Painting advice

[Glenn_Howard]

I've decided I'm going to have a go at painting some new panels. I have a decent quality compressor and spray gun and intend to use good old fashioned cellulose for a variety of reasons (already having the paint being one of them!).

 

Last year, I stripped the panels back to bare metal, made repairs and then protected them with a couple of coats of Bonda Primer. Is this okay as a base coat or should I remove it?

 

If it's okay, presumably I should flatten it off and give it a coat or two of grey primer? Can anyone recommend a suitable brand that works well under cellulose? Also, is grey primer usually mixed 1:1 with thinners?

 

It might turn out to be a complete disaster but at least I can say I tried! Any advice would be appreciated.

 

Thanks in advance!

Glenn

Make sure you etch the Bondaprimer with something like 150 grade otherwise your primer won't stick to it. Don't ask me how I know.

180 grit to key the Bondarust then use a good quality Cellulose primer,(ICI if you can get it) that can be mixed at 1/1 or thicker if required. then wet flat that with 600 then clean off with good quality spirit wipe then thoroughly dry off, wipe over with a tack rag and paint. Dont stint on materials so buy the best and check the composition of the thinners make sure its 100% pure and doesnt have any Methanol in it.

I also learnt that there is a thinner for the primer coats and a different thinner for the cellulose top coat.

the nice mans at the paint shop waited until I had a third done before telling me, but the early stuff looks OK.

I only put two coats of the final colour on. Now wish I'd sprayed a few more layers on. (Like Tony.)

 

There are plenty of books/websites around to give you a few clues/tips before you actually get stuck into it.

In addition to the above.

I bought the largest capacity compressor that would run on single phase 240 v.

When the painting phase came, I tried to find a spray gun that could handle the moderate capacity of the compressor.

After a bit of loooking up and reading, ended up with an Asturo AOM eco/sx.

Still had to have periodic pauses on the larger panels while the compressor caught up, but suspect I was better off than just using the first gun I came across.

Thanks guys

 

I'm relieved to hear that the Bonda coat doesn't need to come off. I'll prep it as you suggest and will start piling on some good quality cellulose primer.

 

I quite enjoy flatting each coat back, but ask me again in a fortnight ????

 

Cheers!

A few years ago someone on the forum asked how to go about spraying a car with cellulose. At that time I was just about going to spray my wife's Spitfire which I had rebuilt etc.

Stuart gave an excellent step by step layer by layer (I think it was 9 layers altogether) guide which I followed and achieved very good results. I didn't need to 'T' cut afterwards.

Perhaps yuo could ask Stuart to do it again.

Thanks, I'll try searching for it.

How much celulose do you need to paint a tr3 properly?

[stuart]

How much celulose do you need to paint a tr3 properly?

If your doing the whole shell inside and out and all the outer panels inside and out then 12ltrs.That will give you 4 coats over everything and leave you with just under a litre to use for future.
