I have a Humvee that I am getting ready to apply SPI epoxy on. It was blasted and then had to be pulled outside for 2 days and it rained. Went back in my shop and sat for a year and a half. I shouldn’t have blasted it until I was ready, but didn’t know enough then. I tried an orbital sander yesterday with a 40 grit disc. It was already on it and I thought, what the heck, I’ll use this one up. You can see in the picture how it turned out. It wore through a disc in that small of an area. I was applying some pressure.
My questions:
Will sanding it down be good enough, or do I need to blast it again?
Should I be taking it down farther?
Could I use a belt sander, to knock it down faster. Most of the areas are flat.
Would one of those drum sanders, like Eastwood and Porter cable make, work better or easier than a DA?
If what I’m doing is fine, what other prep should I be doing before priming?
Do I wipe it down with SPI 700?
How quickly does it need to be primed?
I can’t see myself getting all of the sanding done, and priming, in the same day. I’m 57.
Would I be better off doing it in sections?
I know if I do it in sections, I have to worry about the 7 day timeframe.
I know this is a long post, but I don’t want to screw this up. Thank you in advance.
