My 250 will blast and coat all the steel and aluminum on your kart minus wheels ,i tell all my people bring everything you want done and thats everything disassembled ,use a little common sense. most of the time were tradeing stuff (BARTER ) IM A RACER ,FLATHEADS no new equipment all rehabed . I will tell you if your chassis wasx red and you want it white ,if it was powdered correctly the first time ,i really dont want to mess with it . Dont care ifvyou blast it burn it or drage it around the yard you cant get all the red out of the metal ,you have to recoat so thick that it wont pass an impact. Test,which brings up the clears and candys . Ao good powder job is around 4 mils thick this is optimum for adhesion and impact resistance as stated by ppg ( the best powder on the market) so if i want candy i have a base color ,3 mils hopefully i got uniform coverage but im trying to keep it thin because we all know a chassis flexes. Candy effect 3 mils if im lucky more like 4 tovget uniformity, now all the candys need some clear hope fully 3 mils will go on and cover .from e xperience it wont usually ends up around 6 in some spots ,of course these are critical areas that are going to ckip. My point is 10 mils is not a durable job . Do alu wheels much better results but the wheels need to becready for it ( polished to a shaving mirror ) eliminates the base .acid wash with a gray scotch brite ,immediate warm water rinse ,another wash just to.make sure all the silicone is gone warm water rinse air dry ,mask the edge and flage preheat let cool to below 80 degrees powder xand cook i go 415 for 2!mins let it cool back below 100 ,light coat of clear ,heat to 415 for 14 mins dont bring them down fasr let em cool slowly (20 mins) and you should have a nice loohing wheel thats durable. Now lets talk about what heat does to tubeng ,daily i see 1 1/2 steel tubeing in 20 foot lengths warpped as much as 5 inches over 20 feet not every pice does it but some do ,its true that my oven will not approach tempering temps .however i beleive it does changecor at least alter surface tensions .ram me if you wantvim just telling you whatvi see daily these are welded and nonwelded pices ,yes a lot of it has to do with how thecwelder welded it but that doesnt explain plain material ,my point is if your chassis was free last year it may be a litte tightvthis year . My crew chief shakes his head every time he sees on of my "projects" and yes i tell my race budies about this before we get into the color . Ive done serveral full sized (lmsc) chassis and a fewxclips but these cars have a suspension to compensate for whatever happens. .justcwanted to share some info with you guys . Im bitting nails and prepping tires waiting for. March,if onlyi could find a woman that smelled like trac tac and tasted of thorvoil id be in heaven
