Re: Sanding the cab.
Wow. That is not a job I would want. I would pass on the sand paper and find a sandblaster. I have used a wire wheel previously.
Are you sanding the cab (thread subject) or the frame (thread body)? Last edited by Alex Hayley; 11-04-2010 at 03:53 PM. |

Re: Sanding the cab.
No problem. I have made worse mistakes. I don't know anything about sanding/preparing a cab but that is getting close to being the next task on my list so I am interested.

Re: Sanding the cab.
I have found my Dewalt electric DA sander to be indespensible in removing old finish from metal. Just start with 60 or 80 grit and work your way to a finer grit from there. Don't be tempted to use it to smooth out bondo, though.
Leave that work to a long sanding board. A DA sander will cut into the bondo too much and leave the surface wavy. Rollock sanding disks on a die grinder is good for reaching into corners. Have plenty of elbow grease handy.

Re: Sanding the cab.
Would this http://www.deltaportercable.com/Prod...roductID=15050 be considered a DA Sander?

Re: Sanding the cab.
I always start with Aircraft Stripper. Get the good stuff at Napa instead of the cheap stuff at Autozone. It saves a LOT of elbow work. Be sure to wear long sleeve rubber gloves and also wear eye protection.

Re: Sanding the cab.
If you want to maybe try a couple different things and see what works best for you, you could try and use an angle grinder and put a paint stripping/sanding disk on it. That is what I'm currently using on my cab and fenders and stuff and it works like a charm! Although I don't have the big power tools with air compressors and all that so I'am limited. The disks look like a blue hardened sponge. I've gone through a couple already, but for what tools I have, I believe it's the fastest (that I've found). Good luck!

Re: Sanding the cab.
Wow Thanks for all your input, I will try the good aircraft stripper if it helps to cut down on sanding time its worth a try! I will also try that paint stripper/remover disc it looks like it will help too, if all else fails I will sand it!

Re: Sanding the cab.
I started out to sand and scrape then found a metal finisher locally. Here are before and after. Makes things a lot easier.

Re: Sanding the cab.
I once did this by hand on an S10 - it was a miserable experience and my hands hurt for weeks!
That said, definitely start out about 60-80 grit on a DA. Another tip is to be careful about the pressure you apply - trying to work too fast / with too much pressure generates a lot of heat and you can warp sheetmetal. As long as you're mindful of the pressure, it won't be a problem

Re: Sanding the cab.
It depends on how many coats of paint is on the truck, if it is the original paint I would use a DA with 180 and I would never use a grinder it is too easy to gouge the metal and then you have unnecessary body work. If your truck has many coats of paint I would use stripper and then a DA with 220 to the metal. Body work is labor intensive and you can’t take a shortcut that is why body shops charge so much, it is more for the labor.

Re: Sanding the cab.
Not to Hijack the thread. - Roland, was the cab sand blasted or media (plastic) blasted?
I perfer media blasting on good/non-rusty sheetmetal.

Re: Sanding the cab.
