Time for the front and back!
DONT FORGET TO WEAR GOGGLES AND A RESPIRATOR or you could die! darwin theory at work...

These pieces will take a little longer because they are textured. You can paint them as they are but your finished product won't blend perfectly with the rest of your bumper. I wanted it to blend as closely as possible. In order to do so I had to get rid of the textured effect. I did it the stupid way and sanded and sanded until I wanted to shoot myself for ever starting this!

So you must all learn from my lesson. Work smarter not harder!
It came to me yesterday when I was refinishing my wheels and had to use some filler primer. So instead of sanding all the little bumps off, which is hard to do even with an electric sander...we will fill them up with filler primer. Then we will sand them down which shall be much easier! Filler primer $5 autozone/shucks/you know

First put on a few coats of plastic adhesion promoter, who is your friend when painting on plastic stuff! Don't put on too much or it will leave little bubbly speckle things...if that happens wipe them off with a clean lint free rag. When you are priming, it is a good chance to practice your even strokes with the can and get the hang of throwing that paint on their evenly!

Then put on a few coats of filler primer until you have built up a good layer. Do this 5-10 mins after the ahesion promotor is on. The filler primer is supposed to be sandable in 30 mins or an hour, I forget. But be smart and don't sand it until it is completely dry!

I would hit it with some 400 grit sandpaper to get it nice and smooth! If you really wanna get silky, bust out some 600 grit. When it's all smooth, go wash all the dust off.

Now you are ready for color coat! Bust out your color of choice (hopefully to match the body color). While wearing respirator and goggles put on nice thin coats. Maybe let them dry 5-10 mins in between. We are just trying to prevent runs here. Runs = ugly paint job. At your discression, put on as many coats as you think you need until you can't see any red/black underneath anymore!

Looking good so far!! Go have a beer while that last coat dries up nicely so you don't put the clear coat on too soon and make the color coat run...That will ruin your day

Ok, color coat should now be dry or almost dry. Give it an hour or 2 just to be sure

Then whip out the clear coat. The first coat (as the can should say) will go on lightly followed by slightly thicker coats on top . Again we want that first clear coat to be dry or almost dry for precautions of the color coat running on us! Paitience is the biggest virtue while painting. 30 mins should be fine for wait time. Then come back and put on a little bit thicker coat of clear. Let it get tacky and then put on another coat of the same thickness. Now we are most likely safe from making the color coat run underneath. The pieces should be looking pretty darn glossy now too! Basically you are home free now. Let them dry for as long as possible up to 24 hours!

Put them back on, step back and tell yourself the usual, "Damn, I'm good!" lol

bada bing love cheap mods! [wrench] [az] [az] [race]Biggest mistake I would be careful of: Make sure the color coat is dry to touch or very close! Otherwise when you put the clear on it literally changes the shade of the color coat! Then your color match won't be so great! Goodluck!
