Enamel base coat + TAMIYA Panel Line Accent = ???

Hello All, This is my first post, and I thank you in advance for any advice. So here's the deal. After spending several weeks researching how to do panel lines, and a failed attempt at using markers and self mixed washes to fill panel lines, I found TAMIYA Panel Line Accent premixed washes. I watched a bunch of videos on how to properly do them, and it seems simply enough. Essentially just a wash with consistent mixing. Ive used washes in the past, but never for panel lines. Like all self mixed washes applied with a tiny brush, there is almost always the "spot" of paint where you set your brush down on the line to apply the paint. These spots are causing me issues. The TAMIYA Panel Line Accent is enamel (solvent) based, and I use Model Masters enamels for my base coats, which is also solvent based. All the advice ive seen talks about using thinner on Q-Tip to clean away the "spots" from the was application. However, as I use enamel paint for my base coats, I have experienced problems with putting thinner directly on my base coats, even in a small amount. So my question(s) would be these: 1: Is there another way to clean these "spots" off my base coat without the thinner damaging (dissolving) the base coat? 2: Are there good, solid colored lacquer sprays I can use for a base coat? 3: Would applying a lacquer clear coat OVER my enamel base coat be a good idea? (Since once the enamel is covered with a lacquer coat, the thinner used in the clean up of the wash "spots" would not be an issue) I will end my post again thanking you for taking the time to read and render any advice. And also take the opportunity to say that i have been searching high and low for specific answers, and could find nothing. My Best,
