Painting entire cj body

I'm buying a spray gun and was wondering how many gallons or quartz ill need to spray the whole body and underneath as well. I was planning on using a self etching primer on underneath then coating that. Te body just gonna prime and spray then clear coat. Any help much appreciated. Never painted a car before.

That really all depends on the paint itself,all brands have different qualities of cover and pigments in them,1 brand might need a full gallon to do a full color on a CJ5,others may need 1/2 that,best to ask the manufacture or Paint supplier where you are buying it.

I also depends on the gun too,some use less material than others,some are really air hogs and waste alot of material in overspray

I generaly always buy a Gallon kit for the base coat.

Another thing to remember,different brands have different Mix ratios for the catylist and reducers..for example..if 1 says it is a 1:1 mix,you'll get an actual 2 gallons of paint in a gallon of color,if its a gallon and mix ratio is 4:1,then you'll have 1 1/4 gallons.

I personaly wouldn't bother with a self etching primer underneath,just buy at least a 1 gallon kit of a good Epoxy primer,Epoxy primers have a metal etching benefit and will be the best primer for the whole job.

In general....it's always best to have more on hand than needed,in case of screw ups or mis-calculating and even having around for any repairs later,nothing sucks more than being in the middle of a paint job and running out of paint

This was very helpful. I appreciate the insight. I was looking at one primer and it was 1:1 so I guess that would be two gallons. I'd use same primer on body and underneath but I was going to use black underneath. Don't know if this would be good on body as I don't know what color I'm doing. Any spray techniques or body filler?

All guns will have a different size spray pattern according to several different scenarios n such..different size tips,air pressure required,type of paint..etc...,just play with it untill you get a nice even oval shaped pattern that covers well but not so much it runs easily.

As far as body fillers,any will do good,just try not to use it any thicker than 1/8"..i know some say 1/4" is fine but not to me,more chance of cracking and falling out later.

if you have rust holes,cut it out and weld in new patches,if you have no welder or can't or don;t know how to weld panels in without warping bad,then cut out the rust spots and have sheetmetal ready for a weldor who can.
Fixing holes and patches with bondo or fiberglass just creates problems down the road and then you are starting over again
