Revell plasto filler

Stitch,I use the glazing putty thats used on the 1:1 cars, it works great for me!

Stitch,the stuff that I use is called bondo glazing and spot putty
it comes in a 4.5 ounce tube, it for filling in scratches,pinholes and dings
on 1:1 autos but works great on models too,sands easy in about 30 minutes
there is a lot of other stuff out there,but this works for me.

Stitch,
 I , too use automotive glazing putty...and the results are A1...  HTH

Me three! Ive been usiing Bondo brand spot putty for the last 15 years or more. It easy to work with, heck of a lot cheaper than many products for models and it hasn't dried out or cracked in all these years! Its great stuff!
