Painting over rough fibreglass

[Paul B]

All I wanted to do was quickly splosh some paint on the rough underside of my 'glass body shell, to tidy it a bit. I tried a tin of Dulux Weathershield Satin Black, same as I painted my Morris with, but it looks like I am painting on grease proof paper.

:(

I wiped it all off, and I'm cross now. :mad:


It isn't a show car, nobody will be looking under there, I just wanted to tidy it up a bit and give it a little protection from the elements. Is there a special primer I need to use? Wipe with acetone? Roughen with an ice pick?

Sanding it is no good as it is rough 'glass.

Epoxy primer will stick Paul.

I didn't really want to get into all that complicated stuff until I do the finish paint on the topsides.

Do I have to spray it, or can I mix some up and roller it on?

[langysrodshop]

Its not really complicated Pal, You mix it 2 to 1 and whack it on, I brush it on the inside of GRP bodies to finish them off.

[weemark]

paul what about whacking on some body schutz? you can paint that on, never tried to roller it on though???

[Paul B]

Right, I'm off to the local purveyor of paint for some epoxy. :D

[kapri]

I spray schutz to try to soften the blows of stones etc and then brush synthetic over the top, not for show cars but good enough for something to use . Synthetic tends to take a coupl eof days to dry on top of schutz.

[langysrodshop]

Paul make sure you get EPOXY not UPOXY

You may have trouble getting it as its an industrial coating that not every paintshop sells.

[Paul B]

Hmm, local paint expert has no epoxy, so I might try the 'net for some.

Will Body Schutz stick well to 'glass?

[Paul B]

Anybody know a reputable on-line source of epoxy paint? I found a local place called Black Country Paints, about 10 miles from me, but haven't contacted then yet re. prices etc.

Try Jawel paints, I got most of my stuff from them. They do mail order & are based in Wolverhampton.

Aren't Joseph Mason's still in Derby???

I just called Jawels, they do a two pack acrylic, to be used over used with etch primer for fibreglass, but not an epoxy as such.

And when I looked up the http://www.masoncoatings.com/ website it gives a sexual content warning?!:eek:

Strange, must be all them fumes they sniff. :D

[Blackjack]

Paul - blackboard paint sticks well on the inside of fibreglass panels - it's cheap and easily found at B&Q.

I`ve used overpaintable sone chip on the underside of mine.Gives a lovely textured finish that can be left as is or painted over.Wouldnt use the `Shutz`,as it never really goes hard(unless you were happy with the finish and didnt need/want to paint over),and i dont think paint likes being applied to it.I would go over the`glass with a bit of 80 grit first.
I am planning on coating the inside of mine with the same stuff in the near future as it is coarse enough to hide the GRP matt as well as looking good.
Just my personal experience/preference.

you can`t paint over body shutz Mark as it doesn`t go hard, you can paint over stone chip though,

Is it very waterproof though?

Is 'Stone Chip' a specific product name? Or will any of the underseal type goops do?

It wouldn't be a bad idea to use something that really.

[BigBossMan]

have you tried Black Magic?


running away now! :)

[Russ]

just say stonechip Paul an they`ll know the differecnce it`s a generic name and most of the paint co`s do they`re own version, it can be coated over in 20 minutes

When I did the Engine swap on my car, I wrote a message on the gearbox. :D
Nothing interesting, just the registration number and the date I started the conversion.

Gravi-tex by Upol.

[ger]

But don't put Gravitex over smooth Hammerite......wrinkles up and falls off....Ask me how I know :)

Now my shop is airtight and can be raised above freezing point I might give it another go mate. :D

I'm off to a few paint stores today, so I'll see what they turn up, epoxy or stone chip, whichever turns up first. I've been eager to paint this floor for a week now. ;)

[wheelie]

Any marine shops near you, they should sell epoxy primers for fibreglass boats. Mind you, as soon as it's involved with "marine" the price shhots up.

None of them are difficult to get hold of, the first good paint store you go to should be able to sort you out with your preferred choice.

[langysrodshop]

Epoxy is difficult to get hold of as its not used in the day to day side of the painting business as its an added expense they won't run too.

Ok, my paint store supplied it easily enough when I asked for some last week to do my ally radiator.

[langysrodshop]

That maybe so Ian but you got lucky as not all keep it.

sorry russ meant gravitex, the stuff ross mentioned...

[Paul B]

DOH! I did a search for 'epoxy' as well and never noticed that thread. :confused:

Never mind, I just shot two rattle cans of Stone Chip over it and it looks okay, I guess. Probably the last time anybody will ever see it again now. Well, the body still has to come off to do the chassis properly eventually.

Rattle cans dont give any where near as nice a finish as the cans that need a`Schutz`gun and compressor to dispense...

I thought it was going on kinda thin......:(

[WagonMan]

I didn't even realise you could get stone chip in an aerosol, I've only ever had it in the Shutz type tin.

[cossie pop]

whats the differance now youve mentioned it :)

As far as I know Upoxy is just a brand name.

[langysrodshop]

Yes Upoxy is a trade name, When you go in paint shops that don't stock Epoxy they will give you Upoxy primer as they don't know any better. Ask Kapri as its happened to him.

this happened to my mate aswell, so be warned :eek::eek:

[crusty]

If your having a glass body made, ask them to 'flow coat' the inside of the body as this puts a smooth coat over the sharp glass matting you get on the insides of bodies, and its easier to paint.

Yup, and it's sh1te .If you bother to read the instructins you can't use polyster based products over the top ( no fillers stoppers etc ) and has none of the advantages of the using Epoxy that Steve quotes.

[redoxide]

folk near me do a spray on bed liner, ( for pick up beds) tougher than a tough thing on a tough day..you need the proper gear to do it though but its 100% chip resistent, watertight and will loose any glassfibre matt effect and sound deaden the shell all in one go.. Bound to be other folks do it across the country.. spray on bed liner.. :)

[evilzee28]

Any Lechler stockist will be able to get you Lechler EpoBuild. Water proof high build epoxy tintable to any colour. It is an industrial paint so works out about £50 gallon plus thinner and hardener. Good stuff, harder than a goats toe.


For the purposes of painting the unseen fibreglass panels, an epoxy primer is an excellent product. However, Lechler Epoxy is NOT guaranteed to be waterproof if left uncoated for any length of time. Their advice is to cover with top coat asap. If the primer is left on the panels for any length of time they recommend flatting the primer & then baking the panels in a low bake oven @ 80 deg to pull any residual moisture to the surface, then reflat again & top coat. I've recently talked with their technical department about this.;).
Over the years I've approached most of the paint manufacturers technical departments regarding priming a car with epoxy to seal it until it's ready to paint & they all said that their epoxies were not totally water/moisture impervious if condensation or rainwater was to get onto the paint surface. Lechler can't guarantee that moisture ingress won't occur either, but recommend the above steps be taken to try to alleviate any potential problems. hth.:)

[plumpcars]

Given the winter we've had it's a fair bet that there are a number of projects with moisture trapped somewhere beneath their fresh paint if not done in a booth.

I managed to get my garage up to a heady and tropical 12C today........ ;)

Next time I pull the body off for finish work and spraying the topsides I might set up and use a proper gun for stone chipping the bottom.
