Which body filler
smart51 - 17/1/11 at 07:50 PM

If you go to a big motor factors, you're faced with an array of different body fillers which, on closer inspection, are all made by Davids / Isopon. Are they in fact all the same or are some better than others? Should I just buy the cheapest one in the shop?

If I had a question about fibreglass I'd ask someone who did a lot and was really good at it....

Guess who I'd ask?

Your modesty does you credit Dave. Which would you recommend?

a dodgy back street garage?
yeah, i really want some of the really runny stuff you see them use on telly, but the stuff i always end up with in is more like lumpy peanut butter, i like the stuff that looks like it goes on like marmite

Go to a car refinishing specialist, they will be far more helpful. There is a huge variety indeed, some are extra smooth/resist pinpricks, some for going over galvanised and all sorts.

What are you doing with it?

I'm filling GRP taken from a male mould i.e. the rough side. I've sanded it with a long board to get rid of the big lumps and loose bits, now I want to get a smooth surface.

dolphin glaze may be helpful (or not!)

I find Upol Easysand to be the easiest ..... coz it's easy to sand

Seriously though, over the past year I have tried quite a few and that one was by far the best IMO.

I would go with this one too and if you want it a bit more runny add a wee bit of resin

Is this so you can paint it or make another mould? You could always use top coat if it's not too bumpy then flat this and polish it up

I've always used P38 and it does the job for me....

I'll paint them rather than taking moulds and making finished pieces from them. I'm rapidly approaching the end of year 3 of a 1 year build. I want to get it done.

When I used to repair fibreglass aeroplanes, the best stuff we found was Light Fantastic, rich creamy and smooth, ( almost good enough to put on your strawberries!) or Upol No.1....the cheaper stuff we called "bondo" was only ever used to stick wood together when we made jigs. Both the above are not cheap, ( you tend to get what you pay for) so go check out prices on eBay....best of luck. I use it all the time with my projects
