Freshly painted Door Questions

[toy fanatic78]

This is what the body shop recommended after my wife's car had some repairs done. Actually it all that she uses to put shine on the black 91. Any paint pros on here can comment one way or another.... Per 3M this contains no waxes or silicones and can be painted over. So this might "something" you can use while waiting for the cure... Again, I'll leave that open for the pros to comment on... A high speed buffer is not required either... which is a good thing...

This is what I was referring to as glaze,use a product along these lines to polish the clear.The sand scratches from 2000 grit are hard to get out with a glaze,you'll want to use an actual "buffing compound" for that (has a little grit to it),then follow up with the glaze to polish out swirl marks.

so you guys are recommending that i wetsand with 2000 grit
then buff with a good buffing compound
then polish with that recommended polish: by hand?
should i buff by hand or with a buffer which i already have

Start with 1500,this cuts dirt and orange peel better,then use 2000 to tone down the 1500 scratches(you can skip this step,just makes it buff easier)
The polish can be applied by hand ,or a buffer.Hand glazing tends to shine better.If you use a buffer,use a black foam pad for the glaze,using the white pads,or the same pad you use with the compound,it makes the glaze useless.

This little quote is what my concern was.
As these are plastic pieces and you say the rest of the door is fine. You
may be dealing with a fish eye prob. If you sand these they will look like
little doughnuts. And by the time they disappear you will be into you base coat.
There for it would be most prudent to remove mirror and door handle and
sand out the fish eyes clean with soap and water, dry, clean you hands.
Wash parts again with new soap and water and clean rag than dry. Clean
hands again wipe part down with reducer with clean rag. Hang and shoot primer. Look for fish eyes, none proceed to paint process. Any start at sandin
again. But first move all products like armour all to the other side of garage.
Wash hands ect..... hope its just a little orange peal:icon_bigg muzy

The type of plastic used on the MK3's is typically not prone to fisheye problems.
I think he may have been talking about dirt,hard to tell without some pics.Good advice on getting rid of fisheyes though.

You bet-cha Toy. Ya I agree on the plastic but... often the mounting gasket is visable
and some owners use stuff like armor all to clean the sliver that is visable usualy not with
a Q-tip, lol. Thats just where my head is :icon_bigg muzy

 

[toy fanatic78]

Gotcha,good point.So used to not using Armor-all type products on my vehicles or washing cars with dish soap very well before it gets anywhere near the paint shop that I forget.A lot of people don't know the effects that stuff has on paint/clear being sprayed.

Pick up a box of neoprene gloves at Auto Zone, O'Rielly's, etc. Keeps the oils in your skin off of your parts during your cleaning and painting process. Around $12 for a box of 50 pairs. Change them frequently.

Oh yeah: They don't have any powder in them, so they won't put any contaminates in your paint.

the mirror and handle were already removed during the painting process. the mirror is plastic and has no problems. i think it looks better than the door and handle.
the handle is metal and i actually messed up the paint (accidentally scratched the surface after it was clearcoated. i had to sand down and start over. the handle has fish eyes, but not in a conspicuous place so im not really worried.
all the parts were sanded and cleaned well and put into a "clean room" in my basement. i painted the door in my garage with a heater so the paint wouldnt run. i used a fresh pair of nitrile gloved for the sanding, and a separate pair for the painting... so nothing would be contaminated.

the finish that im trying to describe is just a slightly bumpy texture over the parts that i noticed when the clearcoat dried. i believe its orange peel... because i looks like the texture of an orange peel. lol

Orange peel and dirt specks will sand & buff out.Fisheyes typically wont,you'll burn through the clear first.

thanks for all your help.
to be honest, the texture of the paint isnt really a huge concern of mine. the truth is that the whole car needs to be painted and i just needed to match the color of the new door to the rest of the car. my door was damaged during a storm a few weeks ago and i picked up a new door and it was red, so i had to do something. the whole car needs to be painted eventually and i was somewhat experimenting my painting skills. the new door actually looks better than the rest of the paint on the car.... the hood and targa is quite faded.
i just wanted to know if there was anything else i can do to protect and/or improve the final finish of the paint. now that i have all these tips, i might just take the challenge of painting my whole car in the future. ill have to do some more experimenting

thanks
