Automotive Paint -What can't you mix? How long can it store?

Not to mention that understanding the whole concept and principles of body work and paint prep would take years of practical expericence to gain a full understanding of how each one is different. I'm not trying to down play your end goals here, but you have much better success and a better overall product if you put your VERY HARD EARNED dollars into quality products from ONE paint line. Mix and match paint products usually is a recipe for disater and ends up costing you twice as much in the end because you tried to cut corners. Remember body work is EXPENSIVE,materials are EXPENSIVE, ans supplies are (you know whats coming) EXPENSIVE. So my two cents worth is either bite the bullet and pay for a quality job, educate yourself on the proper techniques, and materials needed for a quality job, and save your self alot of headache later on because your paint is reacting with your undercoats and bubbles up, peels, falls off or what ever else my happen. Body work is just like anything else the more time and effort you put into it the better the results will be. Now all this aside there are some very affordable products out there that will deliver outstanding results if used properly, such as Kirker, UPOL, and others. Hope this helps.
