Hi,

This might be a really thick question to ask but is it possible to brush on paint that is intended to be sprayed on?

I am going to be getting some paint mixed for my mini but around the engine bay area I would prefer to hand paint rather than spray. Is the paint used for spraying suitable for being brushed on?

Cheers,

Luke.

Yes, cellulose paints and synthetic paints can be brushed on, as can 2k.

You will want a thicker consistancy (less thinners) for brushing it on however, and expect much higher curing times compared to that of spraying on due to the thicknes,.. lots of light coats.

You'd find rollering it on may give a better finish than brushing, and you can put lighter coats on too which leads to tougher paint and quicker curing times.

My question is, even if you're brushing it on,... you're going to be masking everything of correctly or stripping the bay yeah?.. so you might as well spray it with rattle cans anyway.

You have a very good point there about masking up and spraying. I have totaly stripped my engine bay down, everythhing is gone, subframe, electrics the lot. The reason I was considering hand painting is that I don't have a compressor that's up to the job yet and I would ideally like to get the engine bay painted and the front back together fairly soon.

Ask at the paint suppliers, oil based paints that are intended for use on commercial vehicles take longer to go off because it would take longer to apply a coat to the larger areas - makes a good choice for brushing. It's also not as whiffy as cellulose. One downside is that in certain light conditions the colour can appear several shades different to the same colour in celly or 2K so use only one type of paint.

I really think going the rattle can route would be a much better option, your local paint suppliers will be able to mix up 2-3 good cans for you of your desired colour (don't go to halfords for paint, you get more propellant than paint in those cans, utter rip off merchants)

I would use cellulose, it air dries (2k is best if baked and can take a while to cure if this isn't done),.. It's not particuarly wiffy, and since it's only in a rattle can you could do it with your garage door open and that'd be enough ventilation you also wont have to worry about mixing ratios. and no brush marks.

oh and stay well away from spray on hammerite, it's ball bag in a can.

I think I'll take your advice and go down the rattle can route. I just need to find a decent local paint supplier now and get some mixed up.

As for hammerite in a can, I've just discovered that it's useless. I bought some to spray my flip-front brace bars. I think I got more over my hands than I did on the brace bars!

have you looked at my camper van in the projects section

you can get good results with a roller and rustoleum

That might be the case but I always make sure that I carry out a search before posting! I was not able to find anything that I felt answered my question so I created a new post.

Now I will admit that my lack of finding the answer in previous posts could be due to the fact that I am searching for the wrong keywords but unless I find what I am looking for, I am going to create a new post.

Please feel free to point me in the direction of a post where this has been asked before and answered.

Thanks, Luke.
