Im starting to repair my dash which is really rusty. i dont want to pull out the gauges and stuff so i though i would use a sander and not a blaster, i was wondering which set up i should go with. another thing im going to blast the rest of the inside cab because it to is rusty and was wondering how should i cover up the gauges and windows, im not going to blast anywhere near them i just dont want to risk breaking them somehow.
