Hi I decided to spray Derek myself. I spent loads of time preparing him. It went better than i thought. i bought a hlvp spray gun, mask etc primed him. That went fantastic. Flatted him all off........At this point i was really thrilled. My coats were even, i'd watched tons of demos on youtube, read alot....I've tried to upload pictures of him on here but i've can seem to do it.(directions would be great if anyone know how to do it.)
I bought zircon blue met. I practiced on a board for my fan, air, paint flow. Then i did the back of the bonnet and boot lids. It was going really well. Very even, no runs. so idid the whole car. I rang a friend who had done spraying before to say that its going on even but it seems a little rough.....He said that it is probably the met that i can feel and the clearcoat will berry it. SO i clear coated...............................It went on in the same even fashion.

I let it dry a week. then buffed up 12" square on the roof. It buffed up nice and shinny. but underneath the smooth shinny the paint still looked bumpy. Tiny tiny bumps.........My friend came and said that the colour coat had gone on dry........SO i decided to rub it all down again. Trouble is i dont know how far to rub it. I keep rubbing untill it feels smoth but i can still see dots of shinny so i rub some more. then i get blue coming off. and i dont know where the shinny is from the glaze or the metallic piant. Is there anything i can do to speed this up........thank you liz

i mean do you have to rub it down until it feels smooth or when all the shinny bits are gone?

What are you going to do?

Flat the entire car back and then repaint both the base and clearcoat?

If so you'll need to flat it back the car until its all nice and smooth and even(like you did with the primer coat before painting it)

Any shiny bits will need to be flatted or scotch brited back until they don't shine anymore, new paint won't stick to the shiney bits!!

Before doing the car again I'd have a practice on a single panel(boot or bonnet), go through the whole process and make sure you're happy with the finished result before doing the whole car, save wasting paint and getting all frustrated!!

Painting is a black art and not an easy skill to master so don't beat yourself up if you get it wrong first time!! Practise....Practise...Practise!!

Hello Neomilly,

Sorry but im not offering help or advise as i'm the last person to get help from with this stuff but I was just wondering if you could tell me where you got the clear sheets of plastic that you have hanging up in te picture that you have posted up?


Thank you very much and I hope you paint all goes well

From what you have put I gather you are spraying a metallic base coat, from my
basic knowledge of paint I am on the understanding you should not flat or touch
a metallic base coat as this will show through the laquer, If you do flat a section
then the whole car should be flatted to ensure a unified finish. Ideally the gun finish
should just be laquered over, so this should be a nice wet coat, not orange peely or dry...

I state to my knowledge !!!!!

I might get shot down!

[neomilly]

yes i think your right. The problem was because i 'thought the base coat was good because it was even and no run' i went straight over with the clear coat.......only because i didnt know any better. Its just taking for ever to rub back down...... arrrr well at least i'm learning plenty. what grade grit should i rub down to if i'm going to respray the base coat?

i got it on a 50m roll for £3.99 from wickes. although it is too thin. it is really worth getting the thicker stuff. i've got other stuff bikes etc on the other side of the garage so i didnt want any over spray. the thin stuff just blows about too much. and my bullmastiff dog just barged through it.'he's a bit thick!

I think around 800 grit should do , don't want to go too fine, my dads mate flatted his primer down with
a fine grit 1500 there abouts, after he top coated and laquered he noticed his paint had lifted on an
edge, so he pulled it and his topcoat and laquer just peeled off!!!!!!!!!, it hadn't keyed to the primer
as it was too smooth...

i have just put some of the start pictures of Derek on my facebook. i didnt know how to do them on here. my pics wont go on here for some reason but they went on there.

[Shifty]

If its a bit rought then maybe buzz most of it off with some 320 and then finish it with the 800 grit?
