agree; only thing I would add is if the epoxy primer and sealer are vastly different shades, you may end up with a slightly different shade of topcoat on the trunk than the exterior. also, be sure to scuff the epoxy well before the topcoat
Good call. I will have to find an epoxy sealer that is similar in color. I used white epoxy primer for everything and the top coat will be Mexico Blue. No paint expert here, but I would think a light epoxy sealer would be ok to use under that color.
Just use the same products in the same order for the trunks as you will/did on the exterior. Or if you're not painting the exterior, than just accept that the trunks won't match exactly.
Using a tinted sealer/primer is less necessary if you're using quality paint. Cheaper paints tend be semi-transparent, so it takes more coats to cover up any variances (and by variances I mean like the yellow trunk with gray stripes above). But if your trunks are all primered in one color and you don't have variances then you don't need to worry as much about that transparency issue. Or just use a good quality paint and use 3-4 good coats.
Primer color
will affect the final color, but there are a bunch of other aspects that affect final color, such as: Paint brand, mixing ratios, number of coats, skill of the painter, even age (old PPG paint won't necessarily match new PPG paint, even with the same code). There are a VAST number of reasons why the only REAL way to make sure everything matches is to do the whole car at once. Or train a long time to be good at color matching (it's a skill far beyond paint color).
People pretty regularly get the impression that the 'paint code' is some sort of guarantee of color accuracy (I thought the same thing when I was starting out), but as your dig deeper into the process you realize what a sham the paint code is. It's only ever a
ROUGH approximation of the right color.
