Dont know the paint but to be on the safe side I would put varnish and NOT laquer on it,But as they are gloss paints why on earth would you want to put varnish or laquer over it

I always thought that was the usual process -  2 top coats of paint followed by a varnish/lacquer finish as a protective coat.
Maybe I should'nt bother then? Makes life easier!

As long as any paint is gloss then no need to varnish or laquer.Tbh even if it is a matt colour as long as it is  a plastic hull same applies

What are you actually painting, what colour are you using, as I can't see any mention of either?

Also, there should be technical data printed on the label. If not, find the Company's website as that will provide you with the recommended finishing instructions for their product, and all the Health and Safety blurb.

When using the terms 'Varnish' and 'Lacquer', nearly everyone is going to be thinking of a clear shiny finish, but, it's always worth specifing exactly which type of what product you mean, to avoid any confusion when asking for assistance on a worldwide website. Different countries may have slightly different meanings for the same word and vice versa. (e.g. UK and USA where Jam = Jelly, but Jelly = Jello)

If you're going to have to use a clear 'household' finish (and this is a generalisation), there are usually 2 choices; Varnish, which will often yellow over a period of time; and Polyurethane which won't, however...

...some of the finishes also claim to be UV stable (with varying degrees of success), and they will nearly all fall into two groups - spirit-based or water-based - Always worth knowing with regard to clean-up, and to comply with some local authority regs.

For reference, Rustoleum is one of International Paints brands, and they aren't all gloss.

I am painting a boat hull in two colours, both colours, off white & maroon, are
gloss spray.
Both paints are  by Rust-oleum and the lacquer that I have is also by
Rust-oleum, so there should be no problem with compatability.
 
Its just that I wondered if a gloss/or satin varnish would be a tougher
alternative to Lacquer and I can brush on varnish.
 
Its been difficult spraying anything lately with these colder temps.

Hi Nord',

I've had some experience with International Paints commercial products, which have been very good, but I haven't used Rustoleum. Do you have some reservations about the quality of the finish you've achieved or is this just a belt and braces exercise?

I had a quick look on the manufacturers website for you, and they seem to suggest that clear-coat is optional, but they did seem a little bit vague. oh, and they also make comment that clear-coating will dull some of their finishes (e.g. Fluoresent).

However, if you feel that you need to apply a brushed 'varnish' (and I will assume that we are referring to a domestic type product), I would bear in mind the comment made earlier it yellowing, and hope that some Mayhemers can advise of the best product for the job based on their own results if they have experimented as you are thinking.

If you are intending to make use of anything even slightly automotive-related, I would be asking Stavros for his help and advice - either in public or via PM.

Finally, if you don't get any answers you are happy with, find some scraps and then waste a couple of days painting some test pieces - You might make a useful discovery and it's a lot better than messing up all your good work.

Hello Andy,
 
I think that possibly the name'Rust- oleum' may be off putting.
This paint also goes by the name of Painters Touch and the finishes
I have obtained from their spray tins have been very good (in the right temps).
 
I am aware of the yellow tint that varnish leaves - on a dark colour this would
not be an issue but on an 'off white' it would not look that good.
Thats why I find varnish, ie  Rustins etc, not that good for light colours.
 
Your idea of experimenting with combinations was my intention but
the idea of posting on Mayhem promised faster results!
 
Thanks for your help.

Hi Nordlys,

I understand what you mean about the name 'Rustoleum' - It sounds like it's an alternative to Hammerite doesn't it!

With regard to varnish yellowing, it's normally associated with the oil-based variants, and isn't generally a problem attributed to Polyurethanes.
