Whats the best way to sand filler on a curve  Previously ive just used sandpaper in my hand but never had good result . Rear wing just under the light cluster on the corner is the place to be sanded ..

[cem_devecioglu]

normally you may use small rubber foam sanding block but specifically the point you will sand requires by hand (imo) and fingers on sandpaper must be 90 degrees to movement direction otherwise you may leave finger traces


ps: assuming light cluster is not there otherwise mask it with several layers of tape..

I've been following a build thread and the poster has bought the full set ( very expensive ! ) and speaks highly of them. This was the cheapest so I though I would give it a go.
For concave curves I've just had this delivered but not used it yet .

Thanks Cem , used some foam type sanding block , after 600 grit found pin holes so had to fill again .. even spray filler would not hide the holes

Is that made of stuff similar to memory foam

pin holes means trouble what was the underlying base ? you must definitely correct the problem


and it could be that underlying base was sprayed quickly with several layers and inner layers may bubble up with the solvent (reducer)

for irregular curved places I cut some special shapes from foam blocks   also wood can be used to shape up easily

Just the filler didnt seem to lay flat after hardening , after a layer of primer i seen 2 or 3 pin holes that i missed when sanding

generally painters use thick layers to finish the job quickly..  but that causes more headache (pin holes and wet inside) ... tiny layers at a time ..sanding and adding another cures more quickly..

I hate sanding  I end up applying too much and sanding forever ! Can you apply top coat after 10 minutes of primer drying

you can but a bit risky.. imo better check the flash up times from the product catalog/can whatever..  however,  if you let the primer dry for few days, you may have the chance to see the underlying scratches so you can correct them by light sanding .. hurry in a paint job mostly ends with catastrophe.. and please remember to paint sharp corners first and let some time between layers

Today i feel unwell , bloody feet and back    Primer was applied yesterday so will leave it a few days , used 300/400/600 grit .. think before ive never really bothered with sanding in stages but looks like it will come out good this time . Thing is i lose my temper when it wont come out right  Painting is soooo slow and annoying , it mite be finished by xmas

Emd, may I recommend a simpler way..  just use an older 600 grid or even 800 alone.. otherwise you have to spray thicker , and become more tired..


pro painters here make this way when they have limited time (and it mostly works)


primer 7-8 layers ,- if surface is good enough-  sanding with 800
base 3-4 layer, for control , sanding with 1200
base another 3-4 and clearcoat

Thats ok then as i used a whole can on one small corner area , about 12 layers  Will try just 600 then

One particular piece keeps bubbling up under the filler , filler is only 1 mm deep  Ive cleaned and dressed the area 4 times now and the filler still lifts 

Does body filler go off  Ive had a tin about a year now , slight oily residue in the tin base but stirred that in
