I have my "Rock Rails" off my Jeep Rubicon in for sandblasting. Both the outside and inside will be sandblasted. Rock rails are like 5 foot long steel triangular hollow tubes. The sand blasting can't do a great job inside of the tubes because it needs a 45 to 90 degree angle to really hit an area, thus the inside won't be down to bare metal or even close and there is a lot of rust. Thus, I am faced with sealing one end with say duct tape and pouring in the RustBlast and sealing the other end with duct tape and moving them around constantly for say an hour and letting RustBlast do it's magic. Two questions:

 

1) Do you think this will work?

2) How much in quantiy do you think I'll need to do two 5 foot long rock rails?

 

If you have any ideas better than the above I'm eager to hear them ...

PS: These are what rock rails look like (they have plastic end caps on them in this picture which I will put back on when process is complete)

 

The best way to do the inside is with Cavity Coater. It is very forgiving if the surface is not perfectly prepped and it gives you amazing rust protection.

Please let us know if that helps and if you have additional questions.
