Thanks guys for your advice. Looks like P38 then. Also does any one know of a person who buys vintage magazines, I have a 1967 copy of Radio Model and Electronics in fairly good condition.

I use a product called Dolphin Glaze, my local body shop put me onto it, its a bit on the expensive side

Dolphin Glaze
The Dolphin Glaze is a fine finishing glaze designed to eliminate pinholes and surface imperfections prior to painting. Its self-levelling formulation gives a smooth, ultra-fine finish which requires minimal sanding.

It is a two-component chemical liquid used for the final skimming of a polyester body filler putty repair or direct application onto minor imperfections on bodywork before overpainting. Also ideal for skimming over finished body filler, it offers high adhesion to galvanized, zinc-coated steel, cured paint and most plastics.

Aluminium, galvanised and zinc-coated substrates degrease and abrade with P120 paper. Do not apply over etch primer. Original paint surfaces (except for thermoplastic acrylics) – degrease and abrade with P180 grit paper. GRP – degrease and abrade with P80 grit paper.

Bondo, despite the smell. DAP makes a very nice plastic wood these days. Micro-Balloons is the choice of the airplane crowd. And I will admit that drywall mud has helped me over the years…but coated with Z-Poxy. 😊

I will give it a go, always good to try something new. thanks.

Have found that the Techniq Platinum Light Filler is great to work with. Found that P38 is too heavy, the Light filler is a delight to sand.

I agree P38 is a modellers best friend, it is strong, easy to use, inexpensive and will disguise many errors created whilst doing the clever bits.

P38 car body filler, easy and quick to apply and equally easy to sand, carve and shape

As I'm comming to the stage of covering and concealing all my cock ups, what's the best and easiest filler to use please.
