HELP!!! my dull coats dont work!!! y!!! WHAT DID I DO WRONG!!!!

ok i have used the testors dull coats, get a semi gloss finish (DO NOT WANT THAT) Ive used some stuff in a bottle, turns my models yellow. I have tried some stuff i bought at home depot. makes my models have a bumpy gloss surface. Y cant i get a dull coat that works??? what am i doing wrong to make my dull coats gloss???

You may not be shaking the Testor’s Dullcoat up well. If it is not mixed well, it separates out and the dulling agent settles to the bottom. I have used it with no problem.

my arm hurts from shaking, do you think i got a bad batch or something??? the hobby shop is in riding distance for my bike, itll take about an hour to get there though so i dont want to go if i dont have too. thanks, any other ideas on why this isnt working?

Not sure, I can’t think of a reason why it isn’t working for you. I have never had a problem. Good luck.

Rattle can? Not the best choice since you can’t see the amount of evenness in the solution.
Appropriate level of thinning? Should have the consistency of milk, at most, before airbrushing.
Temperature? Especially for rattle cans. Too cold will leavea too glossy finish. The stuff dries fast enough to test it on scrap before committing it to your finished work.
Bad batch? Always a possibility.
Home Depot? Where does that say Hobby? Avoid it. "Stuff in a bottle turns your models yellow? What stuff is that?
I’ve used Testors Dullcote (and Glosscote) for years witout a problem. Well mixed dull gives an absolutely dead flat finishe when airbrushed properly. Enough so that I can use a variety of paint finishes before dullcoating and I regularly take figure awards throughout the region.
