I've tried my spray gun for the first time today. After a bit of playing round with the controls I got it to spray on some cellulost primer on quite nicely. That's after I worked out you have to hold the trigger all the way in if you want paint as well as air.

Anyway, what the paint has done is show just how bad my panels are. They are just full of little holes and craters, scrapes, scratches, gouges and "swage" lines that just aren't as straight as they seemed in the filler. I could get some more filler out and go over each imperfection, then re-sand it. Is there a better way? Is there a spray filler that can then be sanded back easily?

Use high build primer or primer filler.

You can get this from Halfords in a tin if youre desperate, and just use it on the areas that need it, ready for sanding down.

Other than that, skim the whole panel with filler, and sand back for a completely flat surface. To hide a crater using spots of filler is harder than it looks, and takes more skill than i have!!

I would use high build primer on the spots, and sand those back. This way, you can control how many layers you want to use in a particular area, without it going off in your hand and turning into plasticine making it impossible to apply.

I think what you do is spray 1-2 coats of high build primer, then spray a thin coat of black over the top, and sand that back. Any imperfections will show up black, which will need filling again and sanding back.

Alternatively, carbon dust (coal, charcoal etc) brushed over the surface is brilliant at picking up defects in the panels....

there is some stuff that's a two pack spray filler, not two pack as in isocyanate stuff but as in filler & hardener, you'll need a gravity fed gun though and a decent compressor, i used this some years back to good effect on a car i had to strip all gel coat off, you'll have to get it from trade outlet though.

The duratec surfacing primer/filler I'm using is the right stuff - Expensive, but it sands easily to a beautifull finish

This is sanded only with 240 grit so far, and wiped over with a damp cloth to see the surface

Fred WB,

Is that your plug youre still working on? Looks like youve made some great progress.

and in brum for paint (you prob use them already) use Jawel paints

Second time lucky and Jowel were open. I picked up some cellulose spray putty and it has covered nicely. It showed up a couple of pin holes that I'd missed and a heavy hand with the gun has filled them. Lumpily, but I'm going to sand it back anyway.

They guy in the shop said it should be thinned 50:50 like paint but it is thinner from the tin than the primer I've had. Should it be thinned or is it ready to use?

It is this stuff only cheaper and without the postage.

I've just read the ebay description which says ready to use.
