<b><font color=green>yes,no,yes,no,lol,you have everything right BUT:
95% to 97% of my wax goes on cold,hot only ifen I want to show off alittle.Know the type dirt yard your talking about,thats where you do not want your wax to bead up alot but more of a sheeting,if your useing the W-200 it will sheet more so if you mix it weaker.Try mixing 2 oz to 5 gal and cold rinse twice that way without turning the wax off on the second go around,should not need a third rinse.Just b/c it doesn't bead up does not mean there is no wax on the surface,you should see little streams of water running off or sheeting off in areas,not all over.The stronger you mix it the more beads you will get which will take more rinseing to get the soap out of the bead and dust will stick to the beads.I have mine mixed 8 oz to 5 gal.,applied cold in the first rinse,then a secoud rinse without the wax on all trucks.If appling hot to truck I turn the valve half way on.When applied hot with the 8 oz it will bead alot alot alot more but will take an extra rinse or two also.PLUS I DO NOT TURN MY WAX VALVE ALL THE WAY ON,just so so 1/4 turn,1/2 turn.3/4 turn as in metering,depends if cold or hot as the amount I turn the valve which is a pvc on and off valve.I turn the valve 1/4 turn on all the trailers and do not have to rinse after appling..Wax is one of the hardest chemicals to ajust then any of them,not many people can apply it right as the reason they do not use.If appling to a whatever and you see its not strong enough do not reapply to that truck to ajust your mix,ajust it on the next truck or the next but never reapply trying to ajust the amount on the same truck(want work and it takes longer to ajust the amount).
Polished:
O K this is where the flashing will help you get that tail gate looking good,all tho its polished you can flash it with the HF as long as you keep it moving over the area and not appling a great amount at a time,,on and off.If I have it pictured right it will take maybe 4 or more flashs to get that tailgate clean.Then again it could be a type that cann't take alot of flashing on the first go around,if it is,do not flash nomore then 2 or 3 trys.Do it again the next time you wash it,what your doing is letting the metal calm down.If Diamond plate make sure you keep it moving or it will put streaks where it runs down the diamond,on diamond plate flash it and keep going from bottom up bottom up as to not let it run straight down,not a place for the hot flash.Please DO NOT use my mix rate but just for a thinking point b/c all rigs are not equal in they're draw rates as in different ways of plumbing.Tar I use the R-103LX,its a chemical you mix with diesel or some use WD40 but think the other is more saver as in not doing harm as the WD40 will to paint and other finishes.
Never use dish or laundry soaps on a painted surface,it strips the wax off plus dries out the oil in the paints,it gives it a dull look after it dries if not rewaxed.Wash one arm in the dish & laundry soaps and wash the other in reg. bath soap to get my meaning.
O after you learn the flashing it will work also on hardwater stains on brick,wood,ect. as in hot flashing the stain.
Another thing ron is don't get upset b/c things don't clean as you would like for them to or feel bad b/c it doesn't come clean,it takes time to learn to clean as it did to swing the tire hammer.Anybody that learns how to clean trucks on dirt as my blessing b/c when they get on dry gravel,chat,,or just dry they can fly around a truck,,thats one area thats costing you time now b/c of the dirt or mud.Tell them if they don't want dirt in the floor to bring in 3 or 4 loads of chat,heck they have the dumps wouldn't cost them that much.
