I'm building the Tamyia 1:24 F40. After a 6 month break due to other things (less fun) I'm back on the job and I need to paint the shell. I had done 1 coat already in Humbrol #19 (red gloss) but it came out very bitty, far from a perfect finish. THinking it was a problem with my brushes (oldish), I've rubbed it all flat and gone over with the ideal product (Tamiya TS-8 rattle can). This gives a reasonable finish but doesn't have good edge coverage because the F40 has some sharp angles i.e. the side vents and louvres, plus the small areas where I couldn't rub back properly have blistered because of the high solvent content. So, I've rubbed back a second time and used a dremel tool to clean up the shut lines and fine detail etc, and gone back over with a new tin of Humbrol #19 and new brush. Much better finish, but

48 hrs on and the paint is still tacky.

Q1

What has gone on - paint was well mixed, no application issues as far as I can remember

Q2

How to sort it

I'm thinking hair dryer, but I don't want to soften it and cause runs and I can't find any useful product info on Humbrol website. Evens whether I get better advice here or there, I reckon.

I've been building models like this for over 20 years but have never had this issue with gloss before. Quite embarrassing as I work in coatings myself!

VOC 2010 strikes again?

I've decided on the hair dryer route followed by brake fluid if it turns into another cock-up.

DOT 4 or 5? wink

Thanks!
