Hi, i have been following this thread for a while...someone on MR2OC was talking about this 50 bucks paint job and he actually tried it...

so i first started with my friend's 280z..
and now i am working on my mr2..

here are some questions:
1.how come i keep getting bumpy surface after each coat? (the paint is so not smooth)
2.i already did about 6 coats to it, wet sand every 2 coats...so i tried going high grit wet sand and buff it with turtle polishing compound..it comes out with so little reflection and is not shiny at all...(i am painting black)..whys that?
3.has anyone tried to apply clear on it? and just wet sand and buff just like a sprayed paint job?

Sounds like you're either not using enough mineral spirits or you're putting too much of the mixture on each time. Each time I've tried with the correct mixture (very thin) and applying it very thin - just 'wetting' the surface, it has dried totally smooth, no orange peel. The wetsanding was to get rid of the imperfections mostly.

When you look at the surface really close, can you see lots of tiny scratches? That would explain the lack of shine. I have had some luck using either swirl mark remover or a stronger polishing compound, it will get rid of those tiny scratches and should shine better.

Here is a pic of those microscratches in sunlight. These are from 1500 grit wetsanding. Next time I'll finish with 2000 after the last coat, then go with polishing compound. This surface did not shine well unless at an angle. I painted over this particular area, but on another similar area I did get a better shine by applying some fast cut compound by hand (by machine would have worked much better, but even by hand I could see a difference).

guys i could use some help!

first coat applied to alitte to thick. so i let it dry for like 4-5 days. then i knocked it down with 400 wiped it down with mineral spirits let it dry then blew it off with airhose then applied 2nd coat much thinner then first. this was at 8:00 last night. Got up at 3:30 am and went to put another coat on and it started lifting up in small spots . I guess you would call it checking . to me it looks like the paint is cracking then it just lifts and gets all flaky. Its just small spots the size of a quarter and just a couple spots . I guess they can be knocked out with 600 when it drys good but wont these spots need to be sanded down more then the rest of the panel. This is just a practice piece so im learning as i go here. Im using profesional tint base stuff turquos. orderless mineral spirits also. im not having any trouble with bubbles or soft paint. my first heavy coat went on thick but once it died it was hard as hell. could it have been the air hose blew something on the panel before i rolled the second coat?

That sounds like what I saw on my little test area. I chalked it up to the outside layer being dry, while underneath that, the paint was not dry and the solvents in the paint ended up coming through the dried layer above. This can be a result of either putting the paint on too thick, or putting thin layers on but not giving enough drying time between layers.

This is what I was describing..




If I had any of this, I would be tempted to sand the heck out of it before applying any more layers, to make sure that uncured paint is taken off. Not sure if this is what youre describing but sounds like it..

First, is your compressor one that has oil in it? Second, do you have a water and or oil trap on it? If not then you probably coated your panel with a fine mist of oil.

When I am painting I always wipe down the panel with my thinner just before painting. I give the thinner time evaporate then spray.

I the case of the roller method, I would wipe down with the mineral spirits just before you apply the paint. Make sure you give it enough time to evaporate, before you start painting. Wiping down just before paint will take off any kind of oily junk that might be on the surface. That includes oil from your air line, or sweat from you

The other thing to remember is that if you don’t let the spirits evaporate long enough, they will still be evaporating whit the fresh paint on top. That will cause the paint to blister, or peel. I have done it before with much more expensive paint. I wiped down then sprayed right away. What ended up happening was the first time I got the car out in the sun, the solvent under the fresh paint started coming to the surface causing little blisters. We call that solvent pop. The only way to fix it was to strip down my new paint. NOT GOOD.

Keep trying you will get it. We are already seeing lots of you getting your technique down and seeing good results.

So what were your final proportions of paint and mineral spirits and penetrol? What ratio did you use?
