I'm planning to fix the roof (for lack of a better word) first, then get rid of the gaps between roof and cowling, then paint. So I need to do the "inner" paintwork first, otherwise it will be impossible to reach when the roof is in place.
Roof fixed.
Paint is Tamiya TS-8 straight from the can, just before sanding and polishing. No clear cote.
Had a lot of these spots where the paint just does not want to go. Don't understand. The part was sanded, washed, primered, sanded, painted -> bad spots. Sanded everything down again, washed, primered (no signs of spots after primer...), sanded, painted -> again these spots!! This time just on the underside, so I'll leave them.
Those look like Silicone divots, where paint reacts with some contaminant on the surface and then produces those small depressions because the paint is repelled from that area. Sometimes resin release agents can cause that, even when the part is well-washed and clean as we like it to be, there's still some residue there. Since it's on the underside I think you're right not to mess with it because it's not that noticeable, but if that were an upper panel I could see why it would be a problem.
I'll remember the fisheye eliminator for future projects, because I'm now working straight from the can.
One thing that still I find strange is that there was no sign of any problem after primer.
The spots might be treated by placing a little drop of paint right in there with a brush. If you decide to sand & polish anyway, that probably should work..
There are 2 main reasons for such holes usually, silicon on surface or water in the compressed air. But as you are using cans, the second reason is out.
A 3 reason on resin parts is gasing out from resin, same like on fiberglass parts, when i have such nasty parts i sand them down again to the material and put it in an oven on a low temperatur, this can help maybe. Special sealers for real cars are around on the market for such cases, another way i sometimes go when i don`t have these sealers is to put a thick coat of clear on it, and sand it back till the hole is gone.
I think you get it fixed, heads up Marcus
A lot of invisible work today, finished the inside of the front cowling. Luckily the fit is quite nice, I'm even hoping that I don't have to glue the pins that keep the cowling in place.
In the meantime I did some work to get the rear ready for painting. I noticed the front cowling paint (also three days old) is still susceptible to finger(and other)prints. I think it would be best to wait a few days to let the already painted part harden before covering it with masking tape -- but I'm in the "let's get this thing finished!" mood right now...

Thanks for watching,

Last time I was in such mood, I was trying to rush my MFH F1-GTR build. Never been happy that I took that approach since.
Lots of good work was negated by some last steps, which gone wrong, because I was trying to get it finished fast. Hope my
mistakes will give you encouragement to not take shortcuts, that you could be quite unhappy with in the future. Amazing
work so far.
Thanks for your concern No worries though. I'll finish the front end first, then move on with the rear later this week. By that time the paint coat is a week old. Even without hurrying, the car could be ready in 2-3 weeks. (within my schedule...)
