Well I think you're asking an interesting question - - the best and cheapest way to paint
There are countless number of threads on here on what people used - and what they did to make their camper more enjoyable to them. Many say to use some cleaner and clean it up? Others say to pull all your windows
out and start from the ground up....
I guess that's what is great about this site - everyone has their own opinion and for the most part, everyone respects everyones opinion.
I started with this -
I drilled out all my rivets and fiberglassed over my holes. I then sanded down those areas and sanded all rough spots on my camper - and got to here -
Then I found this site: http://rollyourcar.com
I thought I would try this type of technique for my Camper -
so - I went to Menards - and picked up 5 quarts of Marine Top Side paint. 2 black - 3 white... thinking I would do 3 coats of white on top - and 2 coats of black on the bottom. I thinned the paint according to the website listed above and went to town on my 72 Boler
Is it perfect? - No -
Does it look better than what I started with? Definitely! And most important, is the Wife happy with the changes and is OK to camp in it?? YES -
For the cost - I don't think you can beat the price..... $12.99 for 1 quart of paint, plus $25 in rollers/misc items - -
For me Camping is something I do about 4 weekends a year, so the thought of spending several thousand dollars to do a paint job just wasn't feasable....
So - I have about ~ $100 into my paint job, and I'm sure I'll need to do some light
touch-ups as the years go on, but it's well worth it in my opinion.
Here she is today - - (I painted my door all white and it is on, but don't have a photo of it yet)
Best of luck, I (like many) - look forward to seeing some of the changes!
