How to paint MDF to a mirror finish worklog

I went to Halfords today to change the beige filler primer for grey, but the guy at the shop told me they don’t do grey filler primer and I’m supposed to do beige filler primer then normal grey primer then black paint. Does this sound right or should I not bother with the grey?

There has to be some place around you that has it. Did you try automotive stores? I don’t know what Halfords is. If you can’t find anything you can probably get by with the beige if you put a couple coats of black over it.

Halfords is sort of an automotive store they sell mountain bikes and car stereos and car maintenance stuff… there’s 1 other store in my town more specialising in car stuff. I’ll try there tomorrow.

If you can’t find it there go to a hardware store. If you can’t find it there I would probably just put the black over the beige.

sorry, what sandpaper did you use to sand the colour coat? still 400 or did you move up to 600?

damn, I cut through the clear coat all the way to the mdf on my last sanding session… I have to touch it up too before any kind of buffering… It’s such a delicate and time consuming process…

anymore update?cant wait for second coat

Ok here’s the thing. I actually don’t have any extra 400 on hand so I used 600, but I said 400 because that’s what I would have used if I had any. So use 400. I wouldn’t ever use 600 until the very last coat of clear. I just have 600 lying around and no 400 so that’s what I used.

Indeed it is.

Sorry I didn’t think anyone was still following this thread so I held off on the updates for a little bit. The next few won’t be anything different though. The next color coat will look exactly like the first one, and the clear won’t look any different either, and the sanding techniques for all of them are the same. So I was gonna wait until I started finish sanding the last coat to update any more, but I will continue with every step if you want me to.

would like to see more

Ask and you shall receive. Not today though because I’m going to sleep now. I’ll update tomorrow though.

instead on using 600 before the last coat, does 800 or 1200 works? I think see big difference in 400 and 600 but the 1200 is simply tooo fine

I’m still following it.

Anything finer than 400 will make no difference at all if you have more coats going on. 1200 is not even for normal sanding. It’s used to remove scratches from previous sanding. Not to sand all by itself.

Duvet77 - I’ll keep updating for you guys.

Please do, I’m watching the thread too.

Plus it’s good for future reference once it’s all completed.

I just royally fuc*ed my paint job… The corners got me! Even though I could sand the whole thing and start over, I don’t have much time too paint. Grrr. Maybe a matted finish will make it okay…

Ouch. I’m sorry to hear that. I can’t stress that point enough. Be careful around every edge! I doubt anyone would get it right the first time though, you learn from experience.

dont open the thread if you cant complete it.geez procastinator

I’m going to finish it. Just been really busy with real life. I’ve worked like the last 10 days in a row. I finally have a day off today so I’ll be able to update a little later today.

Updated with the second color coat. There’s nothing more I can do until that coat dries in a few days.

so whats the minimum coats to reach the mirror finish?

One question, I dont need stain on my wood so do you think I can go straight for gloss poly for every coat?
