Just getting ready to apply silkspan to my f4. Been a while since I used this stuff. (25yrs)Its completly sheeted and I have applied 2 coats of thinned nitrate dope everywhere. Sanded with 600 very lightly and its now very smooth.
Can i overlap the silk span around leading edges and other joints? I reads somewhere that tearing the silkspan instead of cutting it is better?Will the ridge sand out?
Do I wrap the silk span around trailing edges and then re-cut hinges?
I have to glue the plastic nacelles on afterwards, will the canopy glue stick to the doped fabric? Also planning to use lustre coat primer on the abs nacelles and then butrate coloured dope to get a good colour match.
Also, I was just going to spray colored butrate dope right on the fabric after its all set and dry. Probably will take a couple coats of nitrate and sanding to get it ready for colour and I'm wondering if I will need primer as well?

I can't deal with the paint compatability issues, but the tearing of silkspan (using a hard-edged guide to avoid really ragged seams) is a good idea. It will be easier to blend in when you finish sand. Use a little spackling compound thinned with water to a "paintable" consistancy to coat the seams, then sand away everything but the smooth part !

I mix 50/50 dope and baby powder and apply that where edges of silkspan meet. Let dry and sand. Fills in all gaps very nicely and smells good too.
