Hi guys, 
Ive finally got the hang of making moulds and infusing. ive managed to infuse several times, however i get pin holes in the same area everytime, which makes me believe its the mould?

its an automotive part, so it needs to have a nice appearance but it also needs to be protected from the elements. 
i have experimented with XCR :
1. apply 2 coats of XCR
2. sand down with 180 grit until smooth
3. apply 2 coats of XCR 
4. sand down with 240 grit until smooth
5. apply final layer of XCR 
6. sand with 400 - 800 grit
7. polish

however everytime i apply a layer of XCR, by the time it becomes tacky it has loads of "craters" (see pic) 
it feels like a never ending process to get it smooth again and then apply another layer which again has craters when it drys!

the reason why i use XCR is to get hide of the pin holes and small dry spots in the corners on the finished product
but its an extremely long process! especially if i decide to sell this part.

is there a quicker method of using resin clear coat which will get rid of a small amount of pin holes and dry areas?

for e.g; can i apply 2 layers of XCR, sand down with 180 grit, and then spray some automotive clear coat ontop?
