if your truck was rusting out and had a few small holes would you consider using "gl***" to patch up the holes. I understand the right method is to cut out the rust and weld in a new piece,but due to current restraints I dont have access to a welder.
I would say no. If you dont have access to a welder then prime it. throw a mat or something over it and wait till you can patch it right you dont need a expensive welder to patch. that just make more work to do when you can do it right or its one of those that will work i am not going to mess with it.
It's not the 'right' way to do it but hell yeah I'd use gl*** if I didn't have a welder! It'll work good enough to get you down the road till you get a welder. Are the holes problematic enough to warrant fixing at this time? Like the previous poster said, you'll just have to grind all that **** out when you can fix it right. When I was young and poor that's the kind of remedy I'd have done.
I've used Margl*** many a time during my misspent youth and it worked fine on pinholes until I could fabricate and weld in steel patches. Just clean the metal well with a wire wheel and use tape or cardboard on the bottom side to keep the 'gl*** from gooping through the holes. You'll learn to weld and fabricate soon...then you can re-do it the right way. Good luck!
A buddy of mine in high school cut the rotten floor out of his '64 Valiant S than used seam sealer and pop rivits to install a good floor out of a parts car. You had to know where to look for the rivits to find them. It looked like it came that way. Fast forward 20 years, (damn!), he still has the car, the floors are still just like they were and he's never been a problem. For the price of the resin and the mat ant the mess of fooling with gl*** I'd get the patch and glue/rivit that ****er in. Forgot to add; at the same time I put gl*** in the trunk of my '63 Impala. It lasted for a few years but. No matter how clean you get the metal under the gl***, it's going to continue to rust away and eventually rot out. I think it depends more on what you're planning to do with the car. If you plan to keep it 20 years do it right the first time. If you're just looking to have fun for a while do it almost right and go for a ride.
I say duct tape the holes till you can get a welder! Not to say the gl*** wont work in a pinch, but if you want it to actually stick, you will need to sandblast the rust completly away anyway. Even this will leave a repair you probably will not be really proud of over time. I used a lot of fibergl*** in my coupe about 25 or 30 years ago, it all stayed in and tight (I did sandblast), but I can't say I was ever really "proud" of most of these repairs... but it was all I knew how to do, and there wern't the resources then to get info on demand, (like the HAMB!). Starting in October I started cutting all of the gl*** out... It served a purpose for a while but... Anyway, I would consider tape for a while. there is some stainless steel tape that is reasonably rugged and durable, I use it to temporarily "fix" puncture holes in semi trailers, stays in and sealed for years if you need it to...
