheet metal where I cut out all the rust, tapped the edges of the hole in a bit so I could pop rivet the patch in and have the rivet head below the level surface and then used filler. Some of those patches lasted at least 15 years.
What will NOT work is some of the patching you see on YouTube (like the rusty wheel well lip in #7) where they just hit the rust with a wire brush, tap the bad area in a bit and then pump in the filler.
LET ME STRESS that I am saying that welding is definitely the best method of patching, and I am not saying that I accept the picture in post #27 as being done 'properly', but " Sometimes we gotta do what we gotta do."
Yes but we " gotta do what we gotta do." sometimes to do a no-weld job and sometimes to do what we want to do and what we want to spend. A person doesn't have to replace metal as they can choose a different route.
 
Bondo or any other brand of body filler is NOT a "Repair". It's a means to get you that last mile and get the panel flat. A truly skilled metal bumper can get the metal to a point at which zero filler is needed, but that's rair. Lead was the prevailing "filler" when everything was done by hand. Ideally filler should only be used to do a final skim of an area, and NOT span unsupported gaps. When I went to school, I was told no more than the thickness of a nickel and that was for production shops in which time was crucial. If you have the time, do it right. Foam is just stupid. Anything that's touching the metal that can hold any moisture is going to cause rust full stop. Now days we have epoxy which is meant to seal the metal. Even then if your shop conditions are right and you can get things done fairly quickly, you don't need epoxy either. Lots of cars running around with 30 year old paint jobs using just regular "primer".

Some state laws would argue that point. Check your local laws
 
Yes any dtm primer is fine on good metal, it doesn't have to be epoxy. There may still be some info coming newbies can benefit from?

That's correct. Some states require a "backer strip" to be added when replacing a large part of a panel to give the patch panel something to be welded to from behind, similar to overlapping. This is for extra strength, stronger than a butt weld. This is to keep the repaired and attached patch panel from becoming a projectile during an accident. You can just imagine some of these repairs he's talking about literally exploding on impact. Who knows where the pieces will end up? Cutting someone in half, perhaps.
 
I think it's been an interesting conversation. Both sides have made good points. As long as it is a civil, respectful conversation why censor it?
If it doesn't remain civil and respectful then censor the offending party.

There may be laws that pertain to a business .

yeah, just like you can drive a bus with your feet. but that doesn't mean it's to be done.

you're at best a troll. more likely though you're just a delusional hack.

i'd say good luck with what ever you do, but really i don't hope that for you at all.

Then I suggest you read the laws in your state.
As the apply to business and private sales.



In Missouri, selling an unsafe vehicle is illegal if known defects are not disclosed, as this can be considered fraud and may result in legal liability
. Used vehicles must have a safety inspection certificate before sale, with exceptions for vehicles sold for junk, salvage, or to other dealers. Dealers are required to disclose accident and salvage history, and the failure to do so can lead to fraud claims.

Disclosure requirements and what's illegal
  • Disclosure of known problems: It is illegal to sell a car without disclosing known defects, and this can lead to legal liability.
  • Accident and salvage history: Dealerships must disclose if a vehicle has been in an accident or has a salvage title.
  • Fraudulent practices: Selling a car with a tampered odometer, without disclosing flood damage, or without a title are also illegal fraudulent practices.

Inspection requirements
  • Mandatory inspection: Used vehicles must be inspected before they are sold, and the seller must provide a safety inspection certificate that is less than 60 days old.
  • Emissions inspection: If you are in a specific area (St. Louis City or Jefferson, St. Charles, or St. Louis counties), an emissions inspection certificate that is not more than 60 days old must also be provided.
  • Exceptions: A vehicle does not need an inspection certificate if it's being sold for junk, salvage, or rebuilding, or if it is being sold at a public auction or from one dealer to another.

Your rights if you buy an unsafe car.
Also suggest you ready the buyers rights.
 
Structural repairs that make a car unsafe maybe. Cosmetic repairs seems complicated. What about fiberglass fender flares, hoods, spoilers or the entire body of a corvette?
 
Seems a lot of yall want this nonsense to continue on. Let your voice be heard.

My vote is YES it's time to close this thread!
It's not nonsense at all. Just as an example - If a person has body issues on their car and it would cost 10 times more than the car is worth to have someone repair with metal , why would something they can do themselves that would make more sense, be nonsense ? Or even if it only cost what the car is worth.

Looking at the video I shown and knowing what it would cost to have that repair done with metal , it would probably not make sense to pay to have that done. Just looking at that as an example and not looking beyond that. The sensible thing to do may be to fix it as shown.
 
Then I suggest you read the laws in your state.

Yeah, I wouldn't check into any of that as I would only use fiberglass/bondo on certain areas . Do you know of anybody that checked into any of that before doing fiberglass/bondo work on their car ?

Ignorance is bliss your call. Locking troll thread .
