Solid advice. If the vinegar mix worries you, 70% isopropyl alcohol on a microfiber cloth works well on sticky soda and flashes off fast feather it over the whole panel to avoid tide rings and test in a hidden spot first. Use cedar shoe trees while drying and finish with a brass/nylon suede brush to reset the nap and then protect with a fluoropolymer suede spray in two or three light coats rather than one heavy blast.
Think about how you work rather than chasing fancy gear. Tubes beat jars for beginners because less air gets in and the paint lasts longer when you only open what you need. Student grade is the sweet spot for vivid color on a tight budget and you can get plenty of hues under twenty.
If fast drying worries you,, lightly moisten the surface before laying in color and take short breaks with your mixes covered by a sheet of parchment or even an upside down container. Store tubes with caps wiped clean and keep them out of hot cars or sunny windows so the paint stays fresh.
