I will be sand blasting and coating my frame and fender wells this weekend and need to know how much media I will need unless I can get away with degreasing and wirewheeling rust and putting a primer sealer over it?
I just finished sandblasting my frame and used 100 lbs of blasting sand. I did the frame, motor, springs, and axles. Think it was like 15$. The only part I couldn't get was directly under axles, since I still have the motor in, but will address later.
Do note that I used a commercial air compressor that u can rent from most rental places. I would highly recommend this, it will save u aggravation, time, and will be able to go nonstop. Bout 8 hrs total time, and when ur done u have a air pressure that's able to actually blow the sand out of the frame. I was really surprised at how much it put out with just opening a ball valve, I mean hold on TIGHTLY.... Nozzle was hot to touch when I was done
I wrapped a ez-up with painters plastic and on the ground, and was able to recycle 5 gallon bucket full, though I didn't use it
im doing it outside with my great grand fathers blaster he gave me. there isnt too much rust on the frame and still has the factory black paint on most areas. Im using duplicolor rust fix, undercoating for the frame and bed armor for the wheel wells. Should I put a primer sealer on the frame or just undercoat.
How many cfm's does the compressor put out?
How many cfm's is the blast nozzle rated for?
Is the blast nozzle new or wore out?
What type/size grit?
As others said, how rusty/greasy?
Do you want a white blast for a good zinc primer or a mediocre blast for like a clean sweep for a basic primer?
I used to professionally blast/paint ships, oil rigs, trailers and heavy equipment. Cost/amount of sand is immaterial as it is cheap.
