Thanks for the reply and tips, had a look through your van thread and you've done a nice job there. Like the colour scheme as well with the white wall tyres and subtle red detail
I knew it would be a big job painting the van this way but I didn't realise just how big a job it is, the prep without filling has taken around 150 hours so far. With painting the high-top it must be nearly three times the surface area of your van, the high-top being fibreglass doesn't help as they aren't exactly flat and straight! Even from what you've said I can't see me getting away with any less than three more coats if I want to flatten it back. I think my van is just to big for one person to do this way especially as it's a motorhome and has an extra seven windows in it as well as the rear doors having windows.
I'm going to flatten back what i've done then do another coat and see what it looks like but i'm fairly sure i'll just leave it like that. The slightly better finish just isn't worth all the extra work, the thought of sanding the van four times is giving me nightmares

. Luckly the matt black looks quite good just rollered I wouldn't get away with it so well if it was a gloss finish.
Really impressed with the combi-colour, great paint, could have done with discovering it years ago. A tip for anybody painting matt black is paint it in the shade or on an overcast day. I tried painting on a sunny day in mid january so it was still really cold (had two t-shirts, gillet, fleece and overalls on) and the paint still dried as soon as I put it on. Should have listened to what was said on the dvd!
