using Rustoleum... questions...

[remmoc72]

Hi,  this is my first post so,

I am going to repaint my retro van with rollers with rustoleum and I know from what I have used so far it is very soft and clogs up sanding discs.. so after reading a few different threads on other forums I came across a few people adding hardener to the paint (obviously the correct one for the paint) and this apparently allows it to be sanded like 2k paint and also gives it a harder finish and seal.

Has anybody here got experience with the paint or especially with adding the hardener?? And also, would it be preferable to add some thinners aswell?

I fully understand that 2k paint would be the better option but the van is a ratty used vehicle that will need bits doing from time to time and being able to touch up the paint with the limited time I have would be great. 

Thanks for any help!

I sprayed an old Bug with Rustoleum, added thinners at about 1:10. Didn't add any hardeners and even before sanding it looked pretty smart. I think it just needed a couple of weeks between final coat and sanding, although I promptly sold it!

There's an 'Actual idiot's guide to rollering Rustoleum' thread on here. It has lots of good info and links to some other very good info.

I'm doing the same on my Scimitar. I've mixed it 10:1 with thinners, but added no hardener. It does take a long time to harden, but as I'm on a long-term rebuild, that doesn't bother me.

Hand rolled a mk1 fiesta, using a 60/40 mix of paint and thinners, chuck a few cans of laquer over it and it looked ok for it to sell on

I used 20% thinners (celly) when I painted the mini, but it was hot. When we wet saneded it a few months later, it flatted back fine with out any excessive cloging.

There's lots of good info here too.

In the states they seem to use Penetrol as a hardner, which seems to work.

I use thinners as well, somewhere in the 20-40% range. Makes it much easier to apply to the car.
But even with thinners you need to leave it much longer than you think before flatting it back, as rustoleum takes a lot longer to harden fully than normal spray paint.

Thanks for all the info! I have seen a good chunk of it all and the rest I have read.
I had some new tins of hardener which I have just tried mixing up with my leftover rustoleum and 10% thinners and I have painted it on an old panel so I am just waiting for it to dry to see what it is like.

You need at least a week before you try cutting it back. Do a thumbnail test on it, if it marks it isn't hard enough.

Tekaloid coach finish works brilliantly with brush, spray or roller.
