I re-painted a trailer of mine using etch primer & a gloss car paint a few years ago. I didn't spray it as I hadn't got the equipment or a suitable place to do it so I used a roller
. The roller I used was one of the small gloss ones & it gave a lovely finish. The coat had very few marks in it & it looked a quality job. I painted the trailer blue with a grey roof & framework & the bottom 60cm of the body also grey & the mudguards black. IT looked really good. I think the paint etc cost me about £70-80 & my time which cost nothing.
I bought the trailer for £500, it was sound but had oxidised drab paint. I used it for 3 years & sold it for £800 to the first person who came to view.
I'd do it myself but have nowhere suitable at the yard to keep it covered for the time to paint it, has anyone paid a commerical company to respary one, if so how much was it?
