MDF painting tips urgently needed

I've just put the first coat of primer on with a 6" roller and it looks like absolute crap  :timebomb: !!

I'm using a gloss roller is the correct type? the emulsion one looked like a shaggy dog so I didn't get that one.
There are roller lines all over the cab, Ive tried to put the paint on lightly and not to push down hard on the roller but the paint hardly applies to the MDF when I do it like that.
I know that it still has to be sanded down and another coat put on top but I'm now worried that the top coat will end up looking like this, its just awful !!!

I knew I should have hired a compressor and sprayed it !!!

Negativecreep0:

well that is the problem with painting and not spraying.......... I'm assuming you are using gloss paint. Gloss paint makes every little line show. If you try semi gloss you may have better results. Or laminate..........

kelemvor:

Normal rollers that look real fuzzy, go down once you get paint on them.  THat's probably what I wuld have used.  But the compressor/sprayer idea I always wanted to try too but don't really know how those work.  heh.

MustardTent:

I just used off-the-shelf spraypaint from Lowe's (Rustoleum gloss black).  Works like a charm.   If you decide to go the spraypaint route, make sure you do it in a well-ventilated area and wear a mask.

I did just that, and I still found that the inside of my nose was black when I was done.  Stupid cheap paper mask  :)

Timoe:

Home Depot, or your local hardware store, sells a white foam roller that says Ultra-Smooth finish.  Its a small roller cover and not big, puffy or nappy.

That is what you want for a smooth finish.  Also, sand lightly in between coats with 200 grit sand paper.
