Took my 71 down to bare metal with wire wheel and 5” angle grinder, used sand blaster for small areas that I couldn’t get with the angle grinder. Used endura primer and paint…I’m not too sure what we did wrong, the finish only last about 4 years in the places where we welded, 18 years later it needs to be done again, I don’t remember what the material costs were, probably between 400-600 dollars in paint and primer. I guess looking back on it, 18 years is pretty good for amateur body work. Here is condition now, thinking about taking tub off again, doing more work on the frame and re working the tub - but I just got this thing back, I’d like to enjoy It for a bit before taking it out of commission.
