Hello mate,
Rustoleum is an enamel oil based paint that can be thinned down using cellulose (white spirits if using roller)
This is my experience using the stuff:
PROS:-
* If like me you don't have the funds to pay for a respray then combi colour costs £35 for 2.5 litres mixed to any VW colour.
* Any areas can be touched in using a brush then colour sanded.
* Rustroleum is a rust inhibiting / retarding paint and gives your van an extra protection that most paints don't offer.
CONS:-
* Body shops will hate you for it, if you decide to get a respray later on then Rustoleum will have to be removed as other paints may not adhere.
* Rustroleum takes an age to cure off so painting in a heated workshop or the summer is a must.
* The paint does not go as hard as say 2K so scratches easily.
Once I have painted the roof and bumpers I would like to experiment with lacquer, therustshop.com sell some interesting stuff called 'diamond finish high gloss clear'
If I was to start over I would of gone for 2K paint instead as it is far more superior though.
Hope this helps.
