Thanks! I am well pleased with the results so far.
I might wet and dry it eventually, but not really bothered for now.. It looks plenty good enough..
Any gloss rollers (high density foam) will do, I have just been throwing the trays and rollers away when I have finished with them, they were about a fiver for a pack of five rollers and the trays are about 90p each from Wilko's. I also bought a pack of foam paint brushes.
I bought a 2.5L tin of paint, two thirds of the van has had one coat, I reckon there's just under 2L of paint left. You thin the paint with about 10% white spirit. Its amazing how far it goes.
Some people put two or three coats on, sanding between coats. I have got so much paint left that I am gonna leave it as is and see how it goes, its easy enough to do a bit more at a time (or repair), and there are so many seams to blend into on the T25 that it would be really easy to do.
You definitely need two people when painting, one to paint, one to follow looking for runs, as long as you get it on even it flats itself. The painting is the easy bit, its the prep work that takes the most time...
Is it a T25 your planning on doing?
