Question 1

Has anyone used a clear cost over this? If so, what kind is recommended? Reason I ask is due to marks left from bird droppings

Accepted Answer

USC makes a aerosol clear  3680061, However we cannot guarantee results, surface would also need to be properly prepped, scuffed to ensure adhesion

Question 2

The spray comes out somewhat spotty/blotchy, is there a correct way to clean it or is it supposed to come out like this?

Accepted Answer

Well it souldn't be splotchy; if the can is going to sit unused for over 20 minutes, invert the can and spray onto scrap until cleared of spray. If the nozzle is somewhat clogged, clean it up with acetone and a very find pin. Fine abrasive, paper or steel wool should clean up the already sprayed. I don't know if  acetone or some other solvent can be used after the paint has set up. Very clean surface is needed: no oil, grease, or hand prints.
Oh yes, shake the can for at minimum 1 1/2 minutes before using. That marble in the bottom of can really need to sound sharp when it hits the bottom of the can. Also, best use it at room temperature. If cold, test it first on a piece of scrap. Read the directions about how far the can should be from the surface. And read about the time between sprays.
I've used SEM 39143 for my old toy cars for years. Guess they can put out a bad can, so test spray scrap. Good luck.

Question 3

Can this paint be used on metal trim with out primer?

Accepted Answer

It is for plastic trim.  If you want to use it on metal I would use primer so it sticks well.  It will be a little thick after a few coats.

Question 4

Can cera trim....a ceramic rubber and plastic coating by Last Coat be applied over this when cured..thank you?

Accepted Answer

Most likely. Trim Black is a lacquer type paint and should not react negatively to being overcoated.
