Thoughts on Media Blasting Interior of Cab
I started working on my cab and getting all the components out to start doing a few repairs. In some places, the floor is pretty rusted with some pitting, but is solid. I poked at it with a phillips screw driver and didn't poke through. But, I am not sure I want to patch areas and weld through or next to the pits. Sanding won't get to the rust out of the pits.
I am considering having the inside media blasted. For those who have done that, any pros and cons to having this done? Did it warp the sheet metal anywhere? Did you have a miserable time getting the media all out of the cab? Did it make it easier to do repairs? Just wanted to hear about other experiences before committing to having it blasted. Rob |

I had everything sandblasted at the time, and there were still spots that I hadn't seen.
Yes, repairs are easier, I didn't have to scrape off any old paint, rust, glue or sealant residue, the sand residue could be blown out, but I also opened up pretty much all the cavities. There is a lot in the roof frame/window rear wall. Regards Harald |

I bought a pressure pot blaster and did 100% of the entire truck myself, in my back yard. It took about as long as erasing the paint by pencil - a LONG time.
You'll want a fairly good compressor - I have a 240V 2-stage 5hp 15cfm compressor. You could always rent a compressor. I blasted at 60psi, and had no issues with the sheet metal going wrong. Zero issues. The commercial jobs have MUCH larger compressors and nozzles, and can be pretty ham-fisted if they don't know what they are doing, and you'll know if they don't when you get it back and it's all wrecked. Advantage of buying a blaster yourself is you now have it to do other jobs, and you can use it again to remove surface rust after you are done the sheet metal work. From my '61 build's play list - THIS VIDEO (and two following in the play list) is the blasting. |

How long did it take you to do that hood? I am not sure I have the compressor capacity to run one of those, but I do have a ton of small parts that should be blasted. It would be very nice to have a blaster. I am looking around my area to see if I have options to use others blasters. |
Re: Thoughts on Media Blasting Interior of Cab
The hood took four days, but they were not 8 hour days. You could count the number of times I go through a bucket - it takes me an hour to blast through a bucket.
The cab was 40 hours, if I remember correctly. The frame might have been around 20 hours. I probably wrote in the description how long because I can't remember anything. Too much 60's during the acid? A sand blaster needs volume. I don't know how fun it would be with much less cfm than the 15 my unit puts out. On the other hand - if you are going to spray, it helps to have a good compressor too. |

I blasted most of my truck. I used glass beads and crushed glass. No deformation worries and it works great. I also built my own bead blast cabinet out of a 55 gal. drum, and I have used it a lot for smaller parts. It sounds like you will definitely need a larger compressor to do what you want to do, you won't regret it.
